"Cheap" RTK GPS system using Raspberry Pi's and uBlox ZED-F9P's
Use the Raspberry Pi installer to set up the pi user. I used the 64 bit Lite install of Raspbian. Ensure that SSH access is set up. I also modified the network configuration on the SD card to use a static IP for the ethernet adapter.
Most of this is already handled by ansible.
Edit the appropriate .service under the gps_control/startup_scripts and add the appropriate environment variables.
Copy the appropriate .service loop script into the /etc/systemd/system directory.
sudo systemctl enable <loop service>
suod systemctl start <loop service>
