It can be used to real-timely supervise the construction quality of the roller compaction for filling engineering. The composition and applied characteristics of GPS system, and the key technique problem and solution of the design are discussed. The height accuracy of GPS system is analyzed and the preliminary application is introduced. KEY WORDS ：GPS; filling construction; quality control; integrated system; face rockfill dam Introduction At present , in the quality management of filling construction of the face rockfill dam，the quality control method of “dual controls”is mainly adopted, of which one is manually controling the parameters of roller compaction including thickness and roughness of filling layer and rolled times and rolled speed o f compaction machines,the other is inspecting the test hole sampling manually in the area. The method play a positive role in promoting domestic development of concrete faced rockfill dam. How ever, the traditional manual management mechanism can＇t meet the demands of mo- dern mechanized construction and schedule anymore, with increasing of scale of con- crete face rockfill dam. Concrete faced rockfill dam of Shuibuya project in Qing jiang River of Hubei Province, China,ranking first in dam height of the same type in the world, is as high as 233 m. The project has a total filling volume of 1. 6 ×107 m3 and more than 6×105 m3 for peak filling volume of a single month, so d
