VIPS offers a highly accurate way of measuring speed, position and attitude (pitch/roll/yaw) in areas where GNSS is not available. With a 100 Hz update rate, the same ±2 cm level of accuracy that is equivalent to GNSS with RTK, and seamless transition from outdoors (GNSS) to indoors (VIPS), it is a cutting-edge addition to any autonomous guidance system or test programme.
