Overview

The Simrad 000-16143-001 is a multi-GNSS compass sensor that feeds stable heading and position data to your NMEA 2000 network for systems that need a clean heading source.

It tracks GPS, GLONASS, Galileo, BeiDou, and QZSS and reports heading at 0.75 degrees RMS, including when the boat is sitting still. Heading and position updates are available up to 10 Hz, and with SBAS corrections available it is specified at 0.6 m positioning accuracy (95%).

Power and data run through a single NMEA 2000 Micro-C connection. The unit is rated IPX7, runs on 6 to 36 VDC for 12 V or 24 V systems, and measures 158 x 74 x 348 mm.

Key features

• 0.75 degrees RMS heading performance with GNSS-based heading that does not depend on boat movement
• Multi-constellation reception: GPS, GLONASS, Galileo, BeiDou, and QZSS
• Integrated gyro aiding to help smooth heading output and bridge brief satellite dropouts
• Up to 10 Hz updates for heading and position for responsive steering on compatible equipment
• NMEA 2000 (Micro-C) interface for power and data on a standard backbone
• Outputs heading and rate of turn, plus motion data such as heave, pitch, and roll for compatible systems
• 6 to 36 VDC input with typical 3.2 W consumption
• IPX7 water resistance, 95% non-condensing humidity rating, and -40 C to +70 C operating range
• Surface or pole mounting options; about 0.75 kg weight

Installation and setup

Mount the HS75 where it has a clear view of the sky and a stable base, using either a flat surface or a pole mount. Keep it away from structures and onboard gear that can block satellites, and route network cabling away from high-current runs where practical.

The specified compass-safe distance is 50 cm (19.7 in), so plan placement accordingly if you have a magnetic compass or other sensitive instruments nearby.

Network and system integration

On a NMEA 2000 backbone, the sensor shares heading, GNSS position, COG and SOG, and rate-of-turn information with connected displays, autopilots, and radar systems that rely on heading data. Because it draws power from the network and accepts 6 to 36 VDC, it fits both 12 V and 24 V installations as long as the backbone is powered and properly terminated.

Use on board

This sensor is a good fit when an autopilot needs a steady heading and rate-of-turn feed, or when a radar and chart system needs heading data that stays accurate at low speed and while stationary. It also suits boats where you want a single NMEA 2000 source for both heading and GNSS position without adding separate sensors.
