Gyro Compass and INS

A new family of products with motion sensing and gyro compass functionality is introduced. This MGC R5 product, with emphasis on position drift, includes three Ring Laser Gyros and three linear accelerometers.

Advanced Navigation Capabilities

The MGC R5 product is a fully inertial navigation system (INS). It can output heading, roll, pitch, heave, and position. Acceleration and velocity of linear motions, as well as angular rates, are output from the unit. The MGC R5 product outputs both processed and raw (gyro and accelerometer) sensor data. With integrated navigation algorithms that incorporate input from a GNSS receiver, the product delivers output of aided position and heading data.

Optimal Performance for Maritime Applications

Designed for high precision maritime applications such as offshore operations and seabed mapping, the MGC R5 excels in variable environments. It supports various modes, including Gyrocompass mode, which requires only the input of speed to deliver accurate heading, roll, pitch, and heave, and Integrated Navigation mode, which leverages additional inputs from a GNSS receiver for comprehensive navigation data.
