ALTA X is a professional multi-rotor aircraft designed for demanding cinematic, professional, and industrial applications. Completely redesigned from the ground up, ALTA X is the next generation of the ALTA family. Built for the user, ALTA X emphasizes expandability and customization to make sure it can stand up to all challenges thrown its way, while still being the reliable workhorse drone that ALTA pilots know and love.

This Aircraft Flight Manual describes the complete operation of airframe and flight control systems, and the normal maintenance of those items. Do not operate ALTA X without reading and understanding this manual.

‌ This manual is not a substitute for adequate flight training. Training requirements can vary when operating in different countries or under different flight conditions. Always consult local regulations before flying ALTA X. In areas where there are no flight training requirements, it is the sole determination of the pilot-in-command as to whether he or she has the appropriate level of training or experience for a given flight. Always set and adhere to personal minimums and fly within your own capabilities.

Throughout the manual warnings, cautions and notes are used to highlight various important procedures. These are defined as follows:

ALTA X was designed from the ground up to be highly expandable and to support a large number of payloads. This section covers many of the integrations that have been tested.

For custom integrations, or to inquire about integrations in the works, please contact support!

DIU Blue sUAS - Alta X

Uses a Black Cube flight computer. This aircraft was developed and released in 2019 prior to the DIU Blue sUAS program.

Uses an NDAA compliant Blue Cube flight computer assembled in the U.S.A. This flight computer uses identical hardware as the Black Cube (original Alta X). The Alta X (Blue Cube) aircraft also utilizes specialized firmware that has been vetted and approved by DIU.

• Note: The Blue Cube is equipped with firmware that permanently disables WiFi and Bluetooth to comply with DIU Blue requirements and can only have Blue qualified firmware installed from the factory.

• Note: Alta X (Blue Cube) PN: 950-00112 does not include a hand controller. You can purchase a controller separately or provide your own.

• Note: Alta X (Blue Cube) and Alta X (DIU Blue Package) are NOT and will NOT be FAA Remote ID compliant from the factory.

Includes the Alta X (Blue Cube) described above, as well as a Pilot Pro controller with an RFD 900X telemetry radio. This encrypted radio sends and receives MAVlink telemetry and control inputs to/from the aircraft.

• As part of the Blue sUAS program, the Alta X is under strict revision control and updates in firmware or hardware will only be released after review from DIU.

• Limitations:

  • Freefly RTK does not currently work on the Alta X DIU Blue Package.

  • FRX Pro does not currently work on the Alta X DIU Blue Package.

  • The Alta X DIU Blue Package is not FAA Remote ID compliant.

• Important Security Guidelines for the User: To reduce the cyber vulnerability and increase the security of the system we recommend the following:

  • Logs: Aircraft flight logs are crucial for analysis in the events where logs are needed for technical support. However having logs enabled also pose vulnerability. If drone is intercepted mid-mission, and attacker gains physical access to drone, user can access unencrypted logs without authentication via physical access to drone, and can get current mission plan and logs. To address this vulnerability, you can set SDLOG_MODE parameter to -1 to fully disable logging.

  • Radio: The UXV tablet comes with password authentication to access the tablet. However the drone may still be armed using the joysticks without needing to access he tablet. To address this vulnerability, you can enable power to the radio using the installed RFD app upon every tablet login, then disable power after each use before shutting down the system.

IO Panel Upgrade

Broadcast Module Specs

• Output frequency: 2.4Ghz (2.402 - 2.481 GHz for Bluetooth 5)

• Transmit power: +18dBm (63mW) max

• Power consumption: Insignificant (~379mW peak consumption, which will decrease Alta's flight time by less than 0.15 seconds over a 25 minute flight for example)

Freefly's Skyview allows for payloads mounted on the top-side of the aircraft.

Pilot Notes and Controller Limitations

Pilot Notes

• Kill Switch Behavior

  • Any time the kill switch is activated (pulled down), all PWM signals to the motors will halt and the motors will immediately stop. If the unit is in flight it will not land gracefully.

    • This switch will work regardless of flight mode or other settings.

    • Once killed the unit must be power cycled to regain functionality. Even though QGround Control can send an 'Arm' command after the unit has been killed the unit will not spin its props.

• Safely Powering Alta X + Herelink

  • The Alta X cannot power the Herelink when only receiving USB Power.

  • In order to power the Herelink as well as the drone safely hold down the 'ACTION' button on the GPS until light pattern changes (~2s). On the Freefly RTK GPS the STATUS LED will flash white once and then the POWER LED will slowly flash Red.

