Embodiment Construction
[0030] Aiming at the deficiencies in the prior art, the present invention provides a calculation method for tracking arcs of IGSO satellites to ground moving targets, which is suitable for IGSO satellites whose orbital positions change in real time, and considers ground elevation angle constraints, satellite antenna angle constraints, and target narrow beam antenna constraints, It can be applied to moving targets on the ground, and can be directly applied to moving targets on the sea surface by relaxing the elevation angle constraint. figure 1 Shown is the analytical flow chart of the method of the present invention.
[0031] The inventive method comprises the steps:
[0032] (1) Within the specified time period, determine the time interval and the corresponding moving target position information at each moment;
[0033] The position of the moving target can be a pre-designed value, or a real-time position predicted according to the positioning information in the actual proce...
