Indoor Positioning System VIPS

Accurate position detection without GNSS* in cooperation with Racelogic: With the VIPS (Indoor Positioning System), driving tests and crash tests with new sensor systems and safety functions can be tested in indoor facilities under constant ambient conditions.

VIPS works by utilising a network of stand-alone, battery powered beacons which communicate using ultrawideband (UWB). The beacons are placed around the perimeter of the operation area (eg floor plan of building or construction site), in known positions which have been manually surveyed using a handheld laser, Total Station or, if time is of the essence, a self-survey can also be performed. The accuracy of the known beacon positions directly corelates to the accuracy of the output measurement, allowing for flexibility in required accuracy verses set up time. The beacons are completely stand-alone, and the option of battery power makes deployment very rapid. A UWB receiver on the target object communicates with the beacons and uses trilateration to determine its position.

Together with Racelogic, a hardware was developed to link up the VIPS Rover to the GeneSys ADMA system. This allows the standardized ADMA data output with a positon accuracy which is equalent to operation with GNSS in RTK2 mode.

Technical Data

Up to 200 beacons can be installed on one site. They can either be surveyed using a handheld laser or Total Station for positional accuracy better than 2cm, or a self-survey can be carried out for positional accuracy between 5 cm to 10 cm. The beacons are completely stand-alone and can be battery powered, making the deployment very rapid.
