A system for observing space objects with high coverage

Abstract

The present invention relates to a system for observing space objects with high coverage, comprising: a console configured to perform the following actions: determine the observation lower edge of each observation satellite used for observing space objects, wherein each The tangent point of the observed lower edge of the observation satellite is determined to make the angle between the line between the tangent point and the center of the earth and the line between the satellite and the center of the earth be where N is the number of observation satellites; and determine the observation upper edge of each observation satellite; and N observation satellites, wherein each observation satellite is respectively at the determined orbital altitude, wherein each observation satellite has a plurality of telescopes, which are Oriented to have a respective field of view constituted by said observed upper edge and observed lower edge. Through the invention, the coverage rate of the observation constellation can be significantly improved, and at the same time, the telescope load of the observation satellite can be reduced, thereby improving the observation reliability and reducing the observation cost.

Description

technical field [0001] The present invention generally relates to the field of satellite monitoring of space objects, and in particular relates to a system for observing space objects with high coverage. Furthermore, the invention relates to an observation constellation with high coverage. Background technique [0002] In many fields such as scientific research, military affairs, national defense, and national security, it is necessary to monitor space objects such as meteorites, planets, flying objects, and space debris, so as to give the positions and changes of these space objects in the sky, Then determine the position of the space target, so as to calculate or correct its orbit. After obtaining its orbit, the precise position information of the space object can be obtained, so as to provide relevant information for the safe flight of the space spacecraft, or for other scientific research purposes or safety purposes. [0003] At present, the monitoring of space debris ...

Problems solved by technology

However, ground-based systems such as ground-based telescopes will be affected by weather and sunlight when observing stars and space debris, and the daily observation arc is limited, and the re-observation period for debris is too long; although ground-based radars are not affected by weather, sunlight However, it is limited by the geographical location, and after observing the debris, the next observation will take more than 12 hours. For the observation of space debris generated by sudden space events, it will take 8-12 hours to observe. For the aircraft in orbit the security of the
