Re: chinese satelittes
The Chinese official media Wednesday (on 7th) reports said that, China has chosen a location in Hainan Island, prepares to establish the China fourth satellite launch center in there. On the other hand, the world consensus generally believed that, China's succeeded on the other day the launch BeiDou navigation experiment satellite, symbolized America, Russia, Europe, center four strongly strove for hegemony on the satellite navigational system the pattern already to form. Hainan Province agent Governor Luo Baoming said that, the new satellite launching base will construct is leaving the Hainan provincial capital seaport about 60 kilometers RunChaung. Xinhua News Agency reports said that, RenChang the satellite launch center also will include an outer space subject scientific park, a rocket assembly plant and a control center. The new selected location has the important practical value China at present altogether has three satellite launch center, in Sichuan Xichang, in Gansu Jiuquan, but also some in Shanxi provincial capital Taiyuan. Early time some reports said that, the Hainan comparatively backward economy mainly is relies on the tourism and the agriculture, therefore, the Hainan authority to the central authorities solicit, hoped central can elect the new satellite launch center location in Hainan, thus stimulates local the economy. At present the Hainan government already decided on the visit RenChang satellite launching base the admission ticket price, a ticket price reached as high as 500 Yuan. China military expert, American gram 莱蒙 research institute Asia center researcher Lin Changsheng when accepts the interview said that, China establishes the new satellite launch site in Hainan to have the very vital significance. He said, although China passes in Sichuan, Gansu and Shanxi respectively has a satellite launch site, but these three launch sites all have several disadvantageously place. One is they all occupies on the high track, the launch satellite rocket power was inferior to the low track is strong; Two is because the Chinese present launch vehicle more does in a big way, all has no way in the inland very many bridges culvert to pass, the transportation is inconvenient; Three is 11,000 launches appears the breakdown, the inland population density is high, when rocket whereabouts can cause the local resident to be injured. Lin Changsheng believed above, can avoid the question in the Hainan establishment satellite launch site. He said that, "first, Hainan approaches the equator, the earth rotation kinetic energy quite is strong, therefore the rocket may launch with the same fuel launch satellite the satellite high, but is not good in the high track; Second is transports conveniently, it may through the sea transportation, not the bridge, the culvert influence; Third, after it launched arrived the sea sky, if has been defeated also is falls on marine, could not to the inhabitant which launched under the track pose the threat. Therefore, China has the very big benefit in the Hainan establishment rocket launching base. The "China advances into the satellite navigation four to be strong On the other hand, this February 3 0 28 minute, China launch vehicle successfully delivers in the Xichang satellite launch center with "the Long March third armor" the BeiDou navigation experiment satellite the outer space. The Xi'an satellite observation and control center transmits the data indicated that, the satellite accurately enters prearranges the track. Country's the and so on US, Russia, England, France mainstream media and the Hong Kong and Taiwan media rapidly reported the Chinese this success launch satellite news. The world consensus generally believed that, this symbolized China's BeiDou satellite navigational system greatly advanced a step to front, forms America, Russia, Europe, center four strongly strives for hegemony on the satellite navigational system the pattern. China military expert Lin Changsheng believed that, this kind four strongly strives for hegemony the pattern view to make the sense, because before this dubhe satellite launch, China has already launched four BeiDou navigation satellite, these satellites belong to the first generation, they with American, Russian and Europe's satellite compare also have the very big disparity, because they also pause in the high track and the region use stage, only can in the Asian and Pacific area navigation. Lin Changsheng pointed out that, this secondary emission BeiDou satellite in the technical stratification plane already with America's, Russia, Europe's satellite belonged to a scale. He said that, "recently launched this new BeiDou satellite was the second-generation, also was BeiDou-2. The BeiDou-2 satellites are similar to American and Russia's satellite, belongs globally, also is the low track. Then, this satellite if experiments successful, new BeiDou-2 on such form the global character like GPS to guide Chinese international pioneer 导报 to report said, looked from the present competition pattern, US develops in the world first whole world satellite navigational system GPS or occupies the dominant position without doubt, but its superiority substitutes for by Russia's standard Luo river natrium Si and European Union's Galileo as well as China's BeiDou satellite navigational system. Looked from the technology and the application prospect that, four big systems respectively have the fit and unfit quality, if GPS wins in maturely, Galileo wins fine in, then the standard Luo river natrium Si's greatest value lies in the antijamming ability to be strong, but China's BeiDou satellite navigational system superiority lies in the interaction and openness.
