# Deactivating Map Matching

You can deactivate the map matching functionality by toggling the button on the homepage of the dashboard.

Make sure you restart the VPS after deactivating map matching.
{% endhint %}

When map matching is deactivated, the VPS will only use Visual Odometry to provide position estimates. The position estimate will drift as you fly.

You do not need to load maps for the area of operations when flying without map matching.
