The GNSS module has a dedicated serial port at /dev/ttymxc2, operating at 9600 baud. You can use a terminal emulator to interact with this device:

root@pureos:~# picocom -b9600 /dev/ttymxc2
$GNRMC,,V,,,,,,,,,,N*4D
$GNVTG,,,,,,,,,N*2E

It is also supported by gpsd.

There is an additional GPS module on the SIMCOM modem. This modem is not meant to be used on the final phone. It has been shipped without an an antenna on the development board, making it inoperable.
