An accurate heading sensor is essential for autopilot, advanced radar features, and many other on-board electronics. The commercial-grade HS75 offers heading accuracy to within 0.75 degrees, significantly greater than a common magnetic compass, without the cost and maintenance of a gyrocompass.
Unlike a standard GPS receiver, which estimates heading based on boat movement, the HS75 provides accurate heading even when the boat is stationary. The HS75’s high-speed GPS receiver calculates position up to 20 times per second, perfect for fast-moving powerboats and equipment requiring high-speed updates. Quick startup ensures you are not delayed waiting for a position fix, and support for satellite-based augmentation systems (SBAS) offers enhanced positional accuracy where available. The HS75 also calculates rate of turn, heave, pitch, and roll, which are essential for optimal autopilot performance and sonar wave compensation. The unit features a simple plug-and-play installation with a small form factor, measuring only 35 cm in length for easy mounting on a flat surface or pole. The product reference is 000-16143-001 and weighs 0.75 kg.
Integrated gyro and tilt sensors offer enhanced performance and provide a temporary heading source during any loss of GPS signal.
This additional data is output to compatible equipment over the boat’s NMEA 2000 network.
