Satellite-Tracking Antenna Stabilization via Dynamic Elevation Control

The patent implements dynamic control of the elevation angle by continuously adjusting it based on real-time satellite position information and reception signal quality. The system transitions from a static fixed elevation angle to a dynamic adjustable elevation angle that adapts to changing conditions, allowing the antenna to maintain optimal tracking without entering the keyhole problem zone while ensuring communication quality is preserved through active signal quality monitoring and adjustment.

The patent solves the keyhole problem by changing the operational parameters (elevation angle limits and driving torque characteristics) rather than adding hardware components. The system modifies the elevation angle range to avoid problematic zones and adjusts the driving torque parameters to compensate for the reduced degree of freedom, thereby eliminating the need for additional motors while maintaining system reliability and avoiding increased weight.

The patent avoids increasing antenna volume by implementing software-based parameter adjustments rather than hardware expansion. The system modifies elevation angle operational limits and driving control parameters to prevent keyhole problems, eliminating the need for additional motors that would increase the antenna's physical dimensions while maintaining effective satellite tracking capability.

The patent reduces power consumption by optimizing the driving torque parameters and elevation angle control rather than adding more motors. The system adjusts operational parameters to work efficiently within the existing motor capabilities, avoiding the increased energy demand that would result from operating multiple high-power motors simultaneously while still effectively preventing keyhole problems.
