Аннотация
At present, the Radioastron (RA) Earth’s satellite has a very elliptic orbit, which is used to probe the gravitational redshift 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 EinsteinБ’s theory by an order of magnitude better than was done in the GP-A experiment (Vessot et al., 1980). There are two H-masers at our disposal: one on board the satellite and the other at the Land Tracking Station (LTS). It is possible to compare the satellite’s mutual time rates 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 in the integral accuracy. In this paper, we investigate the achievable accuracy in the redshift extractionmethod associated with technical specifications of the RA mission.
