HS70 GPS Compass

SKU: 000-10453-001

The HS70 is a reliable source of heading and position data for Simrad navigation systems, autopilots, and other equipment. This commercial-grade GPS compass is ideal for larger offshore powerboats. The HS70 delivers enhanced accuracy and update speed compared with the ultra-compact HS60, while still featuring a compact and easy-to-install design.

Product details

Accurate Heading with Dual GPS Antennas
An accurate heading sensor is essential for autopilot, advanced radar features, and many other on-board electronics. The HS70 GPS compass determines your boat’s heading using two separate GPS antennas, packed into one compact casing. The commercial-grade HS70 offers heading accuracy to within 0.75 degrees: much greater than a common magnetic rate compass, without the cost and maintenance of a gyrocompass. Unlike a standard GPS receiver, which can only estimate heading based on the movement of your boat, the HS70’s dual antennas provide an accurate heading even while your boat is stationary. Integrated gyro and tilt sensors offer enhanced performance, and provide a temporary source of heading data during any loss of GPS signal.

Fast and Accurate Positioning
The HS70’s high-speed GPS receiver calculates your position up to 20 times every second, perfect for fast-moving powerboats and equipment that relies on high-speed position updates. Quick startup means you won’t get caught waiting for a position fix before you can get underway. Support for satellite based augmentation systems (SBAS) offers enhanced positional accuracy where available.

Rate of Turn, Heave, Pitch, and Roll
The HS70 also calculates your boat’s rate of turn, heave, pitch, and roll. Rate of turn is essential for optimal autopilot performance, while heave data is used by some sonar equipment to compensate for the effects of wave action. This additional data is output to compatible equipment over your boat’s NMEA 2000® network, or via an NMEA 0183® connection (rate of turn and heave only).
