The Yost Labs 3-Space™ Data Logger v3 GPS & BLE sensor combines a miniature, high-precision, high-reliability Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU) with a micro-SD card storage device and a rechargeable lithium-polymer battery solution into a single low-cost end-use-ready unit. The AHRS/IMU uses triaxial gyroscope, accelerometer, and magnetometer 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.
When attached to a USB 2.0 host, the 3-Space™ Data Logger v3 GPS & BLE sensor can enumerate as both a virtual COM port and a USB mass-storage device. The virtual COM port allows access to real-time sensor data, configuration parameters, and diagnostic tools, and the mass-storage device allows access to data capture options, sensor configuration options, and captured sensor data. Versatile commands provide for 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, and two vector (forward/up).
