gps_minder

This program listens on the GPS tty interface (/dev/ttyGPS) for GPS messages and sends messages to the Inter Process Communications (IPC) hub with GPS updates.

Note that the /dev/ttyGPS should be setup system wide before this program is run. This is done by the Popufare system by creating a symbolic link to the appropriate underlying tty device that the GPS is connected to.

gps_minder listens for GPRMC and GPGGA NMEA messages to update it's GPS position.

Once received, the gps_minder will send a GPS_MESSAGE to the IPC so other services can get the GPS update.

GPS updates will only occur once at least 3 satellites have been found.

Building
