    Overview:

    The Sperry Navigat X MK 2 digital marine gyrocompass is the new-generation advanced marine gyro compass system that meets modern navigation and ship control technology demands. It is designed with strap down technology for integrated bridges and high-speed vessels.

    The NAVIGAT X MK 2 marine gyro compass provides highly accurate and reliable heading information in even extreme marine environments.

    It provides accurate North-speed error-corrected true heading as well as rate-of-turn data under all operating conditions, moreover it is a cost-effective solution for all international carriage requirements.

    The NAVIGAT X MK 2 gyrocompass is a Compact modular design and 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 gyrocompass provides better than 40,000 hours mean time between failures. The system remains north-stabilized even during short power interrupts of up to 3 minutes.

    The NAVIGAT X MK 2 complies with 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 typeapproved by Germanischer Lloyd (GL) in accordance with the Marine Equipment Directive (MED) 96/98/EC.

    Features:

    • Easy to install and easy to service with short maintenance and repair times
    • Comprises one single unit
    • Monitoring and alarm functions for all voltages, gyroscope current and follow-up system.
    • Permanent storage of operational data (gyrosphere current, temperature, elapsed operation time).
    • Self-aligning repeater compasses with serial interface IEC-61162-1 / RS 422
    • Complies with IMO regulations A.424(IX), A.694(17), A.821(19): high-speed craft (HSC) and ISO 8728
    • Power supply: two independent 24 VDC inputs
    • Control and display unit (not removable) in front cover with 4-digit heading display and 6 operating keys
    • Automatic static north speed error correction – no extra unit required
    • Highly accurate heading data transmission by means of shaft encoder
    • Gyro system remains north-stabilized during power interruptions within the required accuracy
    • Twin rotors (19,000 rev./min.) and liquid damping system eliminate latitude error
    • Monitoring and alarm functions for all voltages, gyroscope current and followup system
    • Short maintenance and repair times – low service costs
