Is your test track lined with trees, featuring bridges or tunnels? Are you testing on public roads with obstacles obstructing direct satellite visibility?
VBOX 3iS, our speed sensor with inertial and wheel speed integration, significantly improves the accuracy of the speed and position data by combining wheel speed information from the vehicle’s CAN bus with GNSS and inertial data. In areas where there is no view of the sky at all, inertial sensors and wheel speeds can fill in the gaps for periods of up to five minutes. Additionally, the internal, high-grade IMU offers precise measurements of pitch, roll and yaw.
