配置

RTK setup and use on PX4 via QGroundControl is largely plug and play (see RTK GPS for more information).

接线和连接

The Here+ GPS comes with an 8 pin connector that can be inserted directly into the Pixhawk 2 GPS UART port.

The Pixhawk 3 Pro and Pixracer have a 6 pin GPS port connector. For these controllers you can modify the GPS cable (as shown below) to remove pin 6 and 7.

Pin 6 and 7 are for the safety button - these can be attached as well if needed.
