 # nmea-gps-docker
 Building a Docker image for a GPS module
+
+### GPS API 
+
+GPS data in [NMEA](https://en.wikipedia.org/wiki/NMEA_0183) 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](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](https://github.com/ros-drivers/nmea_navsat_driver/tree/decode-udp-line) redirecting signal to ROS topic. 
+
+It is recommended to use docker image. To start the container type:
+
+```bash
+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`).
