Gyro Compass


The NAVIGAT 3000 high quality fibre optical gyrocompass system provides autonomous and fast heading alignment at sea.

The highly reliable Fibre Optic Gyro Compass (FOG) provides a compact and very cost effective AHRS (Attitude and Heading Reference System) that offers simplicity of use, reliability and very high accuracy. Standard NAVIGAT 3000 features include the provision of roll and pitch data x/y/z rate and heave in addition to heading information, with a settling time of maximum of 30 minutes. Its solid state nature is unaffected to speed / latitude error and provides 12 serial interfaces for heading repeaters plus 6 serial interfaces for heading receivers and analogue outputs. Besides the primary sensed angular rates and acceleration in all 3 axes also the velocities and dynamic heave are computed and transmitted.

The NAVIGAT 3000 Fibre 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 manoeuvres.
