Embodiment Construction
[0024] refer to figure 1 , figure 2 , image 3 . According to the present invention, (1) establish a spring-mass system model: the agile imaging satellite earth observation demand planning is abstracted into a spring-mass system, based on Hooke's law and force balance, it is established by a spring with a length L connected to the slider Spring-mass system model. The stiffness coefficient of each observation task is determined according to the geographical location of the observation target and the orbit of the satellite, and the relationship between the comprehensive angle of the agile imaging satellite's earth observation and the time difference between the observation time and the overhead time is abstracted as the elastic force and spring compression / tension in the spring-mass system The spring-mass system model is established based on the relationship between the lift length and the rest length of the spring, and the movable range and slider length of the mission slid...
