Space exploitation is one of the most important areas in human's activities in the 21st century. In the next 20 years, application satellite and satellite application is still the dominant field in space exploitation. It will make great influences on human society, economy and military. Considering China's national situation and based on the past 40 years of experience, the author proposes suggestions for the technique way of satellite engineering. T6 build-up some application satellite systems for long-term stable operation is the main target among all. The application satellite will be the base of such systems. Satellite engineering design has to be done from top level with considering simultaneously the large system and the integration of space and ground segment. The shortcut of developing satellite is to use common platform and to use the parts of three standardization (generalization, serialization, modularization). So the satellite products can be obtained with a faster, better and more e-conomic results. To narrow the gap with the international technique level, China has to strengthen the prestudy, attach importance to technical innovation, develop new platform, new payload and new satellite, and realize the development with a jump step. To achieve these goals the operation mechanism and management pattern should be reformed and the translation from the research institute system to modern enterprise system should be realized.
