Kongsberg MGC® COMPAS R-series

Type approved compass for ships and high-speed crafts

The MGC® COMPASS system is IMO type approved as a gyro

compass for navigation purposes for use together with a heading

and bearing repeater. Very high reliability is achieved by using

Ring Laser Gyros with no rotational or mechanical wear-out parts.

Typical applications

The system can be operated as an inertial navigation system as

well as a gyro compass with output of position and heading.

Linear position and velocity measurements can then be output in

up to four different points on the vessel.

Function

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 configuration software. 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 eight individually configurable serial lines and three

Ethernet/UDP LANs.
