Indoor positioning system

With the improvement of vehicle performance and safety, it has become increasingly difficult, therefore, the requirements for testing have become stricter and more complex.

Vehicle and tire manufacturers are using increasingly strict control over testing environments to address this challenge, which often involves transferring testing management systems to indoor environments. Traditionally, the speed and position information of vehicles are key to many testing analyses, which are calculated using GPS and are not available for indoor testing. Now, we are working closely with VBOX clients to develop a solution that allows devices and software traditionally limited to outdoor use to be used anywhere with limited or completely unavailable satellite coverage.

The system consists of a fixed beacon network that communicates with a small receiver installed on the roof, which is connected to an existing VBOX device. The receiver is equipped with a standard VBOX IMU module, which further enhances the accuracy of the speed signal and provides vehicle attitude information. Our VBOX devices can seamlessly switch between indoor and outdoor environments, allowing for continued testing in any testing environment, allowing VBOX users to fully utilize their existing hardware and software applications.
