中广网 Beijing on January 21 news (reporter Li Yan) January 17 morning, our success will be the third Beidou navigation satellite into orbit, this indicates that China has independently developed production of the Compass satellite navigation system construction, has taken an important step. So, the development of China’s Compass navigation satellite development will be what kind of impact. To this end, extensive interviews with military correspondent Li Yan Jin Yinan National Defense University Strategic Research Institute, Major General, on the topic for your detailed analysis.
Reporter: Some analysts believe that the satellite navigation system is an important national information infrastructure and the implementation of the strategy, reflects the country’s comprehensive national strength is an important symbol, we should be to understand how the Bible?
Jin Yinan: With this process social information (accelerating), the satellite navigation system that not only security in a country, the national commercial applications, the role has been growing. We can see, we are now GPS system is very typical, it’s positioned where you go easy, it tells you where the next intersection, turn left and the number of meters, in addition to a highway you have to Where? You just set your destination, and your starting to set, then it gives you a selection where the best location, even if you open later it tells you turn back.
we are now in the car with the GPS system we used a lot, but this system is the Americans. This system is common in the United States around the world, when we all feel very convenient. But there is a problem, do not say that we, the European system of U.S. global positioning system was not very trust, so the development of a European Galileo system to be independent, to complete the 30 Galileo global satellite navigation and positioning distribution.
self-developed satellite navigation systems can not be controlled by others
Reporter: We know that Europe is a traditional ally of the United States are NATO members. Well, since this way, why should Europe invest significant resources to develop the Galileo system? It is not there some of this lesson?
Jin Yinan: Europeans learned more. Such as the 1999 Kosovo war, Europeans found that although the same is NATO, the European aircraft can not mount the U.S. precision-guided weapons. United States has developed rapidly, to go very front, even if the European NATO member states a little behind the development of some of the United States of Europe on the system unacceptable. In fact a large number of precision-guided weapons, the U.S. GPS guidance, no such system in Europe.
This system is also used in Europe, with what is it? United States only to the European commercial applications. Such as the GPS system it developed business applications, business applications, it gives you the highest accuracy is ten meters, that is an object on the ground ten meters in the air, it’s business image as a pixel resolution ten meters, but not very high of. This definition is very general, like the development of the Galileo system in Europe now, it’s positioning system open commercial sale, commercial positioning system of its accuracy is one meter is one meter pixel image is a point that it precision than a tenfold increase in the GPS.
we can see is definitely not the United States with a meter, is definitely not ten meters, the Americans used the GPS system, especially the use of U.S. military security, which are about one meter, or even a meters 0.8 meters, 0.7 meters, 0.6 meters, 0.5 meters is possible, especially his second-generation GPS in use, can reach 0.3 meters to 0.2 meters, is 0.3 m to 0.2 m pixels on an object in a point. The same allies in Europe, the United States to ten meters.
In such circumstances, the Europeans do not develop their own system, right? Therefore, the Europeans also feel, not subject to the Americans, it wants its own system.
satellite navigation system in the future national security will play an increasingly important role
Reporter: As Jacques Chirac said this was emotion, If you do not own satellite positioning systems, Europe will inevitably become a vassal of the United States.
Jin Yinan: The United States had veiled criticism of the European Galileo system, why do we have a GPS system, and also commercial applications, when most of the projects are free, you can use for free, why but also to develop the Galileo system? Europeans are very clear answer, the future economic development in Europe do not want to, and convenient transportation, or even the U.S. military dropped all the application tree. If the U.S. happy, not to how do I use? Therefore, considering Europe is very clear.
Europe with NATO, the United States is a community, such a military alliance feel the need to carry out its own system, not to mention we do. Today, we use the GPS system is very convenient, very convenient, many projects are also free, then taking into account our future security, we must take into account the establishment of our own system. Must engage with the European Galileo system, Compass if we engage in our system, we are there is a big future security risks.
when it comes to national security, the core area, core data, core technology, no one will give you, no one will give you, especially the navigation system in the future whether military or civilian, whether it is the development of country’s economic or national security, the future of navigation systems have an increasing role.
to build global satellite navigation systems, international space orbital distribution into a problem
correspondent: a global positioning satellite navigation system, where the difficulty of the performance?
Jin Yinan: I think the difficulty of performance in many aspects. First of all, now it is not just a technical problem, because many countries made the satellite can send, Israel, Japan can be made, including India.
now the problem lie? Now the problem is the distribution of orbital space. In particular, GPS positioning space orbit, geosynchronous orbit now that it has allocated space is basically finished, the track assignment is now a big problem.
In addition, there is a communication frequency distribution, is positioning satellites constantly transmit signals, which share the channel, the frequency range used by the International Federation of radio, is an organization under the United Nations approve the application the right to use your channel is the frequency distribution of power. These are what we say and not so much the satellite technology itself, but for the entire system, because not a single large satellite navigation and positioning system, GPS is now 24 satellites that behind, to send 30 satellites, Galileo system is slightly more than 30 satellites, the Russian GLONASS satellite system, the relatively small number, about 20 satellites around.
such a large system, between the exact location of the satellite, its distribution in the air, make your ground, you in this country at the same time try to find three more stars, this distribution, location coupled with the frequency use rights is a very complex issue.
Correspondents include: There is now a frequency to snatch the problem?
Jin Yinan: And you do not pay close attention to your sub-optimal frequency will not work, you do not pay close attention to the words of this sub-optimal frequency, Galileo will be share out. So now where the problem occurred? We Compass II and Galileo systems, we apply the ITU frequency range, there is a band Galileo and Compass II systems overlap, the overlap who is using this frequency band? The international arbitration is it? Who is who fired first use.
is why we are stepping up launch it? We do not step up launch, do not step up distribution network, then this would destroy the band. Future re-apply for it, your equipment, firing frequency above the loop, the frequency standard punctuality, the crystal must be replaced, very troublesome.
from today, we see, in fact, an early launch Compass II system, so Compass II system put into use as early as possible, I personally think it’s important, I think than the manned space flight, landing on the moon than the Chang-e more important.
Reporters: because it relates to a country’s overall strategy?
Jin Yinan: Yes, related to national security, to the country’s economic development, from the market economy, we need to occupy the market this system, the national security needs, the Big Dipper II system is put into use to enhance the overall security of our country is a huge role.
