Method for fully-automatically catching near earth and medium and high orbit space targets in real time

Abstract

The invention discloses a method for fully-automatically catching near earth and medium and high orbit space targets in real time. The method comprises the following steps of: (1) acquiring forecast information according to a known orbit space target, and making a telescope reach a preset position to wait; (2) before the orbit space target reaches, moving the telescope along the moving speed direction of the space target in advance, acquiring a charge coupled device (CCD) image during movement so as to outstand the distinction degree of a fixed star and a space target star on the CCD image; (3) performing real-time all-visual field scanning on the acquired image to obtain the suspect space target; (4) using the prior information of a known orbit to discriminate to obtain the correct space target; and (5) automatically catching the space target and precisely tracing the space target. An optical observation telescope can automatically catch, trace and measure the near earth and medium and high orbit space targets in real time by the method under the condition that the optical observation telescope is not manually interfered. The method is good in practical processing effect and can be widely applied to the monitoring on the near earth and medium and high orbit space targets.

Description

technical field [0001] The present invention is a method of using an optical telescope equipped with a CCD camera to automatically capture space targets in known orbits near the earth and middle and high orbits in real time. It uses the CCD image obtained by the optical telescope to identify near Earth and medium-high orbit space targets, and automatically capture and track them precisely. Background technique [0002] Since the first Galilean optical telescope was invented, the optical telescope has been the most important tool for human beings to explore space, and it has promoted the development of astronomy for 400 years. In the past half a century, with the launch of artificial satellites, it has been widely used for space target observation and has become the main way to obtain space target information. The development of telescopes is changing with each passing day. In order to adapt to different tasks, various optical observation systems emerge in an endless stream,...

On the other hand, most of the stations that meet the optical observation conditions are located in relatively remote places with poor living and working guarantee conditions. This is an extremely serious contradiction with the astronomical observation needs that require widely distributed observation stations to obtain observation data. It is a helpless choice for stationed observers, and it also limits the scope of site selection
