The United States Have GPS We Have Big Dipper
Core tip: today, the Chinese people finally can proudly say: the United StatesGPS, we have a big dipper! "The relevant domestic enterprises have started toengage in the development and application of terminal Beidou and GPS compatible terminal R & D, also means that the use of GPS terminal users can use compass alone, terminal can also use the compass and GPS compatible.
Today, the Chinese people finally can proudly say: the United States GPS, we have a big dipper! "The relevant domestic enterprises have started to engage inthe development and application of terminal Beidou and GPS compatible terminal R & D, also means that the use of GPS terminal users can use compassalone, terminal can also use the compass and GPS compatible." Beidou satellitenavigation system spokesman, director of the China satellite navigation system management office Ran Chengqi said: "a very formal commitment, Beidou satellite navigation system provides to the world of the services are free of charge."
"The message and navigation with China, is a unique invention of Beidou satellite navigation system"
At present, the world total of four major global satellite navigation system: GPSsystem of the United States, the Russian GLONASS, Galileo System in Europe,China Beidou system.
Jean Chengqi evaluation says, the GPS system is a global satellite navigationsystem in the world the earliest established, precision maturity, service system,are in the leading level. Russia is stepping up efforts to resume constructionGLONASS system, has been basically completed, will provide the corresponding services. Galileo system is under construction, there is no formal service.
"The construction of Beidou satellite navigation system and the other threesatellite systems are not completely the same, short message service is the Beidou satellite navigation experimental system characteristics, is our advantage." Ran Chengqi said: "generally speaking, other satellite navigation system just tell you what time, in any place, while the Beidou satellite navigation system in addition to let you know what time, in any place, can also be a position information sending you out, make you want to tell others that you know the situation. The SMS and navigation with China, is a unique invention of Beidou satellite navigation system."
Ran Chengqi said: "to enjoy the service performance, and like other satellite navigation system not only free, short message communication service and special, and I want to give the vast numbers of users and enterprises to providea better application prospect."
"Before 2020 to develop and launch more than 30 navigation satellites"
Ran Chengqi said, the system test and test and evaluation show that, the Beidou satellite navigation system has the accuracy of 25 meters of the service location.By the end of next year, and then provide a formal operation service systembasically completed, at that time service precision can achieve 10 meters.
This is just the Beidou satellite navigation system of "three steps to walk" thestrategic development plan of the second step -- step third, around 2020, the Beidou satellite navigation system with global coverage capability.
In order to achieve this goal, "Beidou satellite navigation system in 2020 todevelop and launch more than 30 navigation satellites." China Aerospace Science and Technology Corporation's minister Zhao Xiaojin said: "China's space is in the high density during launch, this year China Aerospace hascompleted 19 space launch, launch 21 aircraft, including 3 Beidou navigation satellite."
Zhao Xiaojin said: "we prepare a batch of production 100 rocket, this also includes other spacecraft launch rocket. We are more than 30 satellites in 3 - 4batch production, carry out multiple, parallel test and test work of arrow."
"Promoting application of Beidou satellite navigation experimental system in various aspects of national economy"
"A few days ago, solve the 'two guest a dangerous' -- that we are very concerned about the passenger train, travel car, long-distance transport of dangerous goods vehicles in the transport process of supervision and service problems, can effectively improve the efficiency of supervision, to reduce traffic accidents, improve the safety for."
The weather bureau, Ministry of agriculture, bureau of forestry...... The relevant units and departments are organized to carry out the air, sea and spacemonitoring applications based on the run, promote our national space weathermonitoring and warning capability, reduce the hazard degree have played agreat role.
Satellite navigation system is an important national spatial information infrastructure construction, China stand on one's own satellite navigation system,has an important significance to promote national economic and social development. Ran Chengqi said: "last week I went to Guangdong to do research,to see a very welcome change: the development of the PRD many private enterprises, electronic enterprise long engaged in the terminal, I have seen theBeidou terminal application to road test and run test on the road, performance is very stable."