Controller Limitations

• Pilot Pro Dials, Triggers, and Switches

  • As of right now only critical flight features are activated when using AltaX and Pilot Pro. These include the Mode Buttons, RTL, Kill Switch, and gimbals. We are working on updates to the FW which will allow users to have access to the Triggers and Switches found on Pilot Pro.

  • This includes A1, D1-4, L1/2, R1/2, S1/2, and both Rockers.

• Second External Telem Port (UART)
• HDMI Video

  • HDMI Video will not currently function through the QGround Control App - this is will be fixed in coming updates to the QGround Control App.

• Ethernet Drone Connectivity

  • While you will be able to connect a computer to the ETH port on the Pilot Pro's radio module and access AltaX, you will not be able to have a true ethernet connection with the drone.

FAQ's

• Can I fly a Alta X Herelink with a Herelink Controller?

  • We do not recommend flying Alta X Herelink with anything but Pilot Pro. Both the air and ground sides of the Alta X Herelink and Pilot Pro have been configured to work together and will not work with a normal Herelink. To use a Herelink Controller you would need to buy a off-the-shelf Herelink Air Unit and integrate the systems yourself.

Intro

Get Familiar

Before operating the Alta X with the Pilot Pro controller, ensure you have a solid understanding of the basics of the Alta X and are familiar with the differences between the various variants. It’s important to know what features your specific unit has and which ones it may lack. This knowledge will help you make the most of your equipment and avoid any confusion during operation.

First Time Setup

• The Pilot Pro controller is shipped with a factory-set password. Upon first use, you must change it to one of your own choosing, adhering to the following password requirements:

  • Minimum 15 characters

  • A mix of upper and lower case letters, numbers, and symbols.

• The Pilot Pro will come pre-bound to the Alta X, but will not show a green status by the power button until QGC is opened

Security

• Always keep the Alta X UAS and Controller physically secured. Unauthorized access to these items can allow attack vectors such as modifications of aircraft settings, or unauthorized exfiltration of confidential data and flight logs.

• Freefly records default passwords as well as radio pair encryption keys as part of the production process. If the user requires increased security it is suggested the user updates these items.

• Enabling LTE, WiFi, or Bluetooth will increase the vulnerability of the tablet.

Safety Warnings

• Even when Q-Ground-Control (QGC) is not open, the tablet is still sending RC controls. This is by design so that if the app crashes, you can maintain control of your aircraft. Always treat the tablet as being in control of the aircraft.

Getting Started

• Proper antenna placement is crucial for optimal performance. Follow these guidelines:

• On the drone, ensure the antennas face down as pictured.

• On the Pilot Pro controller, position the antennas vertically. Hold the controller with the long antennas pointing up or down, and avoid touching them to the controller's back. For the best performance and range, make sure not to point the tips of the antennas at the aircraft.

• Maintain line of sight with the aircraft for optimal range and connectivity. Plan missions accordingly.

• Be gentle when repositioning the antennas

Pilot Pro with RFD900 Controls and Buttons

• Take a moment to familiarize yourself with the locations of controls and mode buttons pictured below:

• Only the inputs in the image above are configured by default with the RFD900

Flight Part 1 - Flight Modes

• Startup flight modes - PENDING:

  • The drone starts up in PENDING flight mode, meaning it doesn't yet have a enough GPS position lock or home point.

  • The drone automatically switches from PENDING to POSITION mode when a position lock is available.

  • If the operator wishes to take off without a valid home point, they can click the mode button to altitude mode and take off anyway. Be aware that return failsafe will not function without a valid home point established before takeoff.

• (QGC) QGroundControl allows users to enter any flight mode via the flight mode dropdown, however, it is not recommended unless the user has prior experience with these modes. Use the controller buttons for mode switches and the on-screen slider for mission start when possible to avoid accidental mode changes.

Flight Part 2 - Operation

• Pilot Pro joysticks:

  • The Pilot Pro joysticks send SBUS commands directly to the aircraft and function even if QGroundControl is closed or the tablet stops working.

• Taking off in pos+alt mode,

  • To Takeoff, hold the left control stick fully down and right for 1.5 seconds to arm motors.

  • Once motors are at idle speed and all motors are running smoothly, push up on the left stick to takeoff and climb to the desired altitude.

• Landing in pos+alt mode,

  • Do not give positional commands during landing unless necessary, even minor joystick inputs when touching down can cause tip overs.

