INDOOR POSITIONING SYSTEM

Indoor positioning system

As  it becomes more and more difficult for vehicle performance and safety to improve, the requirements for testing become more stringent and complex.

Vehicle and tire manufacturers are addressing this challenge with increasingly tighter control of the test environment, which often involves moving test management regimes to indoor environments. Traditionally, vehicle speed and position information, which is key to many test analyses, is derived using GPS, which is not available during indoor testing. Now, working closely with VBOX customers, we have developed a solution that allows equipment and software traditionally limited to outdoor use to be used anywhere satellite coverage is limited or not available at all.


The system consists of a network of fixed beacons (Beacons) that communicate with a small roof-mounted receiver connected to an existing VBOX device. A standard VBOX IMU module is installed in the receiver, which further enhances the accuracy of the speed signal and also provides the attitude information of the vehicle. Our VBOX devices can seamlessly switch between indoor and outdoor environments, allowing continued testing in any test environment, allowing VBOX users to take full advantage of their existing hardware and software applications.
