• Northrop Grumman Sperry Marine has designed the CompassNet heading management system to deliver an unrivalled system solution for comprehensive multiple heading management control. The CompassNet heading management system uses Ethernet connection for all communication between the connected heading sensors and the heading distribution and heading management system. A complete new set of heading sensors, both spinning mass and fibre-optic, will be available for connection to CompassNet.

  • CompassNet provides you with a system that is both reliable and easy to use. CompassNet offers many benefits, including:

    • Low cost and ease of installation
    • Outstanding performance
    • Improved efficiency
    • Variety of configurations
    • Type-approved.
  • Northrop Grumman Sperry Marine is the first company to employ Ethernet technology in its heading management systems. This reduces the complexity of installation, simplifies operational performance and guarantees improved reliability and navigational safety. With less wiring, it’s quicker, easier and less expensive for you to install and commission. Because there are fewer connections, it’s also easier to connect a range of additional equipment to enhance your heading management requirements.


  • The NAVIGAT X MK 2 digital gyrocompass system provides a cost-effective solution that satisfies the international carriage requirements for a type-approved marine gyrocompass.

  • The NAVIGAT X MK 2 gyrocompass is a compact, one-unit design that runs on a 24-volt power supply with two independent DC inputs. It can drive up to four analogue repeaters and provides five additional serial data outputs and one six-steps / degree output.

    Based on the proven Sperry Marine NAVIGAT X MK 1 design, the new gyrocompass provides better than 40,000 hours mean time between failures (MTBF).  The system remains north-stabilized for up to three minutes in the event of a power interruption.

  • The NAVIGAT X MK 2 complies with the International Maritime Organization (IMO) regulations A.424(XI) and A.694(17) as well as the International Standards Organization (ISO) standard 8728, and is fully Wheelmark type-approved.

    The introduction of this new gyrocompass completes the Sperry Marine range of heading sensors, which now comprises the NAVIGAT 2100 fiber-optic gyrocompass, the NAVIGAT X MK 1 and NAVIGAT X MK 2 digital gyrocompasses.
