Inertial Labs - Model MRU Series -Motion Reference Units
Inertial Labs has developed Motion Reference Units (MRU) to meet requirements from marine and hydrographic applications. MRU is enhanced, high-performance strapdown Motion Sensor, that determines Pitch & Roll, Heave, Sway, Surge, Accelerations, Angular rates, Heading, Velocity and Positions for any device on which it is mounted.
- ABS Certification, affordable price
- IP-67 sealed or Subsea version
- 5% / 5 cm Heave accuracy
- up to 0.01 deg Pitch and Roll accuracy
- 40 cm DGPS or 1 cm RTK position
- 0.03 m/sec Velocity accuracy
- 0.005 m/sec2 Acceleration accuracy
- 0.0002 deg/sec Angular rate accuracy
- NMEA 0183 and TSS1 output data format
- Kongsberg/Seatex, SMC & Teledyne data formats*
The Inertial Labs Motion Reference Units utilizes solid state 3-axes each of precision accelerometers, magnetometers, gyroscopes and barometric sensors to provide accurate Heave, Sway, Surge, Pitch and Roll of the device under measure.
Integration of very low noise gyroscopes output provides high frequency, real-time measurement of the Vessel, Ships, Helidecks, ROV, Marine antennas, Cranes rotation about all three rotational axes.
Through a combination of proven sector expertise and a continued investment in technological innovation, Inertial Labs delivers the optimum balance of price and performance ratio solutions for its customers.
