The VBOX 3iS (RLVB3iS) is a compact GPS/Inertial sensor which offers extraordinary precision and accuracy, by combining wheel speed data with a high-grade Inertial Measurement Unit and 100 Hz RTK GNSS receiver. In areas with limited or no satellite signal (such as tunnels or test tracks surrounded by trees), the VBOX 3iS can fill in the gaps for prolonged periods of time – allowing you to continue testing without having to worry about erroneous data.
Designed to be used with your existing control system or data logger, the VBOX 3iS offers accurate acceleration, speed, position and attitude data. It is designed for conducting tests such as performance, braking, ADAS and benchmarking.
For ADAS applications, connecting to another VBOX 3i RTK device enables the VBOX 3iS to act as a moving target and with RTK enabled, is capable of achieving 2 cm accuracy.
Thanks to a 100 Hz multi-constellation GNSS engine and the tracking of both the GPS and GLONASS networks of satellites, the VBOX 3iS ensures the accuracy of the data being captured even in restricted sky view conditions.
In GPS denied environments, such as tunnels and deep urban canyons, combining wheel speed information with the GNSS and inertial data makes a huge improvement to the accuracy of the estimated speed and position.
In this situation, the VBOX 3iS removes the need to fit expensive external wheel speed sensors that are difficult to fit and vulnerable to damage, by using the existing CAN bus information from the vehicle. Thanks to our comprehensive Vehicle CAN database, this is quick and easy to do as you can simply download the CAN file for each vehicle you are testing.
