Transmission de données par laser depuis le segment russe de l'ISS

10.05.2012 / 9:38 2 October 2012 from the Russian segment of the International Space Station for the first time on the laser channel was transmitted broadband data to the ground station

Within the space experiment (SLS) to test the equipment and demonstration of Russian technology to create space laser communication systems, conducted JSC "SPC" CPR "together with" RSC "Energia", carried out a transfer of information from the communication terminal onboard the ISS RS for ground-based laser terminal station optical observations "Arkhyz" in the North Caucasus (subsidiary of JSC "SPC" CPR ").
Information was given a total of 2.8 GB at 125 Mbit / s.
The move paves the way for a broad introduction to Russian space technology laser lines, which at lower weight and size parameters of onboard equipment can potentially provide an extremely high rate of information flow (up to tens of gigabits per second), the press service of Roskosmos.

The handing over of the laser channel real scientific information
01/29/2013 ::

January 25, 2013 the world's first space application was handed over to the laser channel real scientific information developed by Russian cosmonauts aboard the International Space Station. Information transmitted through the Earth's atmosphere in duplex mode at 125 Mbit / s on the airborne laser terminal and 3 Mbit / s from ground-based laser terminal. The structure of the data archive business information, prepared the ISS, included pictures of Earth from space and telemetry. Archive data of 400 MB transferred completely and without errors.

This is part of the space experiment "laser communication system" for the transmission of information on a laser link between the ISS and Station optical observations "Arkhyz" in the North Caucasus Research and Production Corporation "Precision Instrument Systems." Laser communication equipment created JSC "SPC" CPR "together with RSC" Energy "under the direction of Roscosmos.

These results allow us to go to the stage of practical use of high-speed communication systems in order to improve remote sensing satellites.

Open Joint Stock Company "Scientific and Production Corporation" Precision Instrument Systems "was established October 16, 2009 by converting the Federal State Unitary Enterprise" Research Institute of Precision Instrument. "

For your information:

Open Joint Stock Company "Scientific and Production Corporation" Precision Instrument Systems "(JSC" SPC "CPR") is developing:

• laser and electronic systems ephemeris-time and metrological provision of space navigation and geodetic systems;

• optical systems, including ultraviolet, visible and infrared wavelengths for space (airborne and ground), Polygon (specific and combined arms), shipborne and airborne measurement and communication systems, using several key technologies based on the use of laser transmitters, receivers and transmission of optical systems, laser retroreflectors, photodetectors, and high-precision (precision) guidance systems.

Mais est-ce que la Russie est la seule nation à envisager ce moyen de transmission de données par laser?
