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.
