GPS Compass Hemisphere V113 is a complete GPS and GLONASS compass system for heading and positioning in one device that only requires one power/data cable connection. V113 has no mechanical parts such as gimbals, rotary motors, so it is free from routine maintenance. Because the heading is taken from GNSS, there is no need for settling time, gyrocompass calibration, and speed correction. The Vector Performance of V113 which is not affected by the earth's magnetic field (geomagnetism) and the easy installation process makes V113 the right solution for various marine applications such as Radar/ARPA, ECDIS, Sonar, Pemerum Pluma, and so on.
Operating Principle
The GPS Compass Hemisphere V113 system uses a high-performance GNSS receiver and 2 antennas to process satellite signals to obtain accurate and reliable position and direction/heading information at a high update rate. One antenna is designed as a primary GNSS antenna and the other as a secondary GNSS antenna. Position data is obtained by calculation referenced to the phase center of the primary GNSS antenna, while heading data is calculated using a vector reference formed from the phase center of the primary to the secondary GNSS antenna. The GNSS receiver uses a complex algorithm by combining satellite locations and distances to each satellite to obtain geographic location and heading. The receiver uses 4 or more GNSS signals to perform calculations to obtain valid three-dimensional coordinates and heading.
