Development of the draft of navigation satellite on geostationary orbit

Requirments to the spacecraft, as an integral part of the GLONASS system was substantiated. The analysis of the possibility of using borrowed onboard systems with basic satellite "Glonass-K" was done and the extent of their modifications using the similarity by minimization of rework parts of spacecraft and its basic design-layout scheme was assessed. Design shape GLONASS was defined, the calculations of the budget of the masses, dimensions, moment-centering characteristics was done.
