Estimate of angular speed of body rotation with the help of tracking system / D. I. Bugrov, A. V. Lebedev, V. A. Chertopolokhov. //Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2014. № 1. P. 68-71 [Moscow Univ. Math. Bulletin. Vol. 69, N 1, 2014.].
The problem of determining the rotational angular velocity of a body using the records of the matrix orientation supplied by a tracking system is considered. Two methods of solving this problem are compared. One of them is based on the representation of the function in the form of a partial sum of the Fourier series and the second one is based on the Savitzky-Golay filter.
Key words: angular velosity, tracking system, partial sum of Fourier series, Savitzky-Golay filter.
