%X DEM reconstruction is a step in data processing of spaceborne InSAR, its error is influenced by baseline error and GCP, etc. In this paper, DEM reconstruction method using GCP based on classic one was presented. To the reconstruction methods, the tranferring relationship between reconstruction error and baseline error was analyzed. The relationship shows that the requirement on orbit measuring precision is exigent, but when using GCP, in the situation of the same orbit measuring precision, the reconstruction error is reduced. In order to reduce the requirement on orbit measuring precision and at the same time to keep reconstruction precision, GCP should be used. In addition , the transferring relationship can direct designing some parameters of the system.
