- W4324118378 abstract "The application of medium elliptical orbit satellites in the field of optical remote sensing is becoming more and more extensive. In order to improve the satellite's on-board autonomy, this paper proposes a strategy for on-orbit autonomous adjustment of camera imaging parameters suitable for global full-time detection of targets. In this paper, both the irradiation environment and mission efficiency are considered at the same time, and the orbit is optimized to reduce the ionizing radiation dose of high-energy protons from the source. The orbit is in the form of injection into the orbit base point, and the J2 model is used for orbit recursion 1 hour before and after the base point. Then, according to the requirements of the satellite in-motion imaging mission, considering the influence of orbit altitude change, observation target position, observation target surface temperature, and taking into account the limitations of on-board storage, the on-orbit calculation method of TDI line period, focus, gain and integration time is finally given. Using this method can improve the imaging quality of in-orbit remote sensing satellites, enhance the operational flexibility and on-board autonomy of satellites, and reduce the number of injections on the ground." @default.
