NORTHROP GRUMMAN SPERRY MARINE

    NAVIGAT X MK 1

    NAVIGAT X Mk 1/SR-180 Mk 1 is a microprocessor controlled gyrocompass system
    with integrated automatic north speed error correction.
    The system is type approved by the German Federal Maritime and Hydrographic
    Agency (BSH) and complies with IMO resolutions A.424 (IX) and A.574 (14) as well
    as DNV-W1 and ISO standard 8728.
    For use in high speed craft, an optimized system is available, which complies with
    IMO resolution A.821 (19) - HSC.

    C. PLATH's unique method of supporting the gyrosphere by means of mere buoy-
    ancy ensures north stabilization during short power failures. For example, after a
    three minute loss of power, no more than two degrees of deviation may be expected.
    Once power has been restored, the gyrocompass will return quickly to the correct
    heading without requiring the usual settling period. The combined effects of the twin
    rotors an the liquid damping system virtually eliminate latitude error.
    Heading is measured as a 12 bit absolute value by means of a digital shaft encoder.
    The high-speed follow-up system (>100%/sec.) ensures extremely accurate meas-
    urements of heading and rate of turn under all operating conditions.
    The system features an integrated TMC-function (magnetic compass transmission)
    and input interfaces for a second gyrocompass, speed log, position receiver and two
    rud angle feedback units.

    The gyrocompass provides 12 independent serial data outputs to analogue or digital
    repeaters (including short-circuit-proof 24 VDC repeater power supply), RS 422 and
    NMEA sensor data outputs, a special NMEA Fast output interface (reduced dataset)
    and a NMEA Superfast output interface (adjustable baudrate, max 38400 baud). Fur-
    thermore, two 6 step/0 heading outputs, an analogue rate of turn output and an inter-
    face for the voyage data printer NAVIPRINT are provided.
    Integrated monitoring and alarm functions for the supply powers, gyroscope temperatur
    and current and the follow-up system ensure secure and trouble-free operation of the
    system.

    The single unit design with a polyurethane hard foam housing of low weight allows
    the gyrocompass system to be installed on any bridge, from large yachts to the most
    capacious merchant vessels. If required, the integrated control and display unit may
    be installed at a remote location from the gyrocompass or an additional remote oper-
    ating unit installed.

    As an option, a special "compass monitor" control unit is available, which provides
    additional independent monitoring functions and features a numerical keypad, which
    facilitates the operation of the system.
    An optional switch-over unit for twin gyrocompass systems provides for complete
    redundancy of all in- and output signals and thus ensures the independence of the
    individual compasses.

    NAVIGAT X MK 2 OPTIC

    The NAVIGAT XMK2 is a microprocessor controlled gyrocompass system with
    integrated automatic North speed error correction.
    The single unit design with a polyurethane hard foam housing allows the gyro-
    compass to be installed on any bridge. If required, an optional remote operat-
    ing unit may be installed.
    The unique method of supporting the gyrosphere by means of mere buoyancy
    ensures North stabilization during short power failures. E.g., after a three
    minute loss of power, no more than two degrees of deviation may be expected.
    Once power has been restored, the gyrocompass will return quickly to the cor-
    rect heading. The combined effects of the twin rotors and the liquid damping
    system virtually eliminate latitude error.
    Heading is measured as a 13-bit absolute value with a digital shaft encoder. The
    high-speed follow-up system (follow-up speed upto 100%s) ensures that accu-
    rate heading and rate of turn data is provided under all operating conditions.
    Integrated monitoring of the supply powers, gyroscope current and the follow-
    up system ensure secure and trouble-free operation.

    Data and Signal Interfaces

    The NAVIGAT XMK2 provides input interfaces for a magnetic compass (flux-
    gate sensor or electronic compass), speed log and position receiver.
    The system provides four serial data outputs to analogue or digital repeaters
    (including short-circuit-proof 24 VDC repeater power supply), two RS422 sen-
    sor data outputs, a Fast output interface (reduced dataset) and a Superfast out-
    put interface (adjustable baudrate, max. 38400 baud).
    Furthermore, a Furuno AD10 heading output, a 6 step/0 heading output, and an
    analogue rate of turn output are provided. One sensor data output may be con-
    figured to produce a graphical heading printout in conjunction with the nav.
    data printer NAVIPRINT.
    The NAVIGATXMK 2 may also be used as part of a component multicompass
    system in conjunction with the Compass Monitor NAVITWIN III and a Switch-
    Over Unit. In such a system, the Compass Monitor acts as the main heading
    source selector and controls distribution of the compasses' output signals via
    the Switch-Over Unit.

    ABOUT CMZ-900 GYROCOMPASS

    GENERAL

    A gyrocompass detectes the true north by means of a fast-spinning rotor, which is suspended with no friction
    and is influenced by gravity and rotation of the Earth. A gyrocompass consequently indicaes ship’s heading.
    CMZ900 series has been type approved in accordance with International Maritime Organization (IMO)
    standarts.

    FEATURES

    1) A modular design saves the space. Master compass can be integrated in the autopilot steering stand.

    2) Manual speed error correction.
     

    3) External heading sensor can back up the heading outputs.
     

    4) Serial data output IEC 61162-2 (high-speed transmission)
     

    5) A unique anti-vibration mechanism enhanced by the velocity damping effect of high viscous oil, provides
    superior damping of vibration and decoupling of shock at sea.

     

    6) A small and lightweight container enchances the follow up speed. The gyrocompass reading changes
    smoothly and does not lag when a small ship rapidly changes course.

     

    7) Easy maintenance and long maintance periods.
    - Titanium capsule and electrodes are employed at lower hemisphere of Gyrosphere. Purity is maintained
    inside of the container, and maintance invertal is then longer-dated.
    - The container id divided into two pieces at bottom when overhauled. Ship’s crew can replace Gyrosphere in
    case of emergency.

     

    8) The restart time can be preset from 1 to 99 hours.

    standarts.

    FEATURES

    1) A modular design saves the space. Master compass can be integrated in the autopilot steering stand.

    2) Manual speed error correction.
     

    3) External heading sensor can back up the heading outputs.
     

    4) Serial data output IEC 61162-2 (high-speed transmission)
     

    5) A unique anti-vibration mechanism enhanced by the velocity damping effect of high viscous oil, provides
    superior damping of vibration and decoupling of shock at sea.

     

    6) A small and lightweight container enchances the follow up speed. The gyrocompass reading changes
    smoothly and does not lag when a small ship rapidly changes course.

     

    7) Easy maintenance and long maintance periods.
    - Titanium capsule and electrodes are employed at lower hemisphere of Gyrosphere. Purity is maintained
    inside of the container, and maintance invertal is then longer-dated.
    - The container id divided into two pieces at bottom when overhauled. Ship’s crew can replace Gyrosphere in
    case of emergency.

     

    8) The restart time can be preset from 1 to 99 hours.
