According to the assessment of the Western space technology experts

The Beidou satellite navigation system is of course also have their own military purposes. To be sure, the Beidou satellite navigation system has been the target of the People's Liberation Army tracking 100-1000 present, the "Big Dipper" the only countries in the Asia-Pacific region to provide regional services, but has covered the first chain of islands throughout the Pacific and South China Sea. "Compass" system to complete the deployment of 35 satellites, then the PLA will be able to rid itself of dependence on the U.S. Global Positioning System (GPS) and Russian GLONASS satellite navigation system.

    Chinese armed forces are currently using a precision lower the GPS and GLONASS navigation system, the civilian version made Beidou satellite navigation system for the Chinese missiles, precision-guided weapons and other weapons precise positioning and navigation . Beidou satellite navigation system to provide tracking and imaging, the People's Liberation Army launched a "surgical" missile attacks and the use of precision-guided munitions has been greatly improved. According to the British Jane's Defence Weekly said: the accuracy of the Beidou satellite navigation system may be a few meters within the scope of the system can also record the speed, range of error at 0.2 meters per second, synchronized time accurate to 0.02 million of a second. Important in the use of military navigation and positioning accuracy of third-generation GPS system put into use, the People's Liberation Army in the enjoyment of high accuracy may exceed the U.S. military, and the current third-generation GPS is still in prototype stage.

    Why is the Beidou satellite system so important  Accurate understanding of what location on Earth, is one of the powerful technology to any country wants to master. Beidou satellite navigation system means that the People's Liberation Army attacks in the conditions of no interference in the United States deployed its own troops, and to anywhere in the world. Currently, the U.S. can close its own global positioning system (GPS) in a specific area, so that all countries in the region can not use the system. However, after the Beidou satellite positioning system in operation, the United States, this tactic will lose effectiveness.

    In the past decade, China has launched more than 30 reconnaissance satellites, Western space technology expert assessment, the People's Liberation Army to monitor the Earth's surface area is expanding, and the increasing frequency. This is the People's Liberation Army commander can detect and track a wide range of potential military targets. Real-time satellite images and data can also be used for the coordinated deployment of Chinese naval vessels, missiles and aircraft away from the mainland. The U.S. Central Intelligence Agency was informed that, China has launched an advanced satellite, the satellite is equipped with a powerful synthetic aperture radar can penetrate mercedes benz dvd player clouds in the coverage of larger areas to obtain very high accuracy of the information and intelligence. In addition, China is currently deploying the satellite can monitor the launch of the electronic signals, which is the so-called electronic intelligence and electronic intelligence platform.

    To this end, high-ranking officers of the U.S. Defense Intelligence Agency, Ronald Burgess, space facilities, China has to do the preparation of space warfare.
