Embodiment Construction

[0014] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the present invention, modern satellites are used as examples of observation targets, but this is not limiting, and any synchronous orbit space objects (hereinafter referred to as space objects) with different attitude stabilization methods including modern satellites can be used as this object. Invented observation target.

[0015] For space objects, there are differences in their photometric characteristics under different attitude stabilization methods. Specifically, in the spin-stabilized mode, since the space object rotates around the central axis at a high speed, it will cause the average effect of the surface brightness. Therefore, the change range of the surface brightness value of the space object in the spin-stabilized mode is smaller than that in the three-axis stabilized mode. Based on this difference, the inventor of the present...

Abstract

The invention relates to a method for judging a synchronous orbit space object attitude stabilization mode, in particular to a method for judging a synchronous orbit space object attitude stabilization mode based on photoelectric observation. The method for judging the synchronous orbit space object attitude stabilization mode comprises the following steps that luminosity information of a space object is obtained, wherein the luminosity information of the space object is obtained by adopting a photoelectric observation means; the time length of obtained observation data and the number of data points are checked; the observation data are smoothly fitted; the attitude stabilization mode of the space object is judged.

Description

technical field [0001] The invention relates to a method for judging the attitude stabilization mode of a space object in a synchronous orbit, in particular to a method for determining the attitude stabilization mode of a space object in a synchronous orbit based on photoelectric observation. Background technique [0002] For a space object such as a satellite, its attitude stabilization method is an important feature. When designing, observing, and controlling a space object, it is often necessary to determine the attitude stabilization method of the space object. Taking modern satellites as an example, their attitude stabilization methods are mainly spin stabilization and three-axis stabilization. The three-axis stabilization method can make space objects maintain a standard orientation, while the spin stabilization method can make space objects rotate around the central axis. High speed spin. Different attitude stabilization methods will lead to differences in the satell...
