Embodiment Construction
[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0049] see figure 1 As shown in the schematic diagram of accompanying flight initialization control, the target spacecraft 100 is located in a nearly circular earth orbit with an eccentricity close to 0, and is in a passive motion state. The tracking spacecraft 200 is gradually approaching the target spacecraft 100 along the gradually changing ellipse line (dotted line in the figure) behind the target spacecraft 100, and it is expected to establish a long-term and stable companionship in the rectangular accompanying flight area 300 behind the target spacecraft 100. fly state.
[0050] The accompanying flight initialization control method in the present invention refers to the process of controlling the tracking spacecraft 200 to change from the approaching state to the accompanying flying state. The approaching state of the tracking spacecraft 200 is a stat...
