FIELD: space geodesy.

SUBSTANCE: invention relates to space geodesy, in particular to methods for constructing a spatial astronomical geodetic network (SAGN) on the surface of the Moon using mobile long-baseline radio interferometry systems for observing quasars. The principle of the claimed method for constructing a local (regional) SAGN on the surface of the Moon using a mobile radio interferometric system for observing quasars is that the system provides for the location of two radio telescopes (RT): on the surface of the Earth and in the Earth-Moon system, equipped with highly stable standards time. With the help of local oscillators, the received high-precision radiation from a radio source (quasar) arrives with some time delay, and, thus, two fundamental measured quantities are found: the time delay due to the difference in distances to the phase centers of the RT on Earth and the RT of the Earth-Moon system, which will change due to a change in the angle between the base and the direction to the quasar; time delay in the rotation of the Earth, the Moon. It is these quantities that are the basis of the considered method for solving the problem of constructing SAGN, clarifying the coordinates of quasars with a root-mean-square error of 0.001"-0.0001".

EFFECT: development of a new technique and algorithm for creating a spatial PAGS on the surface of the Moon.
