NAVIGAT 3000

Product Description

Fibre Optic Gyro Compass

NAVIGAT 3000 Gyro Compass The NAVIGAT 3000 Compass and Attitude Reference System provides all motion data required for surface ship‘s steering. The fibre optic gyro compass that has the capability for precise sea alignment.

Key Benefits of NAVIGAT 3000:

• Less installation space needed due to its small size and low weight
• No moving parts for cost savings on maintenance
• High dynamic accuracy
• Very short settling time
• Provision of heading, roll, pitch, x/y/z rate and heave sensor
• Solid state, fully electronic strap down technology
• High Performance, Low Maintenance

The NAVIGAT 3000 Fibre Optic Gyro Compass  system is maintenance free (MF) meaning regular maintenance or calibration is not required. It provides precise heading, roll, pitch, x/y/z rate and heave  information. Unlike the classic spinning-mass gyrocompass, the fibre 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 gyrocompass. Because of their intrinsic reliability the NAVIGAT 3000 is used for high performance.

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 Features

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.

Easy Onboard Installation

An installation tray is provides for easy onboard installation, at any vertical mounting orientation,  where the respective mounting correction angles are entered in the NAVIGAT 3000 during installation. The NAVIGAT 3000 comprises Sensor Unit & Interface, Power Supply Unit & Control and Display Unit.

The NAVIGAT 3000 offers small size (volume = 3,6l ) and low weight (< 3,5 kg) for applications onboard mega yachts, cargo vessels and cruise liners.
