Introduction
Overview
The HS70 is a complete GPS compass and positioning system in a single enclosure that
requires only one power/data cable connection. With its NMEA 2000 and NMEA 0183 support
and ease of installation, the HS70 is the perfect solution for marine applications.
The HS70 is an integrated system that houses the following:
• Dual integrated GPS antennas
• Power supply
• Single axis gyro
• Tilt sensor on each axis (X and Y axes)
• Standard NMEA 2000 port (cable to be ordered separately)
• Standard NMEA 0183 port (cable to be ordered separately)
The gyro and tilt sensors are present to improve system performance and to provide backup
heading information in the event that a GPS heading is not available due to signal blockage.
The HS70’s GPS antennas are separated by 27.5 cm between their phase centers, resulting
in better than 0.75° rms heading performance. The HS70 provides heading and positioning
updates of up to 20 Hz and delivers positioning accuracy of better than 1.0 m 95% of the time
when using differential GPS corrections from Space Based Augmentation Systems (SBAS).
