Abstract

In this paper is considered the problem of autonomous navigation of the global navigation satellite system using intersatellite measurements (ISMs) on a moving time interval. The accuracy of the ephemerides of GPS navigation spacecraft in the conditions of autonavigation is investigated depending on the circumstances of ISMs. In particular, it is shown that autonomous navigation for almost two months makes it possible to provide consumers with GPS ephemerides of the submeter accuracy level (SIS URE).
