Accuracy Limit of Cosmic Signal Simultaneous Registration

The problem of determining the dependence of fundamental accuracy of coordinate time support of satellite positioning systems on the synchronization process, is considered in the paper. Using the Moller-transformation of coordinates and time, the process of space signal registration by artificial Earth satellite, as well as by the ground-based observer in an inertial reference frame where the relic cosmic radiation is isotropic, is simulated. It is shown that the estimated accuracies of the coordinates definition of cosmic events in the earth observer’s chosen inertial and quasi-inertial reference frames, differ.
