Sperry Navigat MK2 Digital Gyrocompass System.

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, and the NAVISTAR satellite compass.
