Аннотация:The problem was solved of studying the feasibility and accuracy of determining the parameters of the orbits of Phobos, Mars, and the Earth by the method of modeling measurements of the radio signals from an autonomous station on the surface of Phobos. Conclusions are drawn about the dependence of the errors in determining the parameters sought on the length of the measurement interval, shift of the times of transit of the Earth, and on the makeup of the measurements.
