Gyro Compass for ships / high-speed crafts - MGC R3
The MGC is a strap-down based gyro compass including three Ring Laser Gyros (RLG) and three linear accelerometers. The system can operate in Attitude and Heading Reference System (AHRS) mode and Inertial Navigation mode. In the AHRS mode input of speed and latitude data (VBW/VTG and GGA/GLL) is required.
External time input is also required (ZDA). In this mode the system will output heading, roll, pitch and heave. In the Inertial Navigation mode input of latitude, longitude, height and time (GGA and ZDA) and PPS from a GNSS receiver is required. In this mode the product will output heading, roll, pitch, heave and position.
The system is delivered with Windows based configuration software, MRC+. In this software the user selects output formats on the different communication lines in addition to other configuration purposes.
Digital I/O protocols
MGC data is available through both Ethernet interface and serial lines enabling easy distribution of data to multiple users on board the vessel. Output protocols for commonly used equipment are available on five individually configurable serial lines and five Ethernet/UDP ports.
- No rotational or mechanical wear-out parts
- 0.08° heading accuracy with GNSS aiding
- Outputs on RS-232, RS-422 and Ethernet
- High output data rate (200 Hz).
- Small size, light weight and low power consumption
