自1994年美国全球定位统全部建成并投入运行以来,短短的几年中,这一技术发展极为迅速。因此就需要尽快的将GPS测得的数据准确的转换为实际测量所必须的数据。本文阐述的主要内容为GPS网平面坐标之间的转换以及其精度评定,从而以利于GPS在工程测量等测量工作中的快捷的应用。 Since the United States established its global positioning system in 1994 and put it into operation, in just a few years, this technology has developed rapidly. Therefore, it is necessary to quickly convert the data measured by GPS to the data necessary for the actual measurement. The main content of this paper is the conversion of GPS network plane coordinate and its accuracy evaluation to facilitate the rapid application of GPS in surveying work such as engineering surveying.