  • Once on the ground, keep throttle low and allow the aircraft to auto disarm in 5 seconds.

• RTL

  • Always check Return To Land settings for the operating area. Select an altitude high enough to clear any obstacles between any flight location and the home point.

  • A loss of link event will initiate an RTL (Return to Landing). When this occurs, the aircraft will climb to your preset altitude and fly directly to the home point. This should be accounted for when selecting a takeoff location to avoid tall obstacles.

  • To manually activate an RTL, center press the left directional pad momentarily.

Flight Part 3 - Emergency/Advanced

• Emergency shutoff:

  • In case of emergency, you can issue an emergency disarm from the Pilot Pro or QGC:

    • Pilot Pro: Flip open the Kill Switch cover and pull the Kill Switch down

    • QGC: click "armed" on QGC and swipe to shut down. This will work even when the aircraft is airborne

• Low battery

  • Low battery failsafe activation may occur early if the drone has low battery and high power demands.

  • The failsafe doesn't consider the drone's distance from takeoff when returning, so plan accordingly to prevent battery depletion.

  • To abort low battery, reselect position mode to override. Use caution!

  • Low battery thresholds may be adjusted for specific use cases. For instance you can decrease the threshold when flying close or with light payloads.

Pro Tips and Limitations

• Mission guidance:

  • The default mission and RTL speed have been increased to 10m/s in this firmware (5m/s was the default before). Users may need to override the speed in the mission if they previously relied on the 5m/s default.

• Charging time:

  • Charging time for the Pilot Pro is ~1Hr (@100W Charge Input)

  • Supplemental power can be provided to extend the run time by using an external USB power source, such as a battery bank.
• Freefly RTK does not currently work on the Alta X DIU Blue Package with the Pilot Pro controller.

MoVI Carbon makes a perfect companion to the ALTA X. When installing Carbon onto an ALTA, please note the following:

• To use MōVI Carbon with ALTA X, we recommend using the 40 duro isolators that ship with ALTA X.

• Install landing gear on MōVI Carbon and attach to ALTA X using the Toad in the Hole Quick Release.

• We recommend using qty 2 12s 16Ah flight packs with MōVI Carbon as this will allow 20+ minute flight times.

• The default Movi Carbon tuning should work well with ALTA X.

• FRX Pro can be added to MoVI Carbon to increase control range and robustness.

DJI's transmission technology works on various frequency bands, including non-DFS (Dynamic Frequency Selection) and DFS frequency bands. While this empowers filmmakers on movie sets, it also raises concerns about potential interference with aircraft (Alta X) operating within the same area.

The non-DFS frequency bands, comprising ranges such as 2.4000-2.4835 GHz, 5.150-5.250 GHz, and 5.725-5.850 GHz, are widely used by various wireless devices. DJI Transmission systems operating in these frequency ranges may unintentionally disrupt the operation of Wi-Fi networks, Bluetooth devices, and other aircraft connections. Such interference can lead to signal degradation, communication disruptions, or even complete loss of control for other devices sharing the same frequency spectrum.

Similarly, DJI's transmission technology in the DFS frequency bands, encompassing ranges like 5.250-5.350 GHz, 5.470-5.600 GHz, and 5.650-5.725 GHz, operates within frequencies that are subject to regulatory requirements to avoid interference with radar systems. Unintended interference from DJI Transmission can compromise the functionality of critical systems while working. This interference can pose significant risks to the safety and efficiency of any Alta X (and other Drone) operations in its vicinity.

Conclusion:

While DJI's transmission technology offers unparalleled connectivity and video transmission capabilities for cinematography, it is vital to emphasize the potential risk of interference it can cause to other aircraft (Unmanned & Manned) and systems operating within the same frequency spectrum. Responsible drone operation, adherence to regulatory guidelines, and airspace awareness are paramount to ensure the safety and efficiency of all aircraft.

Alta X can carry a wide range of LiDAR payloads. We often see customers integrate options from YellowScan, Inertial Labs, Phoenix Lidar, Riegl, and many others.

RIEGL

Gimbal Ready Alta X systems equipped with the Payload Vibration Damper (Alta X) have interchangeable isolator cartridges. The Payload Vibration Damper ships with 30A isolators, but they are available in different durometers.

These options give the user the ability to fine tune vibration damping performance for different payload weights or ambient temperatures. Durometer options include 30A, 40A, and 50A. The durometer of a cartridge is shown in recessed lettering on each of the O-rings. Use the chart below as a general guide choosing the correct isolator cartridges for your payload.

