Abstract: Satellite remote sensing has become the main method of global earth observation. In this paper, the geodetic satellites are briefly summarized at first. The contribution and problems of satellite photogrammetry of China are specially analyzed. The development trend of earth observation satellites is analyzed, and the emphases are on the possibility and technical bottlenecks of comprehensive surveying and mapping satellites with integrated payloads. It is generally considered that the observation efficiency is high with single integrated surveying and mapping satellite, while the overall observation benefit is limited. The possibility and key technologies of earth observation with intensive micro satellite constellation are analyzed, including payloads modular design, satellite miniaturization design, satellite optimal configuration technology, data transmission technology, the elastic allocation technology for satellites in-orbit and on-board data fast processing technology etc. The prospective of intelligent observation satellite is prospected, and the corresponding key technologies are analyzed, including the technologies of on-board observation intelligent identification, inter-satellite and satellite-earth intelligent transmission, on-board and ground intelligent data processing, etc. In addition, the intelligent obstacle avoidance of satellite, intelligent tracking and intelligent control of launch vehicle landing location are also the development directions to be considered in satellite observations.

Key words: space surveying and mapping, gravity satellite, magnetic satellite, optical mapping satellite, microwave mapping satellite, micro satellite networking, intelligent satellite observation
