Much, research and development of Russian space stations for satellite prolong life

Solar photovoltaic (pv) net news: & other; Russian scientists are implementing & lsquo; Space stations & rsquo; Project & throughout; , Russia the izvestia reported that, according to the project plan, Russia consider creating a satellite in space, with a laser for spacecraft in orbit, and use the conversion of solar energy, collect and reflected light of the earth's surface to obtain electric power. In fact, as early as in 2017 the Russian state aerospace company initiated by laser to recharge of on-orbit satellite & other; Orbital plant & throughout; Study plan. At present, the main technical barriers are low photoelectric conversion efficiency and high power transmission losses, photovoltaic sunshine shed support satellite of power only output power from 10% to 20%. And this kind of small satellites have generally for 5 years to 7 years. By charging, laser can provide satellite last 100 - watt extra electric power. Russia's domestic some scientists believe that & other; Space stations throughout the &; Is a very promising project, but also need to verify the transmission way of present economic effect. This paper not only includes editor Wolfgang & middot; Dr Parr, herself, in its new energy career of more than 50 years, the deep understanding of the development of photovoltaic (pv) and system summary, also include the global photovoltaic industry professionals engaged in new energy or a review of the photovoltaic difficult development, solar photovoltaic (pv) network statement: this information is reproduced from the power grid cooperation media or other Internet website, solar photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. , the researchers said the project's vision is to supply the shaded area is located in orbit satellites with electricity, these satellites are usually because of not getting enough sunlight and power is insufficient, can't accomplish the task. In addition, besides can prolong the service life of the satellite, the project can also change the satellite design idea in the future. The article content is for reference only. Household solar street light, however, there are still some Russian experts think, & other; Space stations throughout the &; Technology application prospect is not clear, mainly depends on the technology is too complicated to implement, and USES puzzling. Russian academy of sciences, ORR khodorkovsky about ning said, & other; Space stations throughout the &; Is feasible in theory, the problem is that the implementation of the project may be in other countries, such as France, the United States or Japan as a security threat. New energy wind power in Russia, experts say, after the system put into use, will make the life extension 1 orbiting satellite. Five times, and save money. Some scientists say, according to the current assessment, will be 1 kg payloads into orbit need to spend about $50000 of funds, to build 1 kilogram satellite fees. According to the ideas of developers, the future will be in orbit to deploy a satellite group composed of dozens of charging robot, the robot charging shaped like an alien flying saucer, internal with solar panels and photovoltaic modules. Pv module used for transmission and receiving of a laser beam, it contains the control system, household and pulse battery charger, solar street lamp can immediately saving electric energy and output quickly. Using the infrared laser and efficient photovoltaic module based on gallium arsenide, energy transfer efficiency increased to more than 70%. If a small spacecraft in 100 to 500 kg, the weight of it into space costs up to $25 million. And mutual transformation between power and laser energy loss is too big, make the technology lack of economic rationality.

'photovoltaic (pv) of the world' this is a comprehensive system to introduce photovoltaic summary of past, present and future of the development of corpus, wide-ranging, and can meet the needs of different readers. “ Space stations throughout the &; Project by the Russian mo he military academy to space propulsion, designed to ensure that the small orbiting spacecraft, satellites - Repeater and Internet communications equipment running smoothly, these devices belonging to global search and rescue system. If can charge, can greatly prolong the on-orbit effective work time, save money. In addition, & other; Orbital plant & throughout; In the event of accident, will cause the space nuclear pollution. If has built charging stations for satellite in orbit, the satellite's solar panels can be narrowed, lightweight satellite, solar engineering design plan carry other equipment to make room for it. To eliminate the worry of other countries, therefore, can be considered in the international cooperation within the framework of implementation of the project, as in the case of construction of the international space station. Last year, Russia & other; Energy & throughout; 1 rocket space company successful test distance. 5 km of laser transmission technology!