Radio Controller Calibration and Mapping

ALTA X can be used with a variety of radio controllers. Different radio controllers can map functions to different channels, so properly mapping controller channels to ALTA X functions is an important step before flying. Radio calibration and channel mapping are performed using the ALTA QGroundControl program or app.

If you are uncertain about your radio channel mapping, obtain assistance from an experienced pilot or from Freefly Customer Support.

Calibrating Radios Using ALTA QGroundControl App

Calibrating any compatible radio is done using the ALTA QGroundControl app. This only needs to be done when using a new radio with the ALTA X; ALTA X that were bought with a radio have already gone through the Calibration and Mapping procedures.

1. Power the ALTA X by plugging in a USB-C cable to the expansion port.

2. The expansion port is located under the closeout between booms 1 and 2 .

3. Once connected, the ALTA X electronics will be powered and you may turn on the radio.

4. Open the ALTA QGroundControl program, navigate to the Radio tab in the Vehicle Setup menu, and then initiate the radio calibration.

5. Set the transmitter mode radio button that matches your radio configuration (this ensures that QGroundControl displays the correct stick positions for you to follow during calibration).

6. Move the sticks to the positions indicated in the text (and on the radio image). Press Next when the sticks are in position. Repeat for all positions.

7. When prompted, move all other switches and dials through their full range (you will be able to observe them moving on the Channel Monitor).

8. Press Next to save the settings

Mapping Channels Using ALTA QGroundControl App

Radio channel mapping is accomplished with the ALTA Qgroundcontrol App. Prior to mapping channels, ensure your radio controller and receivers are properly installed and calibrated. Refer to the Radio Installation section of this manual and your radio controller’s documentation.

3. Open the ALTA QGroundControl program, navigate to the Flight Mode tab in the Vehicle Setup menu for access to the channel mapping.

4. Channel mapping can be customized by the user on this menu to fit their preferences. Below is a quick description of the items mapped to the transmitter and suggested channels for each mapped item.

Function Descriptions

The following functions can be mapped to radio controller channels. These are found in the Radio section of the Configurations menu in ALTA QGroundControl. Each function is also represented by a chart that responds to control input allowing for quick verification of mapping settings.

Controller

Use this to select the appropriate receiver. The following guide is compiled for convenience. For complete specifications and which mode will work with your receiver, refer to your radio controller or receiver manuals.

• DSM2/DSMX are typically used by Spektrum controllers

• SBUS is typically used by Futaba controllers

Pitch/Roll/Yaw/Throttle

The Pitch, Roll, Yaw and Throttle controls are the basic flight controls and are mapped to the two radio controller sticks.

Mode

The required Mode Switch selects between the three different flight modes: Manual, Altitude, and Position. A three-position switch is recommended to select the three different modes. However, a two-position switch may be used, but will only allow for selecting between Manual Mode and (depending on radio controller mixes) either Altitude Mode or Positon Mode . Other modes are available, but should be only used by experienced operators.

Return to Home Switch

The optional Return to Home Switch selects between the different Return-to-Land (RTH) functions. At minimum a two-position switch is required for the Home Switch functions to select between RTL Off, and initiate RTL functions.

Typical Channel Mappings

The following radio channel mapping configurations are recommendations only and can be set in ALTA QGroundControl. Depending on exact radio models, these may help as an initial configuration. However, it is up to the pilot setting up ALTA X for flight to determine if these settings are appropriate.

• Click LINK on the right side of the menu.

• Once the radio chimes and a pop-up opens, power on your aircraft or receiver.

• Under "Rx1" you should have a new serial number populated, this is the PID of the matching receiver.

• Alternatively, you can use an 850-00115 Futaba-to-USB cable to power the receiver if this is to be bound offline from the aircraft.

--------------------------------------------------------------------------------------

Arming and Disarming

Arming

To arm ALTA, put the throttle stick in the bottom right corner for 1.5 seconds. Upon arming, the propellers will start spinning and the boom LED indicator lights will turn bright green/red.

If the ALTA does not arm, please check QGroundControl for errors or warnings.

Disarming

To disarm ALTA, put the throttle stick on the bottom left corner for 1.5 seconds, you can also hold the stick straight down to initiate the land detector and disarm after once the UAV confirms it has landed. Upon disarming, the propellers will stop spinning and the boom LED indicators lights will dim. The aircraft will only disarm in flight in manual mode. Once landed, it can be disarmed in altitude and position modes.

