Satellite Beamforming Alignment for Global Network Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network communication technologies, such as terrestrial networks, fail to provide extensive global coverage, especially for civil aircrafts, ocean-going vessels, offshore cruise ships, and remote regions due to geographical restrictions and high deployment costs, limiting Internet access and wireless network services.
Innovation Solution
A communication method utilizing low-orbit satellites with antenna arrays that employ beamforming technology to determine and maintain alignment with a beam receiving end, ensuring continuous communication without geographical restrictions by adjusting the direction of arrival (DoA) of satellite beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If terrestrial network deployment is used, then network coverage can be provided in accessible regions, but it cannot achieve global coverage due to geographical restrictions and high deployment costs
Solution Approach 1:
The patent transitions from terrestrial (ground-based) network deployment to satellite-based deployment, moving the communication infrastructure from the Earth's surface to orbital space. This dimensional change enables global coverage without the geographical and economic constraints of ground-based infrastructure, allowing networks to reach remote oceans, skies, and inaccessible regions.
2Area of stationary object
If satellite communication is deployed, then global coverage can be achieved, but maintaining continuous beam alignment with moving receiving ends becomes complex
Solution Approach 1:
The system performs preliminary actions by pre-calculating satellite trajectories, predicting receiving end positions, and pre-adjusting beam directions before communication sessions begin. This advance preparation reduces the complexity of real-time alignment adjustments and maintains continuous connectivity despite satellite and receiver motion.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors the positions of satellites and receiving ends, measures beam alignment deviations, and automatically adjusts beam directions in real-time. This closed-loop control maintains optimal alignment without requiring complex manual intervention, solving the alignment complexity problem through automated adaptive control.
