Abstract: In recent years, more and more types of domestic satellite sensors are available. There is a growing demand for production and research using autonomous and controllable domestic satellite images. The accuracy analysis of combined adjustment of multi-source domestic satellite images is important particularly. This paper introduces the situation of combined mapping production by using ZY-3 and TH-1 in the special difficult conditions,such as outdated situation, high noise, cloud coverage area and photographic gap. And the feasibility and accuracy of combined block adjustment without control with GCP for ZY-3 and TH-1 are verified.

Key words: ZY-3, TH-1, combined block adjustment, accuracy analysis, stereo mapping
