About and Execute Script
Download, extract and move the script file (cgps.template) to /etc/cdcs/conf/mgr_templates directory of the router and give it executable permissions by running chmod +x cgps.template command. The script should create a gps.csv file in your Micro SD card located at /var/mnt/SDDisk0P1/ directory of the router with GPS data.
After file is created new data is only saved, if the last saved GPS coordinates are different than new ones by certain distance (in this release - 5 metres).
Flow of Script
