In my project I use the sensor ADIS16480 to determine the pitch and roll during movement of a car. I need to know a value of an angle accurate to 1 degree. At the moment I use Euler Angles. The settings of the sensor are used by default . While I move the sensor on a plane surface I can see, that the value of the angle is 5 degrees, and when I move the sensor circle-wise during 3-4 seconds, the value can be changed to 15 degrees. I think, it`s an error of the sensor, because the value of an angle must not exceed 0.3 degree. An application of AVERAGING/DECIMATION FILTER was useless ( the magnitudes DEC_RATE = 245 and 2047 were used)
What must be done to obtain an essential value of pitch and roll on conditions that a car is moving and the frequency of an inquiry of the sensor is 10 hz.
