Synchronization of on-board scale in spacecraft with GLONASS system time using radionavigation equipment

Currently there is a problem of spacecraft time scale synchronization. One of the main problems is trajectory parameters and satellite coordinates measurement. The satellite navigation system is a complex of orbital objects, control stations and user receivers that have space-time referencing. Moreover the most parameters of the orbital motion of the navigation space craft are expressed through time functions from consumer point of view. Usually the on-board time scale correction occurs sporadically, under its offsetting relative to the system scale more than allowable value. The spacecraft on-board time scale synchronization method on Geostationary and High Elliptical Orbits with the GLONASS time scale system based on measurements of navigation parameters using radionavigation equipment is considered. The computer simulation results for acknowledgement of synchronization algorithm feasibility are presented here. This report relates to the instrumentation and can be used to improve the determination of the time - frequency parameters of very stable oscillators (time and frequency measure) placed on mobile objects, for example, aircraft or spacecraft of the GLONASS system.
