Gyro Compass and INS

A new family of products with motion sensing and gyro compass functionality is introduced. The first product in this family is the MGC R3 which includes three Ring Laser Gyros and three linear accelerometers. Typical applications will output heading, roll, pitch and heave accurately.

Advanced Marine Technology

The MGC R3 product is a fully inertial navigation system (INS). It can output heading, roll, pitch, heave, position, acceleration, and velocity of linear motions, as well as angular rates. The unit is suitable for high precision maritime applications such as offshore operations and seabed mapping. It includes integrated navigation algorithms with input from a GNSS receiver for output of aided position and heading data.

Optimized for Accuracy and Performance

Proven PFreeHeave algorithms are part of the MGC R3 navigation algorithms that enable down to 2 cm accuracy in delayed heave output and 5 cm accuracy in real-time heave output. The MGC R3 outputs both processed and raw (gyro and accelerometer) sensor data and comes with Windows based configuration and data presentation software, the MRC+. This enhanced technology allows the delivery of precise high output data rates (200 Hz) and the management of relative (dynamic) heave position, velocity, and acceleration.