Auto Disarm Modes

Under some conditions, ALTA will automatically disarm

--------------------------------------------------------------------------------------

Flight Modes

Manual Mode

In Manual Mode, ALTA X will only stabilize its attitude. At neutral control input (middle pitch and roll stick position), ALTA X will attempt to remain level. Throttle control is direct. In this mode, it will blow with the wind, and will require constant throttle adjustment to hold altitude.

Altitude Mode

Altitude Mode changes the throttle stick behavior to command climb and descent rates. The higher the throttle stick position, the faster ALTA X will climb. Conversely, the lower the throttle stick position, the faster ALTA X will descend.

When the throttle stick is centered, ALTA X will enter Altitude Hold. In Altitude Hold, ALTA X will maintain a target altitude and try to correct for vertical drift. If a disturbance moves ALTA X away from this target altitude, ALTA X will climb or descend to return to the target altitude.

Position Mode

Position Mode changes the pitch/roll stick behavior to command ground speeds. Pitch and roll stick deflection will command fore/aft and left/right ground speeds respectively. Controlling altitude in Position Mode is the same as in Altitude Mode.

With pitch and roll controls centered, ALTA X will enter Position Hold. In Position Hold, ALTA X will maintain its position over a given point on the ground and correct for disturbances.

Position Mode requires a strong GPS signal and communication with a minimum of 6 satellites. If a weak signal is present, ALTA X will not enter Position Mode

Waypoints Mode

Return-to-Launch

Return-to-Launch Mode will command ALTA X to fly back to the defined Home Point. When ALTA X first acquires a GPS position, it sets this as the Home Point of the flight. See the Radio Channel Mapping section in this manual for more information on setting up the Return-to-Launch Switch.

RTL can be initiated automatically with a LOS event if it is selected as the Signal Loss Action in ALTA QGroundControl. RTL can also be initiated manually while flying in any Mode and setting the Home Switch to RTL.

When initiated manually using the Home Switch, ALTA X will climb to the configured return altitude, fly back to the Home Point, and descend to 10m. ALTA X will hover above the home point and wait for a set amount of time and then land. The pilot can cancel the RTL procedure by returning the Home Switch to off.

During an LOS event, RTL followed by Autoland will be initiated automatically. ALTA X will first check its current altitude against configured RTL altitude. ALTA X will climb to Safe Height. Next, ALTA X will fly back to the home position at the default waypoint speed set in the ALTA X QGroundControl. Finally, upon reaching the home position, ALTA X will loiter for 45s and then begin to Autoland.

The Autoland function will land in place. The vertical speed at which the ALTA will descend during an Autoland varies as the ALTA approaches the ground. Higher above the elevation of the home point, ALTA X descends at a faster rate and gradually slows to the user-defined Autoland Descent Rate before landing. By default, the aircraft will descend at 0.7m/s until touchdown is detected.

--------------------------------------------------------------------------------------

Landing Modes

It is suggested that the operator lands in Manual mode, as it offers the most control for a precise touchdown. However it is possible to land in Altitude and Position modes as well. The aircraft behaves a little differently in each mode:

Manual Mode

In manual mode, the operator will maneuver the aircraft over the landing spot, and descend slowly using direct throttle control. As the aircraft nears the ground and enters ground effect, the pilot will often need to reduce throttle a little bit to keep the aircraft descending. Once touchdown is achieved, the operator should reduce throttle to zero promptly so that it settles on the ground instead of possibly bouncing or dragging the gear. Disarm as normal.

Altitude Mode

Landing in altitude mode is different than manual because the throttle stick now controls descent velocity rather than throttle directly. The aircraft will automatically adjust throttle through ground effect to maintain the same descent velocity. The operator will still need to manually control pitch and roll to maintain position over the desired landing site. Once the aircraft is on the ground, bring throttle stick to minimum, and then switch to manual mode and disarm. The aircraft will automatically disarm after 5 seconds if left running.

Position Mode

Landing in position mode uses the same altitude control as in Altitude mode, but additionally will control the position. This can be useful as it will fight the wind and drift automatically, but the aircraft may maintain a pitch and roll to do so, requiring care to avoid a prop strike on the ground or a tipover when using narrow landing gear. As the aircraft nears the ground, the maximum angle will be reduced to prevent large scale reactions to stick moments, but the operator should keep pitch and roll motions to a minimum when near the ground. Once the aircraft is on the ground, bring throttle stick to minimum, and then switch to manual mode and disarm. The aircraft will automatically disarm after 5 seconds if left running

Autoland Mode

It is possible to command the aircraft to autoland, as described above. It is not recommended in cases other than failsafe, or after careful testing. Autoland is not as precise as a human pilot, and certain payload combinations can result in tipovers or bouncing. Tall, narrow landing gear is particularly susceptible to tipover on autoland in high winds.

