In the long human history of the conquest of space, there is a very regrettable thing, and that is "Space Station" is lacking. When the communication satellite orbit correction when energy is depleted, its life will come to an end on a low earth orbit satellite will land, burned to ashes in a fiery embrace the atmosphere, the Earth's high orbit satellites will deviate from the calculated orbit, like like wandering aimlessly in space Piaohang become space junk. However, all this will soon change, "junk" communications satellite savior, "track patients' going to save them. 2002, London, UK "track rehabilitation," the company began to design, develop "track patients' new space spacecraft to rescue to be scrapped due to fuel exhaustion and television communications satellite. Today, two years later, the development work to get a breakthrough, a new aerospace rescue aircraft full name "cx track life-sustaining device," has also been a huge change in shape, the program is also more realistic, many structural components have been identified, transport aircraft The basic way into space has also been finalized, the design and manufacture of specific parts of the task has been assigned to subcontractors completed, plans for the first test flight in 2007.
Since the fuel consumption factor is that many of the most important reason to stop using satellites, so modern communications satellite television equipment usually comes with a very sufficient fuel resources, but it is also very limited. "Track patients' program designers, announced by helping this aerospace rescue aircraft to supplement the necessary energy, the satellite will be able to extend the service life of 10 years or longer, communications satellites and thus can increase a conventional life times.
"Track patients' rocket will be equipped with electric ion engine to ionizing xenon as the working fluid in solar energy. Its shape is like a _truncate_d cone, bottom diameter of about 2.6 meters, about one meter high and 1.1 meters in diameter at the top. As the "track patients' size and shape of the European" Allie Jana -5 "effective carrier rocket adapter is identical, so this" track patients "will be able to inter-carrier rocket and payload adapter unique form into space.
Into near-Earth orbit, the "track patients' automatically along LEO flying under the radar remote system control light, cautiously approaching the communications satellite to be rescued. Each communications satellites middle of the center of gravity, there is a lift or apogee orbit correction engine nozzle, fuel consumption because the energy is completed, the little engine has no purpose, just to be used as a "track patients' contacts and communications satellites for By special extension rods, so that the two are joined together. After that, "track patients' will provide satellite energy and prolong its service life, while correcting orbit satellite systems, and with its own engine, helping satellite re-orientation. "Track patients' can also help those satellite scrapped long, can treat just those satellites into space, because orbital calculation is not accurate, the last stage of the launch vehicle or engine acceleration device failure or other reasons can not be successfully into orbit.
"Track Rehabilitation" now forward all television communications companies to introduce their products. Braden said one of the leaders of the company, communications satellites typically cost $ 250 million, through the "track patients' repeatedly extend the life, the cost is relatively low, compared to launch a new satellite to replace much more affordable. Braden said communications satellite in space rescue service work is a huge emerging market, has a very good prospect. According to company estimates that by 2011, life expectancy of more than 80 satellites in the 1980s and 1990s launched a communications satellite to an end, they will be the company "track patients' bailout object. In addition, the company plans in the future to a group of "track patients' different heights into near-Earth orbit, ready to rescue various satellites, which can to a certain extent, the battle of communication to respond to customer needs, rather than wait Under "Allie Jana -5" of a rocket launch. |
