What happens to a MEMS gyro's null point if it starts up while actively rotating? Does the internal hardware make any assumption about the initial motion of the sensor when it starts up?
Say the gyro is sitting on a 50 deg/s spinning turntable when it
Based on the sample data provided by Loris I have written some code to produce an Allan Variance plot of the data. The program source code is ISO C++98, and should compile with any standards-compliant compiler. G++ 4.4 tested, I expect MSVC 2k8 or hi
