The MRU is suitable for any maritime operation that requires attitude determination and motion compensation. Kongsberg's range of motion sensors provides high accuracy motion measurements in all dynamic environments. They cover all marine activities, from small hydrographic vessels to large vessels and installations.

Typical Applications:

  • Motion compensation of single and multi-beam echo sounders
  • Orientation and attitude measurements on AUVs and ROVs
  • High speed craft motion control and damping systems
  • Heave compensation of offshore cranes
  • Dynamic positioning
  • Hydro acoustic positioning
  • Ship motion monitoring
  • Ocean wave measurements
  • Antenna motion compensation and stabilization

Built with solid-state gyros and accelerometers, Kongsberg's MRUs provide realtime motion measurements with high dynamic accuracy. In-house, state-of-the-art design, construction and assembly provide an MRU with extremely high reliability in the most demanding marine environments.

Micro Electro Mechanical System (MEMS) -based gyros have been implemented in many different variations over the past 25 years and a constant focus on innovation and ingenuity has led to continous improvements in price/performance. Consequently, MEMS-based gyros today challenge the 'prone to wear' mechanical gyro solutions, as well as gyros based on fibre optic (FOG) technology. A gyro developed by KONGSBERG, optimized for use in the high-end of the Kongsberg Motion Reference Unit (MRU) product range, is a defining example of the MEMS-based gyro design, demonstrating new performance levels for this technology.
