The dual antenna (VB3ID) version uses two antennas placed at a fixed distance for measurement (pitch angle can be measured when installed along the vehicle direction, and roll angle can be measured when installed horizontally). By utilizing GPS and the Russian GLONASS satellite system, the RMS accuracy of slip angle measurement can reach up to 0.04 ° and the elevation angle can reach a measurement accuracy of 0.028 °. The testing accuracy of this system is so high that you can measure the small impact of crosswind effects on the slip angle of moving vehicles, even the best inertia measurement system is difficult to replicate this feature. In addition, the VBOX3i dual antenna system can capture the true heading angle, yaw rate, lateral velocity, and longitudinal velocity with low delay at a speed of 100 samples per second. The system provides a VBOX manager as a standard accessory for setting slip angle parameters and antenna spacing.

High precision RTK>VBOX3i can be used in conjunction with RTK differential base stations. Enable it to achieve an absolute positioning accuracy of ± 2cm, leading the VBOX3i to a new level of accuracy, which is very ideal for use in ADAS testing.
