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...
