Product Introduction
GPS compass, Standard NMEA0183 output, providing high-stability, high-precision ship heading data and positioning data for Radar, ARPA, ECDIS, AIS, Chart Plotter, Autopilot, Sonar and other marine navigation equipment
Product Introduction
The GNSS gps compass is a cost-effective all- in-one GNSS/INS navigation and heading solution. It provides accurate dual antenna GPS based heading that is not subject to magnetic interference.
It features high accuracy RTK positioning and is plug and play with NMEA 0183, NMEA 2000 and Ethernet interfaces.
Almost all manufacturers adopt post RTK technology, only us adopts front RTK technology.
So under the same number of satellites and signal strength, the front RTK technology has better accuracy, stronger real-time performance, and faster orientation than the post RTK technology.
Product Feature
● Pre-type carrier phase decoding technology, more precise orientation;
Beidou/GPS dual-star system with faster directional speed;
● Advanced speed and course filtering technology to make the data more stable; Built-in gyro compensation system has better heading performance;
● It has the characteristics of fast start, signal recapture, fast heading update, and high turning rate
● Excellent industrial product design, stylish appearance, easy installation;
● Maintenance free and no recurring cost as there are no mechanical parts.

Installation
a)The satellite compass antenna is recommended to be installed at the highest position on the ship, without any obstructions in the satellite signal receiving surface;
b)Stay away from any metal surface or magnetic surface that can reflect satellite signals. This reflection may lead to signal "multipath" to a certain extent, thereby reducing the heading performance and accuracy of the compass;With the compass as the center, there should be no metal surface above the horizontal plane of the fuselage within a radius of 2m;
c)Install away from radio frequency radiation sources to avoid RF radio frequency interference. If there are radar systems, satellite stations, etc., ensure that the antenna is installed outside the range of the radar radiation beam.
