The RTK Rover

The rover module is meant to be mounted on the vehicle that's moving. Whereas the base is supposed to be immobile (even though it can be mobile, which implies a loss of accuracy), the rover is the module receiving the corrections, providing the information to the autopilot with its position, heading, height, and so on. The rover does not require much configuration as long the baudrates are the same for both the GNSS modules for communication.
