# Vehicles

The Vehicles page allows you to generate and upload maps prior to your operations with the system. This is also where you can set your home/takeoff position and switch between generated maps.

## Why do I need this?

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.
