Recently, according to American business net the report says, world each country obtained tremendous progress in aerospace domain, among them Sino-US Russia the Three Kingdoms is highlighted particularly. After afterwards beautiful Russia, china becomes the 3rd implementation to launch manned spaceflight spacecraft the country of aerospace. The aerospace nowadays and our life be closely bound up, the satellite lives to production no matter or martial national defence is built, had indispensable effect. In the life, we are affirmatory from the essence that does not open navigation, the missile on the military affairs blasts off, the coordinate fixed position of vessel of the ship on boundless and indistinct sea is waited a moment, and the weather forecast that we produce life place to need is waited a moment, prop up from what do not open powerful satellite. So satellitic definition is higher, these information that provide for us are more accurate. So how much is the satellitic accuracy that regards domain of the aerospace on the world as the most outstanding Sino-US Russia the Three Kingdoms respectively?
According to American business net the report says, the highest accuracy of American satellite can achieve 0.3 meters, highest accuracy is the satellite of Russia about 1.5. So the China that regards the world as the 3rd big aerospace, is our satellite highest how much is accuracy? All the time since, the satellite with the widest application on the world locates the system is American GPS, because the whole world covers an area wide, definition is high, get be admissived extensively so, and be accepted by most person place. American GPS has developed error limits to won't exceed 0.3 meters nowadays, this is a very terrible accuracy, can say to depend on the missile that GPS fixed position will come to blast off, exist scarcely hit the circumstance that slant to appear. But is the GPS accuracy that you think we are used also met so tall? If you feel,be that you are too innocent. The American satellite with so high definition United States of be confined to is used, say well and truly to be confined to American for military use. And the GPS error that opens his country to use all is controlled in 10 meters.
The Russia that regards spaceflight as big country has prophetic vision early, they know the United States is done not have so meet kindly the satellite with a so high definition takes the world to share, and if blindly depend on American satellite, in case when encountering emergency, if the United States shut GPS, will cause a deathblow to Russia so. For no longer person of be enslaved to be enslaved to, be not being pulled by others nose goes, development of Russia spaceflight person gives system of GLONASS satellite location, had extended the 2nd generation nowadays, predicting meeting realized the whole world to enclothe 2022, at present the error accuracy of this satellite system is 1.5 meters about.
So does Chinese satellite locate how much systematic error is? It is current that north fights a system my countryman is used and the location system with the most advanced for military use, when intermediary evaluates Chinese north to fight outside, express, this is a global location system that replaces American GPS the most likely in future. Increase what fight satellitic measure as Chinese north ceaselessly, the whole world covers a range wider and wider also, definition is higher and higher also. Once the accuracy of system of location of Chinese traditional satellite all is in 10 meters of above, already narrowed this one error 1 meter is controlled nowadays. The expert expresses, obtain a breakthrough ceaselessly as the quanta technology of our country, if quanta satellite forms the whole world to enclothe a net, its accuracy will achieve 0.1 meters, more existing than the United States GPS is even advanced.
