Abstract:

Since the moment of creation of the RT-70 radio telescopes in Evpatoria (1979) and Ussuriisk (1985) they have been used not only for control of deep-space vehicles but also with the purpose of conducting a wide range of radio astronomy explorations.

Both radio telescopes within the international very-long-baseline interferometry (VLBI) networks (the USA network Deep Space Network (DSN), European and global VLBI networks, and Australian network Long Baseline Array (LBA)) regularly participated in the observation of compact space radio sources by the VLBI method.

The Evpatoria radio telescope RT-70 was involved in performing radar-aided explorations of the Solar System bodies. Since 1999 within the framework of Russia-Ukraine collaboration a new radio-astronomical method of VLBI location for exploration of the Earth group of planets, the Earth approaching asteroids and space debris has been under development. Observatories in China, Japan, Poland, Italy and the UK participated in these experiments. Since 1998 the Evpatoria RT-70 has been operated within the international 'low frequency VLBI network'.

For the future the radio telescope RT-70 is expected to be used in the international project 'Radioastron' for joint observations with the space-based 10 m radio telescope.
