Cruizcore®R6081U A digital gyroscope and accelerometer module for measuring angular rate, heading angle (also known as directional or yaw) and acceleration under dynamic conditions. This is a highly compact, lightweight, fully self-contained device. R6081U with an internal MEMS gyroscope 3-axis accelerometer, an internal voltage regulator, The signal processing circuit / AD converter and the RISC microprocessor .R6081U running our patented error correction algorithm use adaptive reduced order Kalman filters to reduce the errors that affect this sensor (i.e. bias drift, scale factor, etc.) So it can output very precise and stable angular velocity and heading angle. The startup time is less than 1 second and is used to calculate the bias parameters, after which no further calibration is required. R6081U is the best solution for uniaxial navigation rate measurement.
