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
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.
