GPS technology in the construction of the airport

21st century, with GPS technology, continuous research and improvement will enter a new stage of development. GPS receivers more portable, flexible and easy to carry; receiver antenna, controller, batteries together, highly integrated, multi-functional, integrated; GPS to reduce power consumption, memory capacity increases, increase mean time between failures; increased observation satellite positioning system, an increase of in-band interference suppression system that allows better performance GPS anti-jamming; increasing the accuracy of handheld GPS, prices are also cheaper. Therefore, GPS technology in airport construction in a wider range of applications, in particular, the spontaneous development of the three "Compass" navigation satellite has on October 31, 2000, December 21 and May 25, 2003 The successful launch, formed a complete satellite navigation and positioning system to ensure all-weather, day to provide satellite navigation information. Combined with GPS technology and remote sensing, geographic information systems integration, will greatly enhance airport planning and design, construction stakeout, operations management, dynamic monitoring, effectiveness evaluation of the level of automation.
