摘　　要：结合莆田市GPS复测控制网解算的需要,研究和计算分析了基准站数量和分布对莆田市GPS复测控制网解算的影响。结果表明:基准站选取对区域GPS控制网整体解算精度影响较大,选择WUHN站和均匀分布在莆田市四周的4个CORS站和1个网中CORS站作为基准站,能使控制网解算结果达到较高的精度。For resolving the GPS repeating control-network of Putian,we studied and analyzed the number and the spatial distribution of the base stations that influenced the precision of result in this paper. The results indicate that the selection of the base stations affected the precision when resolving the region GPS control-network seriously,but the precision could be improved by selecting the station of WUHN,four CORS stations around in the city of Putian evenly and one station in the control-net as the base station.
