The **Pixhawk 3 Pro** **autopilot** is an advanced system designed by **Drotek** and **PX4**. It features advanced processor and sensor technology from ST Microelectronics and a NuttX real-time operating system, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle. It was built in order to be **plug-&-play** with Drotek RTK modules, and is extremely reliable in RTK applications, as well as common vehicle controlling applications.

## Choosing the right module

Depending on your needs, you might choose a different module to use with your Pixhawk 3 PRO.

For a space constrained application, the [**DP0601 RTK GNSS F9P**](https://store-drotek.com/891-rtk-zed-f9p-gnss-1023.html#/105-case-without) would be the best choice, as it is modulable with the possibility to choose the adapted antenna. 

The [**Sirius RTK GNSS Rover F9P**](https://store-drotek.com/911-sirius-rtk-gnss-rover-f9p.html) module can also suit a space constrained setup with its **smart form-factor** and **built-in antenna** that will relieve the need of an external antenna to set up onto your vehicle.

The F9P RTK modules will offer a user-friendly installation as they are all three plug-&-play built specifically for the Pixhawk 3 PRO autopilot.

## Software configuration

‌

Using the Drotek **F9P RTK modules** with the Pixhawk 3 PRO autopilot requires very little configuration, as the autopilot takes care of most of the configuring process. Connecting your autopilot to the *Mission Planner* or *QGroundControl* software will allow you to tweak the parameters necessary to the well being of the RTK setup. You can follow the steps in the Rover and Base sections to find out more on the configuration process for the two modules.‌

Using QGroundControl or Mission Planner, you can check if the RTCM messages are present in the **MAVLink**. If they are present, then the corrections will automatically be forwarded to the rover module, which means your RTK setup is all right.
