Abstract:	The objective of this paper is to analyze possibilities that create complete GLONASS and GPS constellations in terms of simultaneous reception of several navigation signals in the geostationary Earth orbit (GEO). In the paper an empirical analysis is done on how many GLONASS and GPS signals can be tracked simultaneously. The result of the analysis is that up to 2 GLONASS and up to 3 GPS satellites can be tracked at the same time. These results are proved with simulation. Also simulation has shown that combined application of GLONASS and GPS significantly improves overall signal availability. Compared with GPS alone combined usage of GLONASS and GPS increases signal availability by a factor of 2 through 4. The simulation results are presented in graphs depicting probability of simultaneous signal tracking from several NSV, and in tables demonstrating average and maximum duration of observability intervals.
