About the paper

Keywords: Space vehicle, VLBI, Doppler measurements, carrier phase measurements

“Quasar” VLBI network has all the capabilities to perform high-precision ground-based radio observations of the space vehicle in deep space. Multichannel broadband recording of space vehicle and quasars signals combined with the software correlator allows configuring the system for processing the target signals in different radio bands and modes including single dish one. The potential of the “Quasar” VLBI network for ephemeris support of the space programs was confirmed by the following observations: Doppler and phase measurements of RadioAstron spacecraft and VLBI observations of Mars Express, lunar landers, GLONASS and Beidou navigation satellites. The measurements errors correspond to the theoretical values.
