The Marine Data MD97CSP is a compact, marinised Compass Sensor Processor manufactured in the United Kingdom by Marine Data Systems Ltd. Supplied as the core signal-processing component within Marine Data Transmitting Heading Device (THD) systems—including both Transmitting Magnetic Compass (TMC) and Electromagnetic Compass (EMC) configurations—the MD97CSP digitizes raw analog fluxgate signals into accurate NMEA 0183 heading data.

The unit interfaces directly with either the MD52A/B ship’s magnetic compass pick-off sensor (for TMC installations) or the MD53A/B Earth’s field electromagnetic fluxgate sensor (for EMC installations). It executes fundamental fluxgate calibration calculations, stores magnetic deviation and variation parameters in non-volatile memory, and transmits digital heading data via dual NMEA 0183 channels or a dedicated CAN Bus link to an MD71THD Control and Display Unit.

Key Features:
• Dual Sensor Architecture Compatibility: Processes signals from either the MD52A/B magnetic compass sensor (TMC) or the MD53A/B electromagnetic fluxgate sensor (EMC).
• Non-Volatile Calibration Storage: Performs fluxgate calibration calculations and retains magnetic deviation and variation parameters in non-volatile memory.
• Dual NMEA 0183 & CAN Bus Connectivity: Outputs digital NMEA 0183 heading data ($HDT, $HDG, $HDM) across two channels and communicates with the MD71THD Display Head via a dedicated CAN Bus interface.
• Rugged Marinised Enclosure: Built into a compact, waterproof housing designed for installation near the vessel’s magnetic compass binnacle or bridge equipment locker.
• Modular THD System Integration: Operates either standalone within an MD97TMC system or paired with the MD71THD head unit in advanced MD71TMC / MD71EMC systems.
