As vehicle performance and safety keep improving, testing requirements become stricter and more complex. Vehicle and tire manufacturers are addressing this challenge with increasingly strict control of the test environment, which often means moving test management indoors. Traditionally, vehicle speed and position information — key to many test analyses — is derived from GPS, which is unavailable for indoor testing. Working closely with VBOX customers, we have developed a solution that allows equipment and software previously limited to outdoor use to operate anywhere satellite coverage is limited or completely unavailable.

The system consists of a network of fixed beacons communicating with a small receiver mounted on the roof of the vehicle, which is connected to an existing VBOX device. The receiver contains a standard VBOX IMU module that further enhances the accuracy of the speed signal and provides vehicle attitude information. VBOX devices switch seamlessly between indoor and outdoor environments, allowing testing to continue in any environment and enabling VBOX users to make full use of their existing hardware and software applications.
