摘　　要：为研究全球电离层模型（GIM） 和精密星历对GPS 测量控制网成果的影响, 以阜新市城市GPS 控制网为例展开相关研究.利用Trimble Total Control （ TTC） 软件对时段长度从10-360min 不等的观测数据进行处理.数据处理时采用CODE 的全球电离层模型, 以及广播星历/ 精密星历.实践证明, 全球电离层模型的引入可显著地提高精度, 卫星轨道的影响可以忽略不计.In order to studying influence that to GPS surveying control network, which by GIM and precision ephemeris, it taking GPS control network of Fuxin city as studying objects.Surveying data of different period length that 10 to 360min were analyzed by soft-ware Trimble Total Control.GIM of CODE, broadcast ephemeris or precise ephemeris were used during data analysis.The practical showed that precision could increase obviously after GIM was applied, the influence of satellite orbit could be ignored.
