GPS technology in the construction of the airport

4.5 full-featured, widely used in the precise determination of the location coordinates of observation point at the same plane, but also determined the land elevation. But also with real-time kinematic positioning mapping digital topographic maps and construction stakeout work.

4.6

High degree of automation, simple GPS receivers now have become compact and fully automated operation, the operating personnel only as required to the host, such as connecting the antenna and the antenna unit to accurately install the measuring station, connected to power to start the receiving unit. The amount taken at the end of the antenna high, turn off the power, to close the receiver installed, will complete the field data collection tasks.

5, GPS technology status

As GPS technology has significantly more features, has been widely used in geodetic surveying and mapping industry, precision engineering survey, aerial photogrammetry, crustal deformation and building monitoring, resource exploration, navigation and control of vehicles, urban mapping, etc., and have begun to use in sea and air navigation, vehicles lead the line, missile guidance, aerial remote sensing, marine, navigation, communications, meteorology, civil aviation and other fields of engineering survey, design, construction management, final acceptance, dynamic monitoring, equipment installation, time transfer, the speed measurement. In particular, the Earth used to create dynamic parameters of global and national geodetic control network, the establishment of geodetic reference land and sea, monitoring the state of modern plate tectonics to determine the instantaneous position of aerospace photography, etc., and achieved encouraging results.

Second, GPS technology in the application of airport construction

Mapping work is the first airport project and infrastructure c
