The Yost Labs 3-Space™ Sensor Watertight USB/RS232 is a miniature, high-precision, high-reliability, Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU) offering USB 2.0 and RS232 communication interfaces in a single low-cost end-use-ready IP67 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 orientation 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 gradient descent calibration process and high update rates increase accuracy and greatly reduce and compensate for sensor error. The Yost Labs 3-Space™ Sensor system also utilizes a dynamic sensor confidence algorithm that ensures optimal accuracy and precision across a wide range of operating conditions.
The Yost Labs 3-Space™ Sensor Watertight USB/RS232 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 RS232. 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).
