Installation on Astro

Install the GNSS antennas

Use the M3 screws provided to mount the GNSS Module mounts on the left and right side of Astro.

Install the GNSS antennas on to the mounts and slide the lock to secure them in place.

Attaching the Flux sensor

Insert the Flash Drive into the sensor and connect Flux to the Smart Dovetail connector. Secure the connection with the red lever.

Connect each antenna cable to its corresponding connector. Pull slightly from the cable to check that it is properly locked.

Setup your GNSS Base Station

To process the LiDAR data, a RINEX file is required to post-process the GNSS data from both antennas. This RINEX file contains the raw observation of the GNSS satellites during the scan from a fixed position on Earth. With this information, the computed GNSS position from the LiDAR can be improved dramatically. There are three ways to get this information:

Option 1: NTRIP RTK on Astro

In areas with cell coverage, Astro can stream RTK corrections using the LTE module via NTRIP. When Astro is setup with NTRIP, Flux will automatically save this data and include it in the .fluxscan file for processing.

Option 2: Third Party Base Station

If you have your own base station capable of logging L1/L2/L5/L6 GNSS in a RINEX file, set it up and leave it logging during the whole scan. You will need a .Obs file to process with at the end of the scan.

Option 3: Reference Network

If you do not have your own base station, check that there is a nearby permanent station from which you can download a RINEX file after your flight. There are available several GNSS networks from which these RINEX files can be downloaded, such as the HxGN SmartNet from Hexagon.

The further away the reference base station is, the less accurate your scan results will be
