Dear Sir or Madam,
I am looking into using a gyroscope to assist in measuring a vehicle's pitch. I understand that a gyroscope will output the rate of change of pitch rather than absolute pitch angle and that the accuracy of the sensor heavily depends on the application.
The following is a scenario of the intended application:
1. Assume you have the vehicle's "exact" pitch at the start.
2. Switch on gyroscope, (now the vehicle's exact pitch is unknown).
3. Use gyroscope pitch angular rate to update (<0.2 Hz) vehicle's pitch.
Assuming the bias drift can be "eliminated" and the vehicle's pitch is limited to +/- 6 degrees, can any of the avialable gyroscopes be used to maintain an accuracy smaller than or equal to +/- 0.5 degree on the Vehicel's pitch?
