| Abstract: | The compatibility problems for known point results is discussed using the results of GPS network adjustment directly,in order to eliminate a known point with gross errors.For short baseline(10～15 km below)of engineering surveying GPS network,it summed up the method of data processing and quality analysis for GPS engineering network surveying network.Taking observations of some railway engineering surveying control network for example,it made testing for data processing and quality evaluation.The results showed that: horizontal precision were better than 0.75 cm and 0.70 cm in the x and y direction respectively,and point precision was better than 0.90 cm;and baseline azimuth error was better than 0.94″,and the weakest side of the relative precision was 3.60 ppm.In a word,it obtained high accuracy and could provide reference for engineering applications. |
