In the article the analytical expressions, which together make up the mathematical model of the radio signal received from the satellite radio monitoring complex relay, are presented. It provides means of measured time delays and frequency shifts of several radio relay satellites to obtain parameters of the position of ground terrestrial: the difference between the distance and the difference in radial velocity, which ultimately allow us to calculate the coordinates of ground terrestrial. Calculations of energy routes «up» and «down» contribute to the development of the requirements for determining the coordinates of the elements of the main subsystems and related relay satellites, as well as to the elements of the entire positioning system ground terrestrial. To test the adequacy of the developed model a computer simulation is implemented. In conclusion, the article indicates the directions of further research on the definition of the parameters of motion of ground terrestrial on the basis of the difference-Doppler measurements.
