VBOX Precision Ranging System

Posted in Indoor/ Outdoor Vehicle Testing

What is VPRS?

The VBOX Precision Ranging System enables you to accurately measure the distance between two objects, in any environment. It is suitable for any application where you need to calculate a separation distance and does not rely on GPS, which means the system can also be used indoors.

How does VPRS work?

The VBOX Precision Ranging System consists of a receiver (rover) and a beacon, which communicate using Ultra Wideband. The rover is placed on one of the objects, the beacon is placed on the second object and the distance between each is then calculated by the rover to an accuracy of up to two centimetres.

There is no need to survey the position of either device, install any site control system or perform complex setup routines. Up to 5 systems can be used simultaneously and easily configured using the free VBOX Precision Ranging System setup software.

How accurate is VPRS?

We have built our own custom hardware, software and calibration routines which has resulted in an industry leading accuracy of ±2 cm. Having a variable update rate (up to 100 Hz) and low latency makes the system ideal for high dynamic applications and we also temperature calibrate the beacons, to ensure accuracy in all conditions.

How do I access the data?

VPRS on VBOX TouchThe data can be viewed live using a dedicated application on the VBOX Touch, which you can download free of charge.

If you wish to record the data so that you can analyse it later, you can connect the rover to any control system or data acquisition system, such as the VBOX 3i, via Serial or CAN. If you are using a VBOX 3i as part of your setup, you can also analyse the data in our user-friendly data analysis software, VBOX Test Suite, both live and after the event.
