| Definition | A platform attitude sensor. For motion compensation of swath bathymetric echo sounders, DP systems, ROVs, helideck monitoring systems, high speed vessel motion damping systems and tow-fish systems. It is also used for structural monitoring of offshore platforms and large vessels. It comprises three highly accurate accelerometers and three Micro-Electro-Mechanical-Structures (MEMS) gyros of type MRG (MRU Rate Gyro). It uses solid state sensors with no rotational or mechanical wearout parts. It has a high output data rate (100 Hz) and offers 189 output variables. These variables can be either digital or analog output signals. Roll/pitch accuracy: 0.02 degrees RMS. Acceleration accuracy: 0.01 m/s RMS. Heave accuracy: 2 cm or 2 % (delayed-mode), 5 cm or 5 % (real-time). | |
