Page 7: Using The Geosnap Pro
Using the GeoSnap Pro GEOSNAP FILES There are various text files stored and/or logged on the microSD card. These files, and their purposes, are described in this section. Configuration File (CONFIG.txt) The CONFIG file is where you can adjust all of the settings of the GeoSnap. Each time the GeoSnap is powered, it searches for the configuration file and reads the settings. - Page 8 Yaw as reported by the VN-200 gstime(ms) milliseconds GeoSnap time since power on AttUncrt(deg) degrees Attitude uncertainty of the VN-200 PosUncrt(m) meters Position uncertainty of the VN-200 INS_stat Status of the INS as reported by VN-200 © Field of View 2018 GeoSnap Pro User Manual...

Page 9: Synchronizing Image Names
The VN-200 requires dynamic motion to reach full heading accuracy. Because of this, if you are using the GeoSnap Pro on a multirotor, we highly recommend performing a few S-turns in manual flight mode at the start of the flight before sending it on its autonomous mission. -
