GPS technology in the construction of the airport

With our high precision, multi-resolution network of GPS to establish spatial orientation, GPS technology can greatly improve the frequency of use. Practice has proved that GPS technology can be applied to the whole process of construction of airport projects, for the play technology, increase the technology content, improve project quality, have a very important role, the current GPS technology is mainly used in the following areas:

1, the control survey network to establish the construction of the airport is a comprehensive project, it is necessary to consider at the airport to establish an independent high-precision control network, but also the countries with which the city, the local control network coordinates the necessary conversion. Plane through the GPS technology to control network and testing, such as point measurements, and GPS points of known joint measurement standards of the land elevation, find the line with the fitting equation in the region, and then incorporated into the calculation of GPS locator, access to plane coordinate points to be determined at the same time, get the point of normal height, so that the measurement accuracy, point density and operating efficiency is greatly improved, for the airport construction projects to provide accurate and reliable measurements.

2, the positioning of stands Coordinate Measuring Machine apron is an important part of NOTA
