A Method for Positioning and Timing Support of Remote Users based on Mobile Radio Interferometry

Abstract

The results of a comparative analysis of methods for positioning and timing support of remote users based on GNSS measurements from a GLONASS receiver and observational data on quasar radiation from compact very long base radio interferometric (VLBI) systems are discussed. Using radio telescope measurements increases the stability of positioning-and-timing and navigation support of users owing to observations of radio-frequency radiation emitted by the sources of natural origin. The approach proposed in this paper focuses on using radio interferometry for precision positioning and timing of remote radio telescopes. This method can be helpful for specific applications relevant to positioning and timing support for remote users with an arbitrary positioning topology.
