Аннотация:At present, the Radioastron (RA) Earth satellite has a very elliptic orbit,
which is used to probe the gravitational red shift effect. The objective of this
test is to enhance the accuracy of the measurement that will be used to check the
correspondence value of the effect to Einstein’s theory at one order of value better then was done in the GP-A experiment. There are two H-masers at our disposal: one onboard the satellite and the other is based at the Land Tracking Station (LTS). It is possible to compare the satellite's mutual time rate using communication radio links between RA and LTS. In contrast to the GP-A experiment, it is possible to measure the repetition and accumulation of data in the process of RA orbital circulation. In principle, this might result in an increase of the integral accuracy. In this paper, we investigate the achievable accuracy in the red shift extraction method when associated with the technical specifications of the RA mission.
