Compass satellite navigation system from the road to see our core technology str
1 17 0 12 points at the Xichang Satellite Launch Center in China with a "long march on the 3rd C" carrier rocket, third satellite successfully Navigation Satellite into orbit. So far, the Chinese move to create its own global satellite navigation system "Beidou second generation" has taken a solid step in the direction. It is learned that the rest of the future China will gradually launch 30 navigation satellites, the final network plan completed in 2020, the earliest in 2015 to provide global coverage of the location, timing, speed and communication range of services, China will become Following the United States, Russia, the European Union, the fourth independently owned global satellite navigation capabilities.
From the "Big Dipper" to "Galileo"
Navigation satellite navigation system is divided into regional and global navigation. Regional navigation satellite network less, generally 3-4 navigation satellites can be. The global navigation, the general need 4-5 geostationary satellites and more than other 20 formed the non-geostationary satellite constellation network.
2000, China launched two experimental geostationary orbit, navigation satellites, in April 2003 it launched the third satellite, "static orbit" satellites, basically covering all of China's regional navigation and positioning system, the system known as "Compass" navigation system.
To the "Big Dipper" an experimental stage of development, their technical parameters is far behind the United States GPS , Also behind the EU in 2002 decided to start the "Galileo" system. But "Compass" has proved that China has the technology more mature global navigation and positioning system research and development capabilities.
In this time period, the EU launched in 2002 to compete with the U.S. GPS, "Galileo" program, in 2003, the European Union for funds and market development considerations, sent to China Cooperation Development of the invitation. China became the first non-EU participating countries.
"Galileo" is the world's first civil global satellite-based navigation and positioning system, and its positioning accuracy of 1 meter, much higher than 2003's GPS positioning capability of the United States. Figuratively, said a military expert, GPS system can only be found in the streets, "Galileo," can find the door.
2003 the end of the actual completion of the Chinese regional navigation system, "Compass" on the 1st, the EU signed the 2004 technical cooperation agreement, China pledged 230 million euros of the huge amount of money very quickly the first 70 million euros the delivered.
Encourage China to give up autonomy to create, and take the road of international cooperation, is based on psychological and physical dependence: first, the Europeans basically ignore the United States to Europe, "breaking up" the pressure, showing the relationship between China and the EU "strong" sex; Second, China has committed huge investment and considerable funds credited into account just the lack of start-up capital of Europe, but from the economic level, the long-term China to maintain high GDP growth, this material shows that the more dependent increasingly strong trend; Third, China and the EU in the international political arena, support each other, against American unilateralism, China-EU relations to a higher level of partnership development; last, cherished by the Chinese side to promote technological progress in international cooperation inner urge, and Europe harbor in the massive Chinese market to commercial opportunities of the inner urge both sides to meet one another, is "cooperation" of the fundamental characteristics. Cooperation is annoyed embarrassment
Into 2005, the European political begun to shift, before the "pro-China" German Chancellor Gerhard Schroeder has been a step back from the right-wing political parties, pro-American politician as the new Prime Minister Angela Merkel, leader of France also entered alternate times, decreasing the influence of Jacques Chirac, the French pro-American forces began to rise. Pro-American political figures have come to power, the EU is committed to a "multipolar world" dim desire, Europe, and quickly move closer to the United States. China began to crowd out the European Union. In this political atmosphere, the Europeans began to equal the Chinese partner "downgrade" to the need for Europe "toe" of the "junior partner", alienated China, or China, higher material requirements.
Seeing huge amounts of money invested, but not commensurate with the treatment, even treatment is also lower than not put a dime in the other non-EU countries such as India, China greatly dissatisfied. China is not only not get into the "Galileo" project decision-making body, even in the technology development on the European Space Agency was deliberately blocked by obstacles, China has become one for the European Union who played for the "oily fish", in addition to hung a participant's "good reputation", the other a no income but have to bear a huge capital investment, such "embarrassing ending" the Chinese side was furious.
