Embodiment Construction

[0021] Such as figure 1 As shown, a method for determining the attitude of a spin-stabilized meteorological satellite based on a rough-fine attitude relationship model described in an embodiment of the present invention includes the following steps:

[0022] Step 1: Calculate the rough attitude of the satellite:

[0023] Step 1.1): Carry out quality inspection on the obtained satellite telemetry data in units of frames, and judge the quality of each frame of satellite telemetry data according to the synchronization code of the frame header and the check value of the frame tail. If the frame header and frame tail do not meet the requirements, it is deemed If the quality is not up to standard, it will be discarded;

[0024] Step 1.2): For the satellite telemetry data frames that have passed the quality inspection of step 1.1 and meet the requirements, decode according to the format definition of the satellite telemetry data, and store the values ​​of each channel into the speci...

Abstract

The invention relates to a determination method for attitudes of a spinning stabilized meteorological satellite based on a coarse-fine attitude relation model. The method is characterized by comprising the following steps that 1: the coarse attitude of the satellite is calculated; 2: a random error in the coarse attitude of the satellite is eliminated; and 3: the coarse attitude is modified by utilizing the coarse-fine attitude relation model. The method has the benefits that 1, the precision is high, and a calculated fine attitude result is basically consistent with the practical fine attitude of the satellite; 2, the applicability is high, and the fine attitude of the satellite can be calculated by the method to achieve accurate positioning of an observation cloud picture when the fine attitude cannot be obtained within 24h after attitude orbit control of the satellite or in an area observation mode; and 3, a processing procedure is distinct, the operand is not great, and implementation is facilitated.

Description

technical field [0001] The invention belongs to the field of meteorological satellite observation image positioning, and in particular relates to a method for determining the attitude of a spin-stabilized meteorological satellite based on a coarse-fine attitude relationship model. Background technique [0002] Accurate attitude determination is the basis for the precise positioning of meteorological satellite observation images and the basis for the application of meteorological satellite observation images. At present, my country's spin-stabilized meteorological satellites rely on the disk image to derive the satellite's precise attitude parameters to locate the image for the next 24 hours. This method is accurate in positioning and has been widely used in business. But this method can't deduce the precise attitude of the satellite, and can't realize the precise positioning of the satellite cloud image when the image is not collected or the disk image data accumulated is i...
