Simrad HS70 Compass


The Simrad HS70 brings a series of new features to a traditional heading sensor including heave, rate of turn, pitch and roll output.


The HS70 uses SBAS (WAAS, EGNOS, MSAS, etc.) for differential GPS positioning providing a low cost, yet highly effective heading and position based smart antenna. The HS70 delivers extremely time-to-first-fix, and excellent in-band and out-of-band interference rejection.


  • Provides heading, positioning, heave, rate of turn, roll and pitch
  • SimNet, NMEA2000 or NMEA0183 communication
  • 0.75 degree heading accuracy in amazingly small form factor
  • Differential positioning accuracy of 1.0 m, 95% of the time
  • SBAS compatible (WAAS, EGNOS, MSAS, etc.)
  • COAST technology (with integrated gyro and tilt sensors) maintains differentially-corrected positioning for 40 minutes after loss of differential signal.
