# Drotek XL RTK GPS
Drotek XL RTK (opens new window) (drotek.com)
RTK setup and use on PX4 via QGroundControl is largely plug and play (see RTK GPS for more information).
The Drotek UCenter tool is not required for configuration - everything is handled by QGroundControl.
The module inputs/outputs are shown here (opens new window) (Drotek docs)
