Embodiment Construction
[0031] Below, combine Figure 1 to Figure 6 The present invention is further described.
[0032] A method for calculating the time when the satellite sun wing blocks the data transmission antenna to the ground comprises the following steps:
[0033] (1) According to the satellite star structure design, the geometric motion relationship between the satellite solar wing and the ground data transmission antenna beam and the geometric motion relationship between the satellite solar wing and the sun when the satellite solar wing blocks the ground data transmission antenna are obtained; The solar wings are distributed on both sides of the satellite and constantly rotate with the relative position of the satellite and the sun. Taking this implementation method as an example, the half-cone angle of the signal transmission beam of the ground data transmission antenna is 5°. When the solar wing enters this When within the range, the angle between the line connecting the ground data tra...

The invention discloses a method for calculating shielding time of a ground data transmission antenna by solar panels of a satellite. For the problem of calculation of the shielding time of the ground data transmission antenna by the solar panels of the satellite in satellite task planning, solar panel rotation, satellite attitude information, a satellite position and a ground station position are considered, and the method for calculating the shielding time of the ground data transmission antenna by the solar panels of the satellite is designed. The method comprises the steps of abstracting an action of shielding the ground data transmission antenna by the solar panel rotation into a space geometric relationship; then, building a model for the geometric relationship by utilizing a vector tool; and finally, inputting information such as the satellite attitude information, the number of instantaneous precision orbits of the satellite, the time of passing the ground station by the satellite, the ground station position and the like, performing calculation by utilizing data output by the model, and finally obtaining the shielding time of the ground data transmission antenna by the solar panels of the satellite. The method has the characteristics of high calculation efficiency, easy realization, easy expansion and good compatibility.
Description
technical field [0001] The invention relates to a calculation method for the time when a satellite solar wing blocks an antenna for ground-to-ground data transmission, and is particularly suitable for the problem of calculating the time for which a satellite solar wing blocks a ground-to-ground data transmission antenna in the field of satellite mission planning. Background technique [0002] Satellite attitude adjustments such as side swing and pitch are required during the execution of tasks such as playback, actual transmission, and recording while recording. At the same time, in order to better charge the battery, the solar wing also needs to rotate continuously according to the position of the sun. Therefore, this makes the satellite solar wing enter the field of view of the signal beam of the satellite-to-ground data transmission antenna under certain circumstances, which interferes with the communication capability between the satellite and the ground and affects the ...
