fiber optic gyro

The NAVIGAT 3500 fiber optic gyro compass model has a clear advantage over spinning mass gyro compass models as it has no moving parts, no maintenance during service life, high dynamic accuracy, no north speed error, a short settling time and output for roll and pitch. Safety is increased as a result of the high dynamic accuracy associated with the lack of north speed error. This is particularly valuable for high-speed craft at high latitudes during frequent maneuvers.

When precision matters, be in position.

Our unique networked fiber optic gyro compass system solution. Maintenance free strap-down technology without moving parts ensures long endurance, with MTBF of 150,000hrs, wherever you are heading.

Recommended for following vessel segments:

Merchant incl. LNG and Tanker, Passenger, Cruise, Mega Yachts, OSVs, Dredgers, Coast Guard, Research, HSC

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.