--------------------------------------------------------------------------------------

RC Disarm lockout

Introduced in FW 1.3.0, users can now configure a switch on their transmitter that, when enabled, will prevent manual disarm. Currently, users can disarm the aircraft in manual mode by holding the throttle all the way at zero, and the yaw stick all the way left for 1.5 seconds. In some cases, such as aggressive flying, this could happen inadvertently in flight, causing an inflight disarm and crash.

This feature only prevents disarming via RC command. Disarm via Alta QGroundControl still works the same, and an inflight disarm can still be forced through that interface. That mechanism requires a second confirmation step, so it is not able to be accidentally triggered.

Configuration

To configure, follow these steps while connected to the aircraft with Alta QGroundControl:

1. On the radio screen, toggle the switch that you want to act as the disarm lockout. Note on the channel list which channel number is changing when the switch is toggled.

2. Using the parameter screen, set RC_MAP_ARMLK_SW to the RC channel found in step 1.

3. Restart the aircraft

4. Test functionality, as described in the use section below. It is recommended to always test it before takeoff.

Use

Before every takeoff, it is advisable to test the operation of the switch while idling on the ground to ensure it is functioning. Follow these steps:

1. Set to manual mode

2. Set disarm lockout switch to OFF

3. Arm the aircraft, keeping throttle at minimum, idling on the ground with props spinning.

4. Set the disarm lockout switch to ON

5. Attempt to disarm the aircraft. It should not disarm, and a warning in Alta QGroundControl will show indicating that disarm was blocked by the switch.

6. Takeoff and fly mission

7. Land

8. Set disarm lockout switch to OFF

9. Disarm aircraft as normal

Note that to prevent confusion, the lockout switch must be set to OFF for the aircraft to arm also.

Troubleshooting

Switch reversed - If the behavior of the switch is reversed it can be corrected by reversing the switch output on the transmitter, or by setting parameter RC<channel>_REV to -1, where <channel> is the RC channel number for the switch in question. For example, to reverse channel 8, set RC8_REV=-1

Threshold - The switch usually maps between 0 and 1. The default threshold is set to 0.75, so that on a 3 position switch, lockout is not enabled until all the way in the 3rd position. If this needs to be adjusted, it is set by the parameter RC_ARMLK_TH

Mission Planning

Creation/Modification/Execution

To modify a waypoint, first click on it. The selected waypoint will turn green. Click and hold on clicking for a second time to drag the waypoint around the map. Latitude and longitude values will change automatically.

When the initial waypoint is added, a Planned Home indicator is automatically added. Initial waypoint will automatically be named as “Takeoff”. Planned Home is where the aircraft will land if a return to home signal is sent, unless there are rally points. Takeoff location is the first waypoint the vehicle will move towards as soon as mission mode is entered.

Users can observe mission specific values such as total mission time or total mission distance from the panel at the top of the screen. Once users are finished modifying a mission the mission needs to be uploaded to the vehicle. If a vehicle connection is established with the QGroundControl, a button named “Upload Mission” will be highlighted as soon as user makes a modification to the mission itself. Click on “Upload Mission” to load the mission file. Afterwards, go to “Flight View”. Uploaded mission can be executed from the Flight View by sliding the mission start slider or taking the vehicle into mission mode.

Detailed Mission Items

Advanced Users

Detailed waypoint list can be used to give commands at each waypoint. Command menu can be accessed by clicking on the three horizontal lines (top right of waypoint details panel). These commands will add an extra waypoint. The point of this waypoint is to indicate that there will be a command executed, it’s not really a physical waypoint. These commands include the following options: return to home, go to another waypoint, land and takeoff. Since the addition of the “command waypoint” might cause confusion, users are advised to get hands-on experience with simpler missions.

The Flight Speed variable inside the detailed waypoint list assigns a speed value that will be executed after vehicle passes the waypoint. For example, if default Flight Speed is set to 5 m/s and it is re-set to 20 m/s at third waypoint, vehicle will start to increase its speed from 5 m/s to 20 ms/ as soon as it passes waypoint three. So the target flight speed between waypoint 3 and waypoint 4 will be 20 m/s. Unless flight speed is reset back to 5 m/s at waypoint 4, 20 m/s value will be passed to rest of the waypoints.

