The Racelogic IMU houses three MEMs Yaw rate sensors, and three MEMs G-sensors. The Yaw sensor can measure ±150º/s, and the accelerometers can measure ±1.7g. The maximum sample rate of the IMU is 100Hz, and the sensor connects directly to a VBOXII or VBOXIII to measure Pitch rate, Roll rate, Yaw rate, Longitudinal accel, Lateral accel and Vertical accel. The difference between a good IMU and a bad one is the quality of the temperature calibration process. To obtain the best results, we have invested in a state of the art environmental chamber, and installed a precision stabilised turntable. We calibrate using 12 different temperature steps, and have carefully optimised the process for all three axes to take 3 hours, resulting in a very stable sensor. In the final product, the sensors are oversampled at 500Hz to reduce noise, and the internal A-D on each channel is 24 bits.  Furthermore, the IMU is now constructed with a splash-proof casing which is rated to a limited ingress IP rating of IP65, making it ideal for use on boats or in harsh environments. This sensor can be used either directly connected to a VBOX, or it can also be used as a stand alone device, with the CAN output fully configurable by the end user.
