Compression of satellite data. (English) Zbl 1063.68584

Summary: We present the simple and double compression algorithms with an error control for compressing satellite data corresponding to several revolutions. The compressions are performed by means of approximations in the norm \(L_\infty\) by finite series of Chebyshev polynomials, with their known properties of fast evaluation, uniform distribution of the error, and validity over large intervals of time. By using the error control here introduced, the number of terms of the series is given automatically for a predetermined tolerance. As illustration, we apply the method to the orbits of SPOT, TOPEX/POSEIDON and SKYBRIDGE satellites.
