The paper presents a some specific method of the gravitational frequency shift measurement for communication radio signals between the spacecraft and ground tracking stations. It is based on the maximum likelihood algorithm and utilizes the Cramer-Rao bound to estimate the accuracy of signal parameter determination. It is carried out with the bank of data obtained during the "Radioastron" mission. Attention is concentrated at a compensation of the relativistic Doppler effect and frequency noises of the standards used in the experiment.
