# Autopilot Integration

{% hint style="warning" %}
Theseus Micro VPS currently only supports ArduPilot.
{% endhint %}

The Theseus Micro VPS communicates with ArduPilot over MAVLink. Several operations are performed:

* **Synchronize time**: the Micro VPS contains a real-time clock and synchronizes the time on your flight controller.
* **Pull sensor readings**: compass and barometer data are read over MAVLink and used by Micro VPS.
* **Send GPS data**: Micro VPS sends GPS inputs to ArduPilot over MAVLink.

This section goes over each parameter that needs to be configured in [ArduPilot](/micro-vps/autopilot-integration/ardupilot.md) and how to do so from [Mission Planner](/micro-vps/autopilot-integration/mission-planner.md) or [QGroundControl](/micro-vps/autopilot-integration/qgroundcontrol.md).
