Research on All-time Online TT&C Technology of LEO Remote Sensing Satellite

This paper analyzes the four anytime requirements for LEO remote sensing satellites to realize all-time online. In order to adapt to the practical needs of flexible operation and rapid response of the satellites, it proposes a plan to carry out space-based TT&C based on the Tiantong-1 high-orbit mobile communication satellite. It also compares and analyzes the characteristics of various TT&C methods. The paper puts forward some assumptions,such as constructing the space-based integrated TT&C service system, developing the multi-method integrated TT&C terminal, optimizing the remote sensing satellite classification and operation strategy, and analyzes the overall feasibility. It explores a development path for realizing all-time online and anytime control application of LEO remote sensing satellites.