Terrain Follow Mode

To ensure the safe use of Terrain Follow Mode on the Alta X, please adhere to the following safety guidelines:

1. Minimum Flight Height: Always maintain a minimum height of 20 meters above terrain to safely account for unexpected terrain changes.

2. Terrain Type: Best used over smooth terrain; the system may not accurately navigate large or sudden elevation changes.

3. Know Your Terrain: Familiarize yourself with the flight area. Do not solely rely on navigation data for flight planning and execution.

4. Data Use: The elevation data, provided by Airbus from the Copernicus Digital Elevation Model, is to be used at your own risk. Recognize that environmental changes and data inaccuracies can affect flight safety.

--------------------------------------------------------------------------------------

Tuning

ALTA X is pretuned by Freefly, and can be flown without changes. However, each user may have a different preference or use case for their aircraft. This section gives some guidance for how to tune some of the behaviors of the aircraft to suit individual needs. It is NOT recommended to tune low-level control parameters, as they could cause instability or control issues which could result in a crash.

--------------------------------------------------------------------------------------

Sensor Calibration

ALTA X features redundant, highly sensitive 3-axis magnetometers, gyroscopes, and accelerometers that measure specific force, angular rate, and earth’s magnetic field to infer heading and maintain stability. Occasionally, the sensors will require re-calibration.

Sensor Calibration Prep

Compass Calibration

Follow the instructions below to perform a compass calibration on ALTA X. Compass calibrations should be done when flying in a new location or when ALTA QGroundControl prompts a calibration.

Accelerometer Calibration

Follow the instructions below to perform an accelerometer calibration on ALTA X. Accelerometer calibrations should only be done when prompted by ALTA QGroundControl.

Level Horizon Calibration

Follow the instructions below to perform a level horizon calibration on ALTA X. Horizon calibrations should only be done if the horizon (as shown in the HUD) is not level after completing Accelerometer calibration and the aircraft is sitting on a level surface.

--------------------------------------------------------------------------------------

GPS Lights

The GPS module includes multi-color LED status lights that provide extra indication of aircraft status on the ground.

--------------------------------------------------------------------------------------

WIFI and FRX Connectivity

ALTA X provides two main connectivity methods for wireless telemetry: WIFI for short range, FRX Pro (optional) for long range. The wireless connectivity allows users to define parameters, monitor ALTA and configure missions.

WIFI

WiFi is most useful during preflight planning. WIFI is disabled by default, please see the next section for enabling WiFi.

After enabling the WIFI, connect your ground control device to the SSID (“ALTAX-[SN]"). Once connected, open QGroundControl, and it will automatically detect the connection and connect to the ALTA.

Enable and configure WIFI

ALTA X allows users to update the system’s WiFi password and SSID. All ALTA Xs initially come with WiFi disabled for safety reasons. To enable WiFi connectivity follow the steps below!

Configure WIFI settings

Reset Wifi

To reset the wifi, follow these steps:

The optional FRX Pro long range radio provides telemetry and aircraft control out to much longer range than the WiFi connection.

Disabling WIFI

FRX Pro

--------------------------------------------------------------------------------------

Datalogging

ALTA X provides comprehensive logging capabilities, which are enabled by default. In the default configuration, logging starts when the aircraft is armed, and ends when the aircraft is disarmed. These logs are stored on the onboard SD card, and can be downloaded to provide information about the flight.

Downloading Datalogs

Logs are stored on the onboard SDcard. To download them, follow the following steps.

View Datalogs

Log Cleanup

The onboard SD card holds between 8GB - 32GB of data, which is able to store logs for hundreds of flight hours. The ALTA X will start to delete old logs if it runs out of space, so it is useful to periodically clean out the logs if you don’t want them to be lost. Download all the logs as shown above, and then delete all (or some) of the folders in the “logs” subdirectory.

--------------------------------------------------------------------------------------

MAVLink

ALTA X supports MAVLink connection via two connectors, with one on the communications expansion panel on the outside of the aircraft (labeled UART) and one inside the aircraft.

External Expansion Panel UART

The external UART connection uses 57600 baud 8-N-1. This port is packet switch multiplexed with an OSD module, which means that there will be some periodic MAVlink parameter streams present by default for OSD use. Because it is packet switched, the user does not need to account for multiplexing their transmitted messages themselves, but instead just needs to plan for the fact that there will be some unrequested traffic received from the flight controller.

