Log files for particular missions can be downloaded from the Gobi WebUI, but are also downloaded automatically when offloading a mission with GRYFN Processing Tool.
Full Gobi logs can be found in /data/gryfn.log.YYYY.MM.DD
Logs from the Headwall NanoHP can be found in /var/log/mvx/
Altitude estimate does not seem correct.
Elevations are reported in WGS84. Listed elevation should converge to nominal elevation after 2-5 minutes of static "warm-up" period for the SBG. If estimate does not seem correct after this time:
Ensure the GNSS antennae are installed correctly
Ensure GNSS antenna cables are connected to the right ports
Ensure the GNSS antennae are not covered
Ensure GNSS antennae have a clear, open view of the sky
If the above fail:
Try moving the aircraft to a new position, and adjusting the orientation
Try power cycling the aircraft to see if SBG is able to estimate elevation more accurately
Hyperspectral data did not capture.
Ensure the correct HSI capture polygon was uploaded to the sensor.
Ensure the HSI capture polygon and flight plan areas match.
Ensure the altitude estimate at takeoff was nominal.
Ensure the altitude trigger threshold was set at least 10m below the flight altitude.
Ensure the internal storage drive has enough free space to record data.
Can I hotswap batteries with GRYFN Gobi?
We do not recommend hotswapping batteries with any high-end GNSS solution. Static data can cause drift with the IMU and lead to a decrease in quality of the post-processed trajectory.
