Introduction

Overview

The HS60™ GPS Compass is based upon SIMRAD's new GPS techno-
logy. It is a complete GPS compass and position system in a single
enclosure that connects via a standard NMEA 2000 cable. With
NMEA 2000 support and ease of installation, the HS60 is the perfect
solution for marine-based applications.
The HS60 is an integrated system that houses the following:
• Vector II technology
• Dual integrated GPS antennas
• Power supply
• Single axis gyro
• Tilt sensor on each axis (X and Y axes)
The gyro and tilt sensors are present to improve system perfor-
mance and to provide backup heading information in the event
that a GPS heading is not available due to signal blockage.
Vector II technology supports multiple RF front ends - enabling
tighter coupling of measurements from separate antennas for use
in heading-based products. Users will achieve excellent accuracy
and stability due to it's more accurate code phase measurements,
improved multi- path mitigation, and fewer components.
The HS60's GPS antennas are separated by 13.5 cm between their
phase centers, resulting in better than 2° rms heading performance.
The HS60 provides heading and position updates of up to 10 Hz
and delivers position accuracy of better than 1.0 m 95% of the time
when using differential GPS corrections from Space Based Augmen-
tation Systems (SBAS).
The HS60 also features exclusive COAST™ technology that enables
SIMRAD GPS receivers to utilize old differential GPS correction data
for 40 minutes or more without significantly affecting the position
quality. The HS60 is less likely to be affected by differential signal
outages due to signal blockages, weak signals, or interference when
using COAST.
