At the initial stage of electric power engineering construction, quick and accurate establishment of measurement area control system matching with national coordinate system is the chief task of electric power engineering measurement. The advanced precise point positioning(PPP) of global positioning system(GPS) is proposed, of which the positioning principles are analyzed. The technical and economic comparisons are carried out with other positioning methods. The reliability of PPP is proved by test analysis and the application method is presented. It is shown that PPP has the advantages of flexibility of traditional point positioning method and high precision of relative positioning one. In addition, it can easily solve the initial coordinate problem of first stage control in electric power engineering measurement. Thus, the hard work to find national level control points can be avoided. Particularly under such special conditions of post-disaster reconstruction, the advantage of PPP is prominent.
