Research of the issues of frequency and time support of the GLONASS system

Abstract

The article deals with the ways of improving the accuracy of comparison of time scales of frequency and time standards in differential mode as well as the methods and algorithms for the implementation of differential comparisons of time scales of the spatially spaced highly stable o'clock. The accuracy of the location depends on many factors. With the GLONASS fully deployed orbital structure, one of the main factors determining the accuracy of obtaining the consumer coordinates is the accuracy of the navigation information transmitted as part of the navigation frame. The navigation information accuracy is determined by the state of ephemeris-time support.
