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 or-der 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 applica-tion of LEO remote sensing satellites.
