06/27/10 — A new family of Attitude Heading Reference Systems (AHRS) from Yost Engineering, the low-cost, compact YEI 3-Space Sensors, are now available at under $150. The YEI 3-Space Sensor family provides a reliable, high-accuracy, low-cost, small-size solution to movement and orientation challenges. The YEI 3-Space Sensor utilizes on-board processing and filtering algorithms to provide exceptionally accurate attitude and heading information based on the three-axis accelerometer, three-axis gyroscope, and three-axis compass. Orientation can be returned in absolute terms or relative to a designated reference position. The proprietary multi-reference vector mode increases accuracy and greatly reduces and compensates for sensor error. The YEI…
