Abstract

The invention discloses a quick traversing method of geosynchronous orbit targets based on a low-earth-orbit observation satellite. The quick traversing method comprises the following steps: Step I: determining an observation sequence, analyzing and calculating observation areas of two orbits adjacent to the observation satellite according to a whole observed geosynchronous corridor within 15-degree inclination in conjunction with an orbit of the observation satellite to realize a seamless spliced sequence track, Step II: determining window quantity of the single track, Step III: calculating maximum detection time capable of being guaranteed by each window according to the relative movement speed between the observation satellite and the observation sequence track of the geosynchronous corridor, and Step IV: forming ground injection data to ascend to be injected into the satellite. The method can effectively cover the shortage of foundation detection traversing equipment in fixed time, a fixed space and a fixed detection area, and has a higher reference significance in traction satellite attitude track tracing and independent task planning implementation.

Description

technical field [0001] The invention relates to a method for quickly traversing geosynchronous orbit targets, in particular to a method for rapidly traversing geosynchronous orbit targets based on low-orbit observation satellites. Background technique [0002] As the satellite orbit with the most application value, the geosynchronous orbit belt has limited resources and has important military and civilian values. At present, it is mainly detected and cataloged by radar or photoelectric large-scale equipment in a fixed area on the ground. Due to the limitation of the curvature of the earth and the fixed observation area, it is impossible to achieve long-term detection. At the same time, it does not have the detection capability of the full geosynchronous orbit. Detection over our country. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for quickly traversing geosynchronous orbit targets based on low-orbi...
