U.S. new generation of Global Positioning System Block III has been in the assembly of the commissioning phase, scheduled for launch in 2014, its use than the current GPS system with a more powerful, more reliable and more the function.
in the United States south of the central city of Denver, a huge Lockheed Martin plant, the workers are stepping up assembly of more than 30 stars Block III satellites. These satellites will be replaced in 2014 is currently orbiting GPS satellites, providing a powerful dual-use services, other countries, civil satellite positioning system to share its services. According to reports, the system will be 70-90 satellites, to provide navigation and positioning services to the existing GPS system only 30 satellites. Therefore, Block III will greatly enhance the function of location-based services will be positioning accuracy from 10 feet (Editor’s Note: 1 foot=0.3048 meters) raised to three feet, and can provide indoor location-based services.
In addition, Block III will add two civilian signals, one of which is to signal that require high-precision positioning activities such as exploration, etc., to provide more accurate positioning services. Signal transmission in the military, the military departments by decoding technology has not only received military satellite and an international satellite signals, and signal transmission can share the civil service, greatly enhance its inter-city skyscrapers and the dense jungles of signal transmission and the ability to locate .
