# Vehicle Configuration

The Micro VPS needs to know the orientation of the flight controller relative to itself in order to accurately give a position estimate. The GCS App has a tool to define this transformation and save it to a file.

Check out our  [Mechanical Installation](/micro-vps/vehicle-integration/mechanical-installation.md) page for information on how to properly mount you Micro VPS and create the transformation.

## Changing the sysid

You might wish to change the sysid of your flight controller, but by default the Micro VPS searches for sysid 1. To change this default, you can use the vehicle configuration generator tool (≥ v1.7.7).

Create your vehicle config file and change the sysid/compid to the values used by your flight controller, then upload the config file, select it in the vehicle params dropdown, and finally restart the Micro VPS.
