Inertial measurement unit of waverider buoy. Development and test results

Resumo

The paper focuses on development and studies of inertial measurement unit of a waverider buoy based on MEMS sensors. The model for estimating the accuracy of IMU algorithms is developed and studied, selection of time constants for orientation system and the vertical channel is validated, error in the wave elevation is estimated. The bench tests of IMU produced based on the results of these studies have confirmed the obtained conclusions and the error level.
