If I feed accelerometer data in m/s^2 unit and dt in seconds, what is the unit of flicker and walk?
Same question for gyroscope data with unit in deg/s.
Hi Nikolay!
I have found that your Allan-Variance algorithm returns quite different output than another python implementation.
So with a close look into the code, I have found that if the line:
X = np.cumsum(x, axis=0)
where x is the input array,
is replaced with
X = x
, i.e. not cumulative sum,
then I receive equivalent results.
I think I do not completely understand the reasoning for the cumsum in the context of e.g. sensor readings and to analyse the stability of e.g. power in the power socket.
Could you please clarify -- I will be very grateful?
Best,
Ivan
