The XG1010 is a fully self-contained MEMS digital gyroscope evaluation kit. This device provides communication interfaces that facilitate its use with PCs. The XG1010 can be used either as the evaluation kit or as a stand-alone sensor. The XG1010 has USB communication interfaces. The XG1010 is a compact, low-cost yet very accurate sensing solution. The XG1010 uses MEMS sensors resulting in low-cost and high reliability. The XG1010 has a 50 Hz bandwidth and can measure rates up to ± 150 °/sec. The XG1010 minimizes the sensor error with the help of an adaptive reduced Kalman filter. The expected error contributed by drift is less than 10 °/h and the scale-factor is accurate within 0.5% of the scale factor. The XG1010 start-up time is less than one second and it does not require further calibration thereafter. The XG1010 includes a monitoring program that allows testing the different sensor settings and operational modes. Because of its small size and low power consumption the XG1010 is suitable for applications that require direction estimation such as mobile devices and robots.
