INTRODUCTION 1. INTRODUCTION 1.1 HS50 System components Simrad HS50 is a GPS compass that provides true heading output with position, velocity and rate of turn information in addition. This product replaces several vessel instruments with one compact navigation package: gyrocompass, GPS system, speed log and Rate Of Turn (ROT) indicator. The HS50 comprises the following units: SENSOR UNIT 1m DISPLAY UNIT 30m 15m PROCESSING UNIT POWER INPUT The Sensor unit contains two GPS sens

Simrad HS50 Heading Sensor High-precision heading is derived from the fixed-distance dual GPS antenna arrangement in the Sensor unit, using carrier phase data to generate heading information independent of latitude and vessel dynamics. GPS position and speed are calculated from both antennas, which give redundant position and velocity sources in this product. DGPS signals may be input to the HS50 to improve position and velocity accuracy, but has no impact on the heading accuracy. Refer

Simrad HS50 Heading Sensor 3.4 Sensor unit Location of the unit The Sensor unit is the most important part of the HS50 system, and great care should be taken when deciding the mounting location. The space above the Sensor unit has to be free of obstructions of any kind. A GPS compass is more sensitive for blocking and reflections (multipath) of GPS signals than GPS sensors that are only used for calculating position. This since HS50 also utilizes carrier phase measurements for heading
