Shell Script which saves the GPS data to a CSV file in Micro SD card for NetComm Wireless NTC-140 and NTC-140W routers.
Download 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.
Script saves the GPS latitude and longitude coordinates in the file if the coordinates differ by certain distance (in this example 5 meters). Flow chart is attached below:
Sample gps.csv output is attached below:
