A maintenance-free alternative to a traditional separate compass and GPS antenna.The HS70 GPS Compass is a complete GPS compass and positioning system in a single enclosure that requires only one power/data cable connection. As an alternative to a traditional separate compass and GPS antenna, this combined sensor is maintenance free and incorporates many additional features.Provides heading data, just like a traditional compass, with no requirement for a separate GPS antenna. It calculates turn rates for precision heading and positioning while underway. Connects to an NSS, NSE or NSO navigation system with ease.Key FeaturesHeading Sensor: Provides heading data, just like a traditional compassGPS: No requirement for a separate GPS antenna; delivers an extremely fast fix and excellent in-band and out-of-band interference rejectionRate of Turn Sensor: This smart sensor calculates turn rates for precision heading and positioning while underwayIntegrated Gyro and Tilt Sensors: Deliver fast startup times and provide heading updates during temporary loss of GPS; COAS technology maintains differentially-corrected positioning for 40 minutes after loss of differential signalCompact Design: Measuring just 40cm, the HS70 is easily flush or pole mountedSBAS Compatible: WAAS, EGNOS, MSAS etc.Fully Waterproof: Certified to IEC 60945 standardNMEA 2000 Connectivity: Connect to an NSS, NSE or NSO navigation system with easeSpecifications Receiver Type: Two 12-channel, parallel tracking Data Interface: NMEA 0183, NMEA 2000 Voltage: 6 to 36V DC Amperage: 240mA @ 12V DC Dimensions: 9.95" W x 20" L x 6.77" H Weight: 3lb.
