RadioAstron satellite control (command transmission, telemetry, orbit measurements) will be conducted from Evpatoria and Bear Lake control stations. ... Coarse orbit measurements will be carried out from control stations. Each measurement takes ten minutes. ... Orbit measurements at tracking stations give only radial component of spacecraft velocity but the measurements are going continuously during observing sessions. ...

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...
