Xinhua Beijing on March 1 (Xinhua correspondent any Qinqin Rosa) – China will set up in 2020 global navigation system. CPPCC, China’s space technology experts Qi Faren 1 to accept Xinhua News Agency reporter an exclusive interview that a satellite navigation and positioning of national economic construction, national defense is essential. With the spread of the trend of globalization, communication and navigation for the production of construction and homeland security role has become increasingly evident.
navigation satellite, there are two, one is regional, and one is global in China is the Compass and Compass II. Qi Faren to Xinhua News Agency reporter 介绍 了 China into the global navigation system complete “three-step” program.
first step is a regional navigation system, satellite positioning systems has been completed Compass, which is China’s independent research and development, the use of geostationary satellites to provide users around the clock, covering China and the surrounding areas of satellite positioning system. China has in the October 31, 2000, December 21, 2000 and May 25, 2003 launch of three “Compass” navigation satellite test geostationary orbit to form the “Dipper” regional satellite navigation system.
Beidou satellite after the earthquake in Wenchuan played an important role. Qi Faren, said in a communication interruption after the earthquake, the Compass system receiver to carry the rescue force arrived in the disaster area by the specified time, as the initial period after the earthquake disaster and the only way to contact the outside world.
“but the navigation has been unable to meet regional demand for real. Is to grow, China needs to build a global positioning navigation system to adapt to scientific developments.” Qi Faren, said Compass II GPS came into being, by the second and third steps together.
the second step, the “five-second” pre-completion launch 12-14 satellites missions, composed of regional, can be autonomous navigation positioning system; third step, that is, in 2020, There are more than 30 satellites worldwide.
Compass II satellite navigation system will overcome the shortcomings Compass system to address the problem of limited coverage area, and will have a variety of other applications such as rapid positioning, short-message communication, precision timing and so on. Qi Faren, said Compass II for soldiers and civilians in China and surrounding areas offer land, sea and air navigation services, and promote satellite positioning, navigation and timing services applications for the aerospace positioning and orbit determination provides a means to meet the navigation location information exchange needs.
he said in plain language: “Compass II made the equivalent of GPS, GPS applications as long as the United States where, Compass II can be applied.” Scientists can monitor the crust of tiny moving to to help predict earthquakes; mapping can determine the ground of the border; when the driver lost discern the direction; army can guarantee the accuracy of such forward line.
in the Chinese market, the current civil global satellite positioning system car navigation best embodied in the instrument, the U.S. GPS car navigation equipment in China accounted for the major markets. Qi Faren that made GPS Compass II that was put into use, the GPS and the United States compete for ordinary consumers, advantageously, the Chinese Compass II car navigation systems will be compatible with GPS.
“into a significant global navigation system, navigation and China it will provide a reliable guarantee timing, the world can also use this system in China.” Qi Faren told Xinhua News Agency reporter, the development of China navigation , is a manifestation of national capacity, will enhance China’s ability to use information to form a satellite application industry, the development of a strategic new industries, markets, services, real people’s lives.
Qi Faren is the Chinese Academy of Engineering, Fellow of the International Academy of Astronautics, has served as China’s manned space manned spacecraft system designer.
