Observation method and system for minute-level rapid traversal of high-orbit target

Abstract

The embodiment of the invention relates to an observation method and system for minute-level rapid traversal of a high-orbit target, and the method comprises the steps: setting the observation capability of an observation system according to the combination of an observation region and a coverage demand for an observation target; sending the observation system to a quasi GEO orbit as an initial observation point; constructing a multi-satellite observation system with the total number of satellites being N by taking the initial observation point as the standard, wherein the system is a constellation evenly distributed on the quasi GEO orbit; if the track inclination angle i is equal to 0 degree, completing the system construction; and if the inclination angle i is not equal to 0, carrying out adaptive maneuvering of the platform attitude, so that the visual axis of each observation point points to a 0 degree synchronous belt area. The observation view field of the multi-satellite observation system forms a gap-free observation screen covering the GEO zone by 360 degrees in real time in the GEO area, the track of the GEO target can be completely covered by the gap-free observation screen, and the observation method enables the traversal observation period of high-orbit space debris and the target to enter the minute-level magnitude.

Description

technical field [0001] The invention relates to the technical field of space target detection, in particular to an observation method and system for minute-level fast reading traversal of high-orbit targets. Background technique [0002] Due to the significant advantages of geosynchronous satellites in the fields of remote sensing, communication, and navigation, high-orbit satellites usually have great application significance and are high-value space assets. High-orbit space debris poses a great threat to the safety of high-orbit satellites, especially for non-geostationary satellites. Once a collision occurs, the satellite may cause major adverse consequences such as premature failure of the satellite. Therefore, comprehensively monitoring the distribution and changes of high-orbit debris and targets can provide timely debris threat early warning information for high-orbit satellites, which is of great significance to ensure the safe operating environment of high-orbit sat...
