NAVIGAT 3000
• High accuracy, better than 0.1 degrees
• Free of scheduled maintenance, no moving parts
• Very fast alignment time down to 3.5 minutes
• Field data based MTBF of 130,000 hours
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 can be extended to a heading management system by using an operator unit and a distribution unit. The Northrop Grumman Sperry Marine NAVIGAT X MK 1 gyro compasses and magnetic compasses can also be added.
NAVIGAT 3000 Gyro Compass
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.
