The TS-7120 has an on-board Telit SL869 GPS receiver. An SMA female connector is provided for the connection of an antenna.

Before it can be used, power to the GPS receiver must be enabled by setting GPIO #188 high, as shown below:

echo 188 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio188/direction
echo 1 > /sys/class/gpio/gpio188/value

The GPS receiver may then be accessed via the /dev/ttyS16 uart, at a default baud rate of 9600.
