Accurate heading and position data for Simrad chartplotters, autopilots, radar, and AIS. Ideal where precise heading data is essential, such as autopilot systems, it provides an all-in-one alternative to a separate compass and GPS receiver. On-board gyro and tilt sensors deliver heave, roll, and pitch information to compatible systems. These sensors also offer faster and smoother heading updates than GPS alone, and provide heading updates during any temporary loss of GPS signal.
