Gyrocompass · Position & Heading
Sperry Marine MK37 is a gyrocompass. It is installed on the bridge and/or at the associated sensor location, with outputs distributed to other navigation equipment as required. Its purpose is to provide the vessel navigation parameter indicated by the equipment category for bridge use and connected systems. Sensor principle, correction methods, interfaces and redundancy depend on the exact model and vessel installation. The exact model designation identifies sensing technology, interfaces and accuracy class; these characteristics must be confirmed from the approved manufacturer documentation.

What our service work and the manufacturer documentation say about keeping this model running.
Compare the indicated value with independent references and investigate persistent disagreement rather than applying unrecorded corrections. Inspect sensors, antennas, cabling, power supplies, repeaters and network interfaces applicable to the installed equipment. Verify alarms and data outputs to radar, ECDIS, autopilot and voyage-data systems where connected. Keep calibration, deviation or configuration records current as appropriate to the sensor type. Protect exposed sensors from paint, deposits and water ingress. Refer to manufacturer and bridge-equipment documentation for exact test, calibration and alignment procedures.
Keep fuses, lamps or display consumables, selected power-supply and interface modules, cables or connectors and manufacturer-recommended sensor service parts. Replacement core sensors or processors must remain compatible with the approved bridge installation. Preserve calibration and configuration data when changing equipment.
