How to manage the Internal GNSS

The ReliaGATE 10-12 exposes the GNSS as follows:
/dev/ttyS5
l
You need to enable the GNSS before it will work.
To enable the GNSS, enter the following command:
gpio_utility gpio81 1
To prove that the positioning is working, dump the serial port output by entering the following
commands:
stty -F /dev/ttyS5 raw speed 9600
cat /dev/ttyS5
Example output:
$GNGSA,A,1,,,,,,,,,,,,,99.99,99.99,99.99*2E
$GPGSV,1,1,00*79
$GLGSV,1,1,00*65
