Review on the Development and Technology of Operationally Responsive Space

Earth observation satellites provide important information security for modern military activities. In the future war, who achieves the initiative of space battlefield will directly affects the process and outcome of the war. By analyzing the development and application of typical plans and tests of the Operationally Responsive Space (ORS) such as the TacSat plan, System F6 Program and "100-Satellite Constellation", and its content, key technology and expected target of ORS can be organized and extracted. Through comparing the experimental results for several generations of test products, it demonstrates that the idea of ORS will influence the development of the theory and practice on space operations and joint operations in the future, which will play a decisive role in the future war and put forward new ideas for the development of satellite system.
