For the instructions below, we’ll be using the Navisys GR-903 RTK Base(selling $599 at GPSWebShop), which is fully compatible with Ardupilot. It can be easily set up to inject RTK correction data into Ardupilot’s Mission Planner, which then transmits the data to an RTK rover connected to the flight control platform. Follow these steps to set it up.
1. Connect Your RTK Rover to the Flight Control Platform and Mission Planner
• If you haven’t already, connect your RTK rover to the flight control platform.
• In Mission Planner, select the correct COM port at the top right and click CONNECT. This will connect the Mission Planner software to the flight control platform.
• Once connected, you’ll see the flight data from the RTK rover streaming into Mission Planner.
2. Connect the Navisys GR-903 RTK Base to Mission Planner
• In Mission Planner, click on the Setup menu, then select Optional Hardware → RTK/GPS Inject.
• Choose the correct COM port for the GR-903, set the baud rate to 115200, and click Connect.
That’s it! Your RTK Base (GR-903) is now functioning as an RTK Base in Ardupilot’s Mission Planner.
To check the link stats, click the “Stats” hyperlink which is below the COM port in the top right corner.
