GPS global system of development and prospects Global Positioning System (GPS) is 70 years of this century, jointly developed by the U.S. armed forces a new generation of space satellite navigation and positioning system. Its main purpose is to land, sea and air to provide three major areas of real-time, weather and global navigation services, and for intelligence gathering, surveillance and emergency communications, and other nuclear explosion of some military purpose, the United States an important component to dominate the global strategy. garmin gps After 20 years of experiments, a cost of 30 billion U.S. dollars, to March 1994, the global coverage of up to 98% of the 24 GPS satellite constellation has been laid to complete.

GPS systems can provide users with continuous real-time three-dimensional location information to determine the user's movement speed, and provide accurate timing service, the positioning error is less than 10 meters, timing error of less than 0.1 seconds, timing accuracy than 0.000001 seconds, and its radio signal also has a certain anti-interference ability. If I have the combat units of the gps system the location information transmitted by radio communication to the operational command center constantly, plus I reconnaissance by means of the acquisition of enemy targets in the location information, and then centralized in large screen displays to show District commanders can make me able to keep up on the two sides of the battlefield, the dynamic situation, and thus its operational command provides the basis for an accurate and important. Thus, military strategists since thousands of years, "Operations Research or defeat, decisive in the distant" dream is finally a reality is not it?
As the gps navigator possess all-weather, precision and automatic measurement of the characteristics, as advanced productivity measurement tools and new, has been integrated into the national economic construction, national defense and social development in various areas of applications. With the Cold War and the global economy booming, the U.S. government announced that from 2000 to 2006 period, from threats to ensure the U.S. National Anquan premise, the abolition of SA policies, GPS civilian signal accuracy improvement in the global context, using C / A codes from the point positioning accuracy of 100 meters up to 20 meters, which will further promote the application of GPS technology to improve productivity, operational efficiency, scientific level and quality of life, stimulate the growth of GPS market. Experts predict that in the United States, just a car gps navigation system, 2000 years later, the market will reach 3 billion U.S. dollars, while in China, the car navigation market will reach 5 billion yuan. Visible, GPS technology market prospect is very impressive.
