Simrad HS75 User Manual

Introduction
Overview
The HS75 GNSS Compass supports GPS, GLONASS, Galileo, QZSS, and BeiDou satellites.
The HS75 GNSS antennas are separated by 20 cm (7.87”) between phase centers, resulting in a
heading performance of better than 0.75° RMS. The HS75 can provide heading and positioning
updates at 10 Hz and delivers positioning accuracy of 0.6 m 95% of the time when using differential
GPS corrections from Satellite Based Augmentation Systems (SBAS).
The HS75 houses the following:
Dual GNSS, multipath-resistant antennas
Six-axis rate sensor (gyro)
GNSS receivers and processors
Standard NMEA 2000 Micro-C port for power and data
The six-axis rate sensor improves system performance and provides backup heading information in
the event a GNSS heading is not available due to signal blockage. The sensor provides a substitute
heading, accurate to within 1º per minute for up to three minutes.
