... 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. ...

THE 1999 PROJECT . The 1999 Martian Mission project is a further development of the 1988 project. It uses the results of design, research and testing activities that took place at RSC Energia since 1988. As compared with the previous project, changes were introduced into solar array panels which became modular, into lander shape where lifting body was replaced with a "discus", and into the number of the landers, with two landers - a manned lander and a logistics lander - instead of one. ...
