Embodiment Construction

[0098] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0099] In the present invention, unless otherwise specified, "arranged on", "arranged on" and "arranged on" do not exclude the presence of intermediates between the two. In addition, "arranged on or above" only means the relative positional relationship between two parts, and under certain circumstances, such as after the product direction is reversed, it can also be converted to "arranged under or below", and vice versa Of course.

[0100] In the present invention, each example is only intended to illustrate the method of the present invention and should not be construed as limiting.

[0101] In the present invention, unless otherwise specified, the quantifiers "a" and "an" do not exclude the scene of mu...

Abstract

The invention relates to the technical field of aerospace, and provides a task satellite scheduling method for an infrared LEO constellation. The method comprises the following steps: projecting an invisible observation angle range of a satellite to a target to earth surface to obtain an undetectable range Db; projecting the maximum detection distance L of the satellite to the earth surface and removing the undetectable range Db to obtain a detectable range D1; projecting the target to the earth surface, and performing detectable analysis of the satellite and the target; screening orbital planes according to the longitude range of ascending nodes of the orbital planes and the geographic position of the target; and screening a task satellite from the screened orbital planes according to the relative motion relation between the satellite and the target and observable conditions. The problems that in the prior art, calculation is complex, on-satellite resource overhead is large and task planning timeliness is low in the task satellite scheduling process are at least partially solved, task satellite optimization efficiency and timeliness are improved, and the method has application value for task satellite scheduling of an infrared LEO constellation and design optimization of the constellation.

Description

technical field [0001] The present invention generally relates to the field of aerospace technology, in particular to a task star scheduling method for an infrared low-orbit constellation. Background technique [0002] The infrared low-orbit constellation mainly detects and tracks faint targets in a deep cold background. Due to the unpredictability of the appearance of the target, the infrared constellation needs to complete the real-time system response after the appearance of the target. Therefore, the infrared low-orbit constellation is different from the general remote sensing constellation, and naturally has the task requirements of autonomous operation and real-time response. [0003] The faint and cold targets observed by infrared low-orbit constellations are also high-speed moving targets. The flight time can be as long as 30 minutes or more, and the flight distance can exceed 10,000km. Therefore, relay coordination between multiple satellites of the infrared low-o...
