Current Firmware Version

Astro v1.5.18
  • Summary: Remote ID Support, Astro FPV integration, ESRI Site Scan and other bugfixes

  • Release Date: March 2024

  • Versions in this package:

    • Astro Skynode: v1.5.18

    • AMC (Android): v1.26.15

  • Notes

    • New: Added Sentera 6X and 65R options to AMC

    • ESRI Site Scan is now compatible with Astro v1.5 and above

    • Mission and Surveying Fixes:

      • Fixed a bug in the execution of missions with altitude changes. There was an issue with aircraft not always following the intended vertical flight trajectory between waypoints.

      • Fixed a bug where geotagged altitudes could be wrong when using a USB camera

      • Improved the Sony A7RIV triggering consistency during surveys. The jitter between triggers is now significantly reduced

      • Improved RTK geotagging. Previously, the vehicle's location was used to geotag images onboard the vehicle. Although the PPK workflow corrects for any shift during post-processing, accurate RTK geotagging must occur onboard for optimal precision.

      • Improved the speed in generating the necessary onboard PPK files by over 3 times

      • Fixed an issue with PPK process writing the same capture event twice in the Rinex file

      • Fixed issue that would cause the PPK status in AMC to be incorrect. In some cases the processing popup would never show up while in other cases it would show up but never go away

      • Fixed the 200 feet constrain on corridor width limit

      • Known issue: Site Scan Reality Engine does not correctly process the gimbal attitude, resulting in poor output maps. Current workaround is to use the Legacy Engine

    • More

      • Optimized video streaming to the GCS by reducing the number of data spikes over the radio link

      • Added VEHICLE_MANUFACTURER and MODEL for XMP metadata for easy ingestion by Trimble Business Center

      • Updated max yaw rate to 75 deg/s for more precise control

      • Added a guard to battery emergency logic. If a battery reports a sudden jump to 0% state of charge, Astro will do additional checks to see if this might be a faulty report, then it will initiate an RTL instead of a direct Land action.

      • Fixed and issue where slow mode intermittently using wrong camera for scaling

      • Improved data usage by not uploading photos to the suite that are taken while the drone is disarmed

      • Optimized photo storage on external USB stick. Depending on the usb stick write speed there could be situations where the photo storage would slow down the rest of the payload operations.

      • Fixed an issue that would cause the payload to never be detected after a brief payload disconnection

      • Added ability to center map on vehicle, on payload Center Field of View or both

      • Added software compatibility check between AMC and AuterionOS

Astro v1.1.18
  • Summary: Several hotfixes that address safety critical issues

  • Release Date: February 2023

  • Versions in this package:

    • Astro Skynode: v1.1.18

    • Herelink OEM build number: FFARU010624


  • Several hotfixes that address SD Card driver and priority issues that caused an Astro to crash

    • Hotfixed SD Card driver to eliminate a possible hang when the SD card is disconnected during a wait for write to complete. This was the initial cause of the crash that triggered grounding

    • Removed PX4’s emergency logger priority boost mechanism which could hang the system if the logger or log_writer thread was already hung (possibly due to the above issue). This priority boost is what promoted the stuck logging thread to max priority, with the intent of capturing what was wrong, but instead caused the processor to hang in the high priority loop.

    • Increase semaphore holder slots so that there is no situation where it could run out during a resource contention. This can happen during shutdown where multiple modules write parameters at the same time.

    • Hotfixed px4io module to ensure DMA is properly closed and restarted in case of a transfer failure

    • Hotfixed px4io module to ensure that in case of corrupted SBUS data, the input processor can’t try and process more than the valid data

  • Hotfix for GPS dropouts affecting Astro functionality

    • Default GPS configuration now disables Beidou constellation processing on the F9P GPS. There is a suspected weakness in the GPS firmware where bad SBAS data may cause added CPU load on the GPS and it becomes overloaded, which may cause GPS lock to drop for a few seconds.

  • Known issue: During testing, a Freefly Engineering aircraft failed to fully complete the disarm process. The motors shutdown, but the system hung. This has happened 3 times to this specific aircraft, including on older firmware. It is still being investigated, but we don’t believe this was added in this firmware. It has only happened to one vehicle, and failed safely each time.

