DEVICE: GYROCOMPASS

BRAND: SPERRY MARINE / C-PLATH

TYPE: NAVIGAT X MK2

SPERRY MARINE NAVIGAT X MK2 GYROCOMPASS

Description & Key Features
The NAVIGAT X MK2 is a microprocessor-controlled gyrocompass system with integrated automatic North speed error correction. Its single-unit design, housed in a durable polyurethane hard foam casing, allows installation on any bridge. An optional remote operating unit can also be installed if required.

A unique buoyancy-supported gyrosphere ensures North stabilization during short power failures. For example, after a three-minute power loss, the maximum deviation is under 2°. Once power is restored, the system quickly returns to the correct heading. Twin rotors combined with liquid damping effectively eliminate latitude errors.

Heading is measured as a 13-bit absolute value via a digital shaft encoder. High-speed follow-up (up to 100°/s) ensures accurate heading and rate of turn data under all conditions. Integrated monitoring of power supply, gyroscope current, and follow-up system guarantees reliable operation.
