GPS is along with the rapid development of modern science and technology and set up a new generation of precision satellite navigation and positioning system has higher precision and observation time is short， the observatory without the sight， between global unity can provide the geocentric coordinate C This paper Outlines the development of GPS positioning system， this paper introduces the GPS positioning system composition， working principle of the world have some important satellite positioning system， and mainly illustrates a GPS in the car navigation and traffic management and the application of the military applications， as well as in medical applications
Along with Modern Communication Technology's fast development and GPS guidance localization technology's better and better， the GPS technology's application scope is also getting more and more The GPS localization technology in the survey domain's application， has brought the revolutionary change for the entire survey In the 1990s presented the carrier phase difference technology， calls RTK (Real Time Kinematic) the real-time dynamic localization GPS - RTK has the pointing accuracy high， not to need the intervisibility， the measuring time short and so on In recent years， more and more advanced instrumentation equipment applied in the survey domain， specially GPS being published， enormously promoted the survey enterprise's And GPS real-time dynamic measurement (RTK) localization technology outstandingly， it may， in does not build all levels of control points in the situation， only rests on the certain amount the reference point， then may the high accuracy and gives the ground point fast， the object point coordinate， moreover can real-time provide the centimeter level precision the localization the RTK technology is high by its measuring accuracy， the speed quick and so on superiority in the fast static measurement， in the dynamic measurement and the dynamic measurement have obtained the widespread This article introduced measures a digital topographic diagram concrete operations implementation using RTK real-time dynamic GPS， and obtains the data and the known entire station meter digit chart carries on the And obtains some RTK technology in the application fit and unfit In reality obtains the plain area RTK technology to have the very obvious superiority in the application， but in has mask local RTK feasible very bad
GPS is built up with the rapid development of modern science and technology of new generation of satellite navigation and positioning systems， with high positioning accuracy， observation time was short， without intervisibility between observatories and to provide features such as global geocentric This article outlines the development of GPS positioning system， GPS positioning system of composition was introduced， several important works have been the world's satellite positioning system， with an emphasis on illustrates the application of GPS in car navigation and traffic management， military applications， and applications in Tags: GPS positioning systems， GPS receiver， and GPS location; car navigation(真累，我可没用机械翻译，20悬赏我都嫌少)