  • Testing for this release included

    • Hotfix specific test plan for the new changes

    • Full software validation testing

    • 50+ hours of functional flight time across over 10 pilots and Astros

Astro v1.1.14
  • Summary: Introducting ESRI Site Scan for ArcGIS integration

  • Release Date: September 2022

  • Versions in this package:

    • Astro Skynode: v1.1.14

    • Herelink OEM build number: FFARU010624


  • New Feature: Integration with ESRI Site Scan for ArcGIS!

    • Complete solution - Freefly Astro integrated with Site Scan for ArcGIS provides a complete end-to-end drone mapping solution. From drone hardware, automated flight planning and execution, online and offline, to imagery processing on the cloud or on desktop, to advanced analysis in ArcGIS…

  • New Feature: ExFat support. You can now use USB drives with any memory size, and format them using a Windows computer. Simply select ExFat format.

  • Improvement: auterionOS and AMC now uses a global counter for the pictures taken

  • Bugfix: Fixed the camera pre-flight check fails

Astro v1.1.11
  • Summary: Astro Map initial release

  • Release Date: May 2022

  • Versions in this package:

    • Astro Skynode: v1.1.11

    • Herelink OEM build number: FFARU01220425


  • Operational Behavior Changes

    • New Feature - Failsafe change: Before executing critical and emergency battery failsafes, Astro now switches to “hold” mode for 10 seconds and shows an alert on the AMC. This allows the pilot to have an opportunity to take any manual action, such as aborting the RTL incase vehicle is operating below obstacles. RTL can be be cancelled by selecting any other flight mode.

    • New Feature - Initial mode behavior change: Astro will now boot into PENDING mode, and will transition to Position mode when GPS accuracy requirements are met. This prevents accidentally taking off before the Position mode is available and being confused as to why position hold and RTL failsafe is unavailable. If the pilot wants to takeoff before this (without GPS), they can switch to Altitude or Manual mode.

    • New Feature: Astro will now go through a 3 stage landing for a smoother touchdown. This autoland is available within 50m horizontally and 30m vertically from the takeoff location. Outside of these bounds, Astro will autoland using the 2 stage touchdown, as it did in v1.0.21.

    • Improvement: Mission pause and resume actions will resume the mission from the last completed waypoint

    • Improvement: Mission and cruise speed defaults are set to 10 m/s

    • Improvement: Default mission altitude is set to 50m

  • System and Other Changes

    • New Feature: Astro will now GPS geotag the photos with high accuracy and move them any attached USB storage device. High accuracy is achieved with the integration of camera hotshoe signals, and 1PPS time synchronization

    • New Feature: Astro will automatically write GPS observation files to any attached USB storage device at end of flight for use in PPK processing of flight path or photos. If the aircraft is powered off before observation file writing is complete, it will be placed in a recovery folder on the USB drive at next boot.

    • New Feature: Herelink runs an additional app (Skyway) to route telemetry and video to hotspot devices. This allows connection of multiple devices to Herelink hotspot and stream data and video from Astro

    • Improvement: Astro prevents flashing non-Astro firmware releases to Skynode

    • Improvement: Astro requires a magnetometer calibration after firmware update and parameter reset

  • AMC Changes

    • New Feature: AMC will display estimated flight time remaining in minutes as a bar at the top of the screen

    • New Feature: Herelink radio signal strength indicator in status bar

    • New Feature: Support for Astro Map system

    • New Feature: Progress indicator after landing to let users know when GPS observations are done processing. You can set aircraft parameter GPS_DUMP=0 to silence this notification (which will also disable writing data necessary for PPK processing).

    • Improvement: AMC now runs in background. Minimizing AMC app won’t trigger datalink failsafe

    • Improvement: Auterion suite pilot login

    • Improvement: Terrain collision calculations are improved when planning a mission

    • Improvement: UI for maximizing video window is improved

    • Bugfix: Performance impact of capturing hundreds of photos during a survey is reduced

    • Bugfix: Corridor scan will now trigger photos on all flight legs

  • Developer/advanced user Changes

    • New Feature: 1PPS pulse is available on the IO board ZPD connector

    • New Feature: Support for Mavlink Gimbal protocol V2 -

    • New Feature: Camera trigger and feedback is enabled
