METHOD FOR ELABORATION OF LASER SPACE COMMUNICATION TECHNOLOGY AND TEST BENCH FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC H04B10/118 

FIELD: laser space communication technology.

SUBSTANCE: invention is intended to confirm the technical characteristics of a space communication terminal on a test bench. The first and second communication terminals are placed in front of the first and second optical systems, the rear focuses of both systems are combined: the orientation of the optical axes of the systems and building axes of the terminals in a given coordinate system are determined; the power density of the laser radiation corresponding to the simulated distance between the terminals in space environment is provided at the input aperture of the terminals; one beam of laser radiation is generated by the first and second terminals, they are directed to the apertures of the respective systems, the passage of beam radiation through the hole located in the area of the common focus of the systems is ensured, one quasi-homocentric beam of radiation from each terminal on the hole from beam radiation is formed; the radiation of quasi-homocentric beams that have passed through the optical systems is continuously recorded by the receiving systems of the terminals; other terminal, the passage of the terminal beams axis through the centre of the hole is ensured by the rotary mechanism and the precise tracking circuit of the terminal, the control signals to which are generated taking into account the signals from the receiving system of the terminal when the radiation of a quasi-homocentric beam of another terminal is detected.

EFFECT: technical result consists in providing the possibility to simulate both the influencing factors of outer space and all modes of operation of communication terminals in ground environment on a test bench.
