High Performance, Low Maintenance

The NAVIGAT 3500 fiber optic gyro compass system is maintenance free (MF) meaning regular maintenance or calibration is not required. It provides very precise heading, roll, pitch, x/y rate and heave information. The fiber optic gyro compass has no moving parts and does not rely on inertial resistance to any movement. Hence, this is the most reliable alternative to the mechanical gyro compass. Because of its intrinsic reliability the NAVIGAT 3500 is the perfect fit for applications requiring high performance heading sensors.
