Satellite Compass

GC901 provides a high system accuracy for the heading of the ship, 0.4°
Provides highly accurate heading data for Autopilot, Radar, ARPA, Scanning Sonar, Current Indicator, Chart Plotter, ECDIS and Autopilot.

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 performance; Built-in high-precision inertial navigation module, when the satellite navigation signal is weak or temporarily lost, the heading can keep 1min of compensation output without interruption; It has the characteristics of fast start, signal recapture, heading update up to 20 times per second, and can operate at a continuous turning rate of up to 90° per second; The display instrument is light-weight design, partial to installation, and multiple display modes are available; Compared with gyro compass, basically no maintenance;Multi-channel standard NMEA0183 output, which can be connected to multiple different navigation systems such as radar and AIS.

 

We have produced a relatively high-end marine gps satellite compass, why is it high-end?

Data filtering has always been our strong point. GPS speed and heading stability has been around for many years in our company.

In data stabilization, data filtering should be very experienced for us.

The orientation of our GNSS compass is fast, and it is not easy to lose lock in bumps and high-speed corners.

We currently exclusively use pre-carrier phase technology. Only pre-decoding can solve these problems, and the data is more accurate.  The data delay is small, the real-time performance is good, and the orientation is fast.

All GPS compasses in the market are processed by the post-CPU algorithm of GPS positioning signals, but our GPS compass is different, and we are the only one that uses pre-signal processing.

What is pre-signal processing?

The filtering algorithm is processed before GPS signal positioning. In this way, the positioning accuracy is very high and more accurate, this is the essential difference.

Built-in gyro compensation system has better performance;

Built-in high-precision inertial navigation module, when the satellite navigation signal is weak or temporarily lost, the heading can keep 3min of compensation output without interruption;

It has the characteristics of fast start, signal recapture, heading update up to 20 times per second, and can operate at a continuous turning rate of up to 90° per second;

The display instrument is light-weight design, partial to installation, and multiple display modes are available;
Compared with gyro compass, basically no maintenance;
