Abstract
The present disclosure provides satellite tracking systems and tracking methods. The satellite tracking system includes an array of antenna elements and a control unit. A feed current for each of the antenna elements passes through a phase shifter. The control unit generates a control signal for the phase shifter. The satellite tracking system searches, positions, and tracks a target satellite in accordance with the control signal. The satellite tracking systems and methods utilize step scanning and particle swarm optimization in the search stage, compensating for gaps formed during the satellite searching in the positioning stage, and conical scanning in the tracking stage.
Claims13
A satellite tracking system, comprising:
- an array of antenna elements, wherein a feed current for each of the antenna elements passes through a phase shifter;
- one or more processors;
- and
- one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions operable when executed by the one or more processors to cause the satellite tracking system to generate a control signal for the phase shifter, wherein the satellite tracking system searches, positions, and tracks a target satellite in accordance with the control signal.
A satellite tracking method, comprising:
- providing an array of antenna elements in a satellite tracking system, wherein a feed current for each of the antenna elements passes through a phase shifter;
- generating, by a control unit of the satellite tracking system, a control signal for the phase shifter;
- searching, by the satellite tracking system, for a target satellite in accordance with the control signal;
- positioning, by the satellite tracking system, the target satellite in accordance with the control signal;
- tracking, by the satellite tracking system, the target satellite in accordance with the control signal;
- and
- determining, by the control unit, whether an azimuth angle and an elevation angle of the target satellite are within a predetermined range, and if affirmative, determining whether a signal of the target satellite is within a communication range, and if otherwise, returning to searching for the target satellite in accordance with the control signal.
