The NAVITRON NT990HDI is a robust and reliable Heading Data Interface designed to seamlessly integrate high-precision heading information from your vessel’s gyrocompass or satellite compass into modern marine networks. It acts as the essential translator, converting proprietary heading data into universal NMEA 2000 and NMEA 0183 formats, ensuring your radar, ECDIS, autopilot, and other critical displays receive accurate, real-time course information.
Ideal for commercial vessels, workboats, and serious mariners, the NT990HDI ensures your navigation suite operates as a unified, dependable system.
Key Features & Benefits:
- Professional Data Bridging:Â Converts heading data from high-performance sensors (like JRC, Tokimek, Simrad, Furuno, and others) to standard NMEA outputs for universal compatibility.
- Dual Output Standards: Provides both NMEA 2000 (plug-and-play connectivity) and NMEA 0183 (versatile serial connection) for maximum integration flexibility with new and existing equipment.
- Enhanced Situational Awareness:Â Delivers precise heading data to stabilize Radar/ARPA images, enable true-motion on ECDIS, and ensure accurate course-keeping with the autopilot.
