~The YEI *-Space Sensor™ Watertight USB/RS**2 is a miniature, high-precision, high-reliability, Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU) offering USB 2.0 and RS**2 communication interfaces in a single low-cost end-use-ready IP*7 sealed case. The Attitude and Heading Reference System (AHRS) uses triaxial gyroscope, accelerometer, and compass sensors in conjunction with advanced processing and on-board quaternion-based Kalman filtering algorithms to determine orientation relative to an absolute reference in real-time.
Orientation can be returned in absolute terms or relative to a designated reference orientation. The proprietary multireference vector mode and **-point ortho-calibration process increase accuracy and greatly reduce and compensate for sensor error. The YEI *-Space Sensor system also utilizes a dynamic sensor confidence algorithm that ensures optimal accuracy and precision across a wide range of operating conditions.
The YEI *-Space Sensor Watertight USB/RS**2 unit's features are accessible via a well-documented open communication protocol that allows access to all available sensor data and configuration parameters using either USB 2.0 or RS**2. Versatile commands allow access to raw sensor data, normalized sensor data, and filtered absolute and relative orientation outputs in multiple formats including: quaternion, Euler angles (pitch/roll/yaw), rotation matrix, axis angle, two vector(forward/up).
