[email protected] Abstract. Ground-based support is an essential condition for the suc- cess of almost any space astronomical project. Optical telescopes are widely used to support space-based projects. In the first part of the pa- per, the main areas of the support are briefly considered: cooperative observations – both synchronous and asynchronous, ground testing of service systems (for example, fine guidance systems), astrometric (ballis- tic) support, etc. Some examples are briefly considered. Special attention is paid to ground support for the WSO-UV (Spektr-UF) space observa- tory. Specific examples of both science and technical support (new spec- trographs designed for cooperative observations, ground testing of the guide sensor system) as well as organizational issues are discussed. The call for applications that require preliminary ground-based observation has been announced. Seven applications were selected.

A comprehensive studies electromagnetic radiation, gravitational waves, and el- ementary particles, such as neutrinos and high-energy cosmic rays emitted by the same extraterrestrial sources, in order to obtain information about processes occurring in space, is an essence of multi-channel approach. The multi-channel astronomy paradigm is becoming firmly embedded in science. For example we can refer to (presumably) first professional book on the issue (Multichannel Astronomy, Ed: A.
