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.
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.
