    This paper summarizes and presents S.P. Korolev Rocket and Space Corporation «Energia»
    experience concerning space wireless power transmission (WPT) system project and describes way
    to investigate the effect of atmospheric phenomena on long vertical link from ISS to Earth surface.
    WPT systems could be used for remote power supplying of the different consumers. First of
    all, there are autonomous technology modules for microgravity experiments, due to small and fixed
    receivers, micro- and nanosatellites, equipment for explorations on the Solar system body’s surfaces
    during science planet missions, space transport vehicles with electric rocket propulsion systems.
    RSC “Energia” develops ISS based WPT system and plans beginning of technology
    realization in the space experiment. The main components of proposed system are: fiber-coupled
    irradiation source based on semiconductor IR laser diodes or fiber laser with power of 50-1000 W
    in CW regime and power conversion efficiency above 30\%; optics for creation ~10 cm diameter
    beam in 1km distance with transmission near 95\%; special GaAs/Ge and some other material
    omnidirectional photovoltaic receiver with dimensions of 20 cm for conversion of monochromatic
    IR irradiation with high energy density to electric energy with efficiency near 50\%; fine guidance
    system for tracking objects with angular rates less than 3 deg/sec, based on laser tracker, retroreflectors
    on receiver, and dual pointing by motion platform and controlled steering mirror (overall accuracy
    near 5 mkrad). Part of chosen equipment was tested in experiments we provided recently. Real
    WPT system at a ranges of 100-1200 m in atmosphere with transmitted power levels of 40 W was
    Main components of necessary WPT equipment – optoelectronic system for narrow beam
    creation and guidance system – can be used in atmospheric researches. Advances in laser
    technology are opening up new views of the Earth's atmosphere and placing the laser at the
    forefront of land research tools. Using laser space systems opens up even more opportunities.
    Special tunable laser or simple laser source with optics placed on space craft can produce narrow
    beam and point it to Earth surface. Irradiation received on surface will provide quite new
    information according to atmospheric characteristics (wind velocities, transmittance, turbulence
    characteristics and etc.).
