  • Page 6: 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...

    (A) on the underside of the housing. Make sure that any transmitting antennas are mounted away from the HS75 by at least 2 m (6.5 ft) to ensure tracking performance is not compromised. Refer to the documentation supplied with the transmitting antenna for minimum safe distances.

  • Page 8: Mounting Orientation

    C Minimum cable separation: 0.3 m (1 ft) for the first 5 m (16.5 ft). Mounting orientation Mount the HS75 parallel to, and along the centerline of the axis of the boat. Doing so, provides a true heading. The recessed arrow (A) under the antenna housing should point towards the bow of the vessel.
  • Page 9 1 Use the supplied mounting template to mark and drill the required holes for the screws and the cable. 2 Place the HS75 over the mounting holes and insert the mounting screws (M8) through the bottom of the mounting surface into the HS75.
  • Page 10 4 Connect the NMEA 2000 drop cable to the HS75 and place the HS75 assembly into the lower adapter so that the four latches snap into place. ¼ Note: To remove the HS75, press in the clips on one side, at which point the HS75 can easily be removed.
