Information

• 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.

Specifications

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. 

The full NAVIGAT 3000 specifications are listed below:
 

  • Performance (under all conditions):

Heading                    ≤ 0.4° secant latitude RMS
Roll/Pitch angle      ≤ 0.1° for angles ≤ 45° RMS
Rate of Turn             ≤ 0.018° / minute
x/y rate                     ≤ 0.4° / minute
Heave                        0,1m

  • Will drive a max.  of 12 repeaters
  • Integrated monitoring of the supply powers, gyroscope current and follow up system
  • High speed follow up system 100°/sec
  • Automatic power changeover from AC mains to DC emergency supply and status alarm
  • Self-synchronizing repeater compasses
  • Electronic alignment error correction in setup program
  • 180° heading offset function for shuttle vessels
  • 6 independent serial outputs RS 400 & IEC 61162-1 and IEC 61162-2
  • 4 analogue outputs for rate-of-turn, roll and pitch signals
  • 2 independent 6 steps /° heading outputs (0.5A)
  • High Mean Time Between Failure (MTBF)
  • Power supply: 1x 115/230 VAC, 1x 24 VDC inputs
