Building a Docker image for a GPS module

GPS API

GPS data in NMEA format is forwarded to RPi IP address at port 5000, typically it is 10.15.20.2:5000. You can make sure the address is correct by typing http://10.15.20.1 into your browser (Username: admin, Password: Husarion1). Navigate to Services -> GPS -> NMEA -> NMEA forwarding -> Hostname and Port. Remember that you must be connected to the robot's WIFi network. If changes were needed, finish the connfiguration by pressing save & apply at the bottom of the screen.

Data frequency is 1Hz and can be interacted ether with GPSD daemon (gpsd -N udp://10.15.20.2:5000) or directly with ROS package redirecting signal to ROS topic.

It is recommended to use docker image. To start the container type:

git clone https://github.com/husarion/nmea-gps-docker.git
cd nmea-gps-docker

docker compose up

You should be able to see data on /panther/fix topic (rostopic echo /panther/fix).
