Problems solved by technology
Since the high-orbit target passes through a certain "convergence point" only once in each orbital period, the time distribution of the measurement data corresponding to this method is poor, which is not conducive to quickly determining the target orbit and improving the accuracy of orbit determination

Embodiment Construction
[0087] Below in conjunction with accompanying drawing, technical solution of the present invention is described in further detail:
[0088] The implementation scheme of the present invention is mainly composed of four parts: airspace search parameter modeling, search airspace grid sequence establishment, search airspace grid sequence and search time series mapping, and search observation plan generation.
[0089] (1) Constructing the airspace search parameter model of the detection object
[0090] Aiming at the orbital motion characteristics of medium and high orbital targets, an airspace search parameter model is established consisting of sub-satellite point longitude and latitude range, search direction, search step size, reference altitude, step time interval, step switching time and other parameters. in:
[0091] 1. The latitude and longitude range of sub-satellite points [(L, B) s ,(L,B) e ] Define the rectangular search space for the detection object, (L,B) s Indicat...

The invention belongs to the technical field of space situation awareness, and particularly relates to a ground-based large-view-field photoelectric telescope search observation plan generation method. The core of the method is to make full use of the advantage of high efficiency of large-view-field wide-area search of a ground-based telescope, and the method mainly comprises the following steps: carrying out parametric modeling on a detection object area and a search strategy, and carrying out definition description on a wide-area search plan making task based on parameters; based on the size of the view field of the telescope, grid processing and sorting are carried out on the wide-area search range; performing search grid mapping for each stepping timestamp by integrating conditions such as spatial visible constraint, sky shadow constraint and moon background constraint; and summarizing each group of'timestamp-search grid 'combinations to generate a final equipment stepping search observation plan. According to the method, the limitation of a traditional search method based on'rendezvous point 'observation is overcome, the distribution quality of the observation target orbit measurement data can be effectively improved, and the method has very high pertinence and practical operability for medium and high orbit space debris search and detection.
Description
technical field [0001] The invention belongs to the technical field of space situational awareness, and in particular relates to a method for generating a search and observation plan for a ground-based large-field photoelectric telescope. Background technique [0002] At present, space is undergoing a transformation. The deployment of giant constellations is accelerating, space debris is increasing sharply, space is becoming more and more crowded, and it is becoming more and more difficult to enter, exit and use space. The collision probability of spacecraft is increasing, and events such as collision and disintegration occur from time to time. The demand for space situational awareness such as on-orbit asset security protection and space traffic management is becoming stronger. The use of photoelectric telescopes to detect and catalog space debris is an effective means to accurately grasp the orbital movement of space debris and detect collision risks in a timely manner.
