Compact inertial sensors from silicon sensing vital to Mayflower Autonomous voyage

By GeoConnexion - 12th April 2022 - 13:36

The Mayflower Autonomous Ship (MAS) is set to re-embark on its three-week trans-Atlantic journey in April 2022 equipped with two Silicon Sensing’s AMU30 inertial measurement units (IMUs). These Silicon Sensing AMU30 devices send highly precise motion data to the new ‘AI captain’ that guides the vessel. They also assist in measuring sea surface height as part of detailed scientific analysis of ocean topography. AMU30 is a micro electro-mechanical system (MEMS) unit with impressive inertial performance, including exceptional bias stability and low noise characteristics, plus an embedded Kalman Filter based AHRS (attitude and heading reference system) algorithm. It delivers precise 3-axis outputs of angular rate and acceleration, plus roll, pitch and heading angles, altitude and pressure, and temperature, at 200Hz – all critical to precise maritime navigation.
