GPS technology in the construction of the airport

3, topographic mapping in the planning of the airport construction, survey, design, construction and management stages requires a lot of precise topographic maps in various proportions, for the construction of the airport reclamation, but also complex underwater terrain mapping work, the use of GPS technology with the depth sounder simultaneously and plane location data collection, and then the computer and plotter plane can easily generate underwater topographic maps, drawing the underwater section of the final map can be accurately calculated quantities.

4, construction (structures) as a large-scale deformation monitoring airport terminal buildings of steel structure, due to its load, ground subsidence, temperature, wind deformation caused by the action of vibration, to ensure the safety of normal use, to be its settlement, displacement, tilt, deformation such as cracks and deflection monitoring of the project, using real-time phase differential GPS (RTK) technology to provide a continuous curve of the dynamic automation, to keep the difference between the deformation of the building in order to take appropriate preventive measures.

5, the underground pipeline network of underground pipes to draw various airport data collection can also be determined using GPS technology three-dimensional coordinates of feature points, and use Auto CAD computer-aided mapping system powerful mapping and hierarchical management and other functions, will get the pipeline data by editing, connection and filling characteristics of that form filed with the call for computer graphics files, in order to establish the airport pipeline network database.
