Abstract
GPS technology is one of the fastest growing technology in today's information society, GPS positioning technology for its speed, precision degree is high, the all-weather, without being limited by the visibility conditions, cost, simple operation and other excellent features are widely used in large ground control survey. Today, to say the GPS positioning technology has pletely replace the conventional measuring Angle, measuring means to establish the work. We usually apply the GPS satellite positioning technology based GPS is . Can be roughly classified into the work can be divided into two categories: a class of high precision work is global or national, its main task is to as a global high-precision coordinate frame or by the national high precision coordinate frame, for global geodynamics and space science scientific research work of the service, or to the research of regional tectonic movement or crustal deformation law and so on. Another kind is a regional work, including the city or area work, GPS work, etc., this kind of the distance between adjacent points in for a few miles to a few tens of kilometers, its main task is to directly serve the national economic construction.
Based on the field to make use of GPS data acquisition, and it is concluded that using GPS measurement with high efficiency and cost save.
Key words: GPS,Engineering surveying,GPS static positioning measurement,Real-time dynamic GPS positioning
