Xsens Vision Navigator

Outstanding positioning information, even in GNSS-deprived areas.

Accurate localization, anywhere

When it comes to outdoor (and indoor) autonomous vehicles, it’s essential to know precisely where the vehicle is located at all times – even in challenging or GNSS-denied environments. For these applications, Movella have introduced the Xsens Vision Navigator.

Visual-inertial odometry

Using dual RTK GNSS, an internal IMU and a camera, and visual-inertial odometry technology, the Xsens Vision Navigator provides accurate real-time navigation data, whether you’re in a forest, an urban environment, a warehouse, a tunnel or even underground.

Position drift over distance

With the Vision Navigator, position drift is distance-dependent as opposed to time-dependent – as commonly found in more traditional GNSS/INS devices. Because of this, the Vision Navigator is able to cope with continuous GNSS disturbances or long-lasting GNSS outages.