Internal Expansion UART

The internal port is prewired with a cable made available inside of the chassis. The connector is a JST GH 6 pin connector matching the standard dronecode/PX4 pinout. It is paired with a standard 4 pin GH CANbus connector for peripheral CANbus connections.

The internal port is shared with the WIFI module. To enable it for external communications use, you must ensure WIFI is disabled using the parameter “FF_WIFI_ENABLE”. WIFI is disabled by default, which means external communications are enabled. The internal port uses 921600 baud 8-N-1 by default but is modifiable using parameter “SER_TEL2_BAUD”.

This UART can be configured as a MAVLink “onboard” port, which enables a group of standard MAVLink streams for communication with an onboard companion computer.

External Computer Mounting

Power & Comms

Power is available from a few sources:

• 5V from expansion ports (see Expansion Ports section)

• 5V or 12V DC-DC converters

Communication to the aircraft is currently available through the Mavlink on the expansion port labelled "UART" (see expansion ports sections)

1. Flip your aircraft to access the underside of the chassis

2. Set it on a clean, flat horizontal surface to avoid damaging props if they are installed

3. Using the 4x included M3x10 'Combohead' screws and hex ball driver, loosely fasten each of the two rail adapters to the lower chassis, taking note of the position of the GPS unit to determine forward flight direction.

   2. The adapters can be mounted either parallel or perpendicular to the direction of flight, depending on your application. Most applications align with forward flight direction.

   3. The adapters can also be mounted angled inwards or outwards, depending on which suits your specific application best
4. Open the red locking levers and innsert the two 12mm x 500mm rails to the desired position within the clamps.

   1. Note that while the adapters are not tightened down, the tubes will be able to bring the adapter bores into alignment.
5. Proceed to tighten the red locking levers and then tighten the 4x chassis fasteners fully.

6. Flip aircraft right-side-up and proceed to attach your payload and landing gear solution.

Description & Specifications

The Freefly DC-DC converters draw power from the 50V battery bus and provide up to 120W of 5V or 12V DC. The converters utilize off the shelf converters mounted on a custom heatsink with and a custom capacitor board to provide better transient response.

Note 1: Above ambient temperatures of 50C, some current/power derating will be necessary.

Installation

The converter mounts onto any unused closeout. Installation steps:

Operation Notes

The power converter will power on automatically as soon as the battery is connected on the aircraft.

• The power converter will power on automatically as soon as the battery is connected on the aircraft.

• The converters have overcurrent & short circuit protection, and will restart automatically upon clearing of overcurrent/short circuit condition.

This section covers technical details of ALTA X.

Flip your aircraft to access the underside of the chassis

1. Set it on a clean, flat horizontal surface to avoid damaging props if they are installed

2. Using an M3 hex driver, remove 4x lower hinge bolts at both of the locations indicated (total of 8x)

   1. Note the position of the GPS module, the bolts to remove are located at either adjacent corner

   2. Note: these two locations will set the skid landing gear up in a standard 'forward flight' orientation. See Footnote #2 for more information on alternate configurations.
3. Apply a dot of the included Loctite 243 threadlocker to each of the 8x included M4x22 socket head cap screws
4. Install one of the aircraft-side leg mounts to each of the previously indicated corners of the lower chassis using 4x of the M4x22 SHCS
5. Using the included click torque driver and M3 hex bit, torque each of the M4x22 SHCS to 3.0Nm
6. Open the red adjustable locking levers on each of the aircraft-side mounts and locate the alignment rib inside the main bore.
7. Select either the Medium or Long length leg tubes per your payload and application

   1. E.g. Medium length legs are suitable for most lidar scanning payloads

8. Match the alignment groove on the leg to the aircraft mount and insert it until the safety latch clicks into the matching undercut on the leg

9. Once both legs are installed, tighten the adjustable locking levers to secure the legs

10. Open the adjustable locking levers on each of the skids and install them onto the end of the legs in the same fashion as the legs were installed to the aircraft, taking note of the alignment features and tighten the adjustable locking levers once the safety latches have engaged onto the skid.
11. Flip aircraft right-side-up and proceed to attach your payload.

• Footnote #1: The aircraft-side mounts should be left attached to the aircraft, not removed after every flight.

• Footnote #2: Depending on your application, you may choose to install the landing gear perpendicular to forward flight direction. Lidar scanning with wide angular sweep may benefit from this as it keeps the skid gear out of the line-of-sight of the scanner.
