Embodiment Construction

[0037] A method of orientation to the sun based on the current information of the solar panel, which mainly includes two parts: the search for the sun and the orientation to the sun. The current value is the current value of the solar panel. When the sun and the initial attitude current value of the star do not meet the conditions, the process of sailboard alignment to the sun through the fast capture process or the 360-degree capture process can reduce the time for orientation to the sun; Judging the star attitude current value adjusted by the sun search, so as to orient the sun, the overall process is as follows figure 1 As shown, the specific steps are:

[0038] The first step is to start the sun search process, measure the current value under the initial attitude of the star, and record the initial attitude data of the star at the current moment, as the basis for subsequent capture;

[0039] In the second step, according to the preset search current threshold set in advan...

Abstract

The invention discloses a sun orientation method based on solar panel current information. Satellite sun orientation is realized based on solar wing current information. The current information of a solar panel is utilized to control the rotation of a star body, so that the sun angle of the panel is controlled within a required range, the problems that the traditional sun sensor used on orbit is easy to be abnormal after being installed and cannot realize sun alignment are solved, and the sun orientation can be realized under the condition of not increasing the installation number and cost ofthe sensors.

Description

technical field [0001] The invention relates to a method for orientation to the sun based on current information of solar panels, and belongs to the field of attitude determination of spacecraft. Background technique [0002] In the energy security mode of the three-axis earth-facing satellite, the solar wing is usually rotated to a specified angle first, and then the satellite attitude is controlled by the sun sensor on the star or the solar wing so that the normal line of the solar wing points to the sun as much as possible to ensure the energy of the satellite. The actual output current of the solar wing = the theoretical maximum current of the solar wing * cosθ, θ is the angle between the normal of the solar wing and the sunlight vector, and the value range is 0-180 degrees. When θ≥90 degrees, the actual output current of the solar wing is 0. [0003] The sun sensors commonly used in orbit include 0-1 sun sensor, digital sun sensor, and analog sun sensor. Although thes...
