Integrated in the MSS400 series sensors, the SP technology (inertial guidance) allows for the execution of excavation work at speeds never seen before, and this, with no loss of precision. Combined with a gyroscope, SP technology improves GNSS performance in hostile environments which sometimes cause the loss of satellite signals, such as wooded areas, urban canyons, mountainous terrain, etc. As compared to past generation sensors, series MSS400 systems are up to 20% more durable and need 30% less calibration time.
