It briefly introduces the international development status of the high resolution for air-to-ground remote sensing satellite. High resolution for the air-to-ground observation is also the civil and martial pursuing target. Because of the rising cost along with the large-diameter telescope, the weight, cubage will also become large. Nowadays, how to get high resolution with light weight, small cubage launch and large diameter is one of the important research directions in many countries. We raise a method of large field-of-view and high resolution optical synthesis telescope which can solve this problem. It is a co-phased segment mirrors which synthetic aperture diameter is about 1 m. Four 50cm diameter segment mirrors can fulfill the requirement. It is folded during its launch and is spread after it reaches to its working spot. In this way, it can reach the requirement of low launch weight, small launch cubage and can get high resolution observation. This method contains the key technologies of real-time UV coverage, optics design optimization, co-phase measurement and adjustment, micro-displacement sensor technology, the optics design and structure design. We explore the technology which can fulfill field-of-view of 1.86°and the resolution of 0.4m. We will discuss the UV-coverage method which includes the aperture arrangement, the relationship between the aperture number and the synthetic aperture diameter. There are much more detail calculation and analysis to it. Something is discussed about its structure design and optics design in the paper. © 2010 SPIE.
