# H-RTK with CubePilot Controller

The Standard H-RTK F9P GPS can be used with CubePilot controller by connecting to **GPS 2** port.\
\
If using Ardupilot with The Cube, set **`Serial3_Protocol` to -1** so that Ardupilot will read GPS2 port for GPS data if there is nothing connected on the GPS1 port.

> ℹ️ **Info**
>
> **Note:** GPS2 port on both Pixhawk & Cube does not support Safety Switch function. You can use an external safety switch or disable the safety switch on ground control station application.
