Space target identifying, positioning and tracking method

Abstract

The invention provides a space target identifying, positioning and tracking method which comprises the following steps: shooting the starry sky by star sensors on a satellite-in-orbit platform; transmitting photos to a ground information receiving device; transferring the photos to a data processing computer by the ground information receiving device for feature extraction, to obtain a fixed star map and identify the space target in the map at the same time; determining the space pointing of the star sensors loaded on the satellite platform when shooting, determining the position of the space target relative to the satellite platform; and determining the position of the space target in the photos in the space finally. On the basis of not affecting the initial tasks of the satellite, the satellite acts as the space target monitoring satellite; a general survey space target monitoring is realized by the unconscious information acquired by each satellite, the weaknesses of less special monitoring satellites and weak load monitoring capacity in our country are compensated on the advantages of amount and system, so as to construct a space-based space target monitoring system of China.

Description

technical field [0001] The invention relates to a space target recognition, positioning and tracking method, which belongs to the field of space technology and is used for detecting, tracking, orbit determination and forecasting, identifying and cataloging space targets. The invention also discloses a space-based space object monitoring system based on a star sensor. Background technique [0002] The space target surveillance system refers to the intelligence system that detects and tracks space targets, determines orbits and forecasts, identifies and catalogs them, and collects and analyzes them. It has the ability to monitor non-cooperative targets. Space objects refer to spacecraft and space debris operating in outer space. [0003] The space target surveillance system includes four parts: detection system, information processing system, communication system and time system system. The detection system mainly includes various surveillance radars, optical telescopes, las...

AI Technical Summary

Problems solved by technology

However, due to the large size of commonly used space target detection equipment (such as radars, optical telescopes, etc.), the design requirements for volume platforms are relatively high, making it expensive to design, develop and deploy a set of space-based space target surveillance systems. At present, only the United States has deployed a space-based space target surveillance system composed of 1 SBSS satellite in the world

Although the space target monitoring capability of the SBSS satellites of the United States is relatively strong in terms of the performance of a single satellite, the space target monitoring capability of the entire system is still very limited due to the limited number of SBSS satellites
