Hello, EEVBlog peoples !
Always Thanks you for your help.
in this moment, i should calculate the Allan Variance from logging data of INS to estimate error.
i recorded Gyroscope and Accelerometer, Temperature datas for 97 minute without any movement.
and now i following Matlab reference to obtain Tau-sigma graph.
(
https://kr.mathworks.com/help/fusion/examples/inertial-sensor-noise-analysis-using-allan-variance.html )
Sampling time is 97.1061 minute. (from 91.98 sec till 5918.346 sec)
Total number(length) of data is 836185.
but, i can't understand what is a
Fs.
Anyone know about it ?
i attached screenshot of page.
(That page support Example for that. but, unfortunately, my student version Matlab 2017b has not that example... )
Please, let me know !
