The paper presents the analysis of the essential accuracy level expected from the modern fundamental coordinate and time data of both existing and prospective satellite navigation and telecommunication systems, while solving the real-world problems of ballistic and navigational support. The paper shows that the respective analysis of the effect of the navigational coordinate and time data uncertainty should be performed based on the estimates of the required ballistic and navigational support of the satellite systems, taking into account the differences between the theoretically attainable level and the practically feasible level of the accuracy for the fundamental coordinate and time data. The authors found out that the currently discussed requirements for the fundamental coordinate and time support complex, which involve a navigation access to a submeter accuracy, at least for the commercial systems, are overestimated not only for the current state, but also for the long term systems.
