TS-7180 GPS

The TS-7180 has an optional on-board Telit SL869 GPS receiver. An SMA female connector is provided for the connection of an antenna. This is accessible at /dev/ttyS7 where the GPS provides NMEA strings.

The GPS power is controllable through a GPIO. For example:

gpioset 5 19=1 # turn on GPS
gpioset 5 19=0 # turn off GPS

By default the GPS module is powered on.

A typical way of interfacing with the GPS is using gpsd. For example, under Debian:

apt install gpsd gpsd-clients -y

Then edit /etc/default/gpsd and change these two options:

# Devices gpsd should collect to at boot time.
# They need to be read/writeable, either by user gpsd or the group dialout.
DEVICES="/dev/ttymxc7"

# Other options you want to pass to gpsd
GPSD_OPTIONS="-b -n"

Then restart gpsd:

service gpsd restart

This allows clients from command line, or from most programming languages to interface with the GPS through gpsd:

• gpsd writing clients
