Autonomous vehicles use many types of sensors to navigate, including satellite based systems such as GPS, to provide vehicle location with an accuracy of 1m.

In locations that block satellite signals, such as a parking garage, an alternative means of determining vehicle location is required.

Vital Alert extends the 2D positioning technology developed for locating pedestrians at intersections to a 3D system capable of providing location inside GPS denied environments such as an above or below ground parking garage.

In this application, the Very Low Frequency (VLF) positioning information will be integrated with vehicle’s sensors and navigation computer to allow the vehicle to navigate safely through a complex 3D environment.
