隨著全球通訊技術的快速發展，以及低軌衛星（Low Earth Orbit, LEO）應用範圍的不斷擴大，低軌衛星成為提升網路韌性與通訊自主性的關鍵技術。低軌衛星具備低延遲、部署靈活與全球覆蓋等優勢，成為現代通訊網絡的重要組成部分。
本研究透過軌道模擬與數據分析，探討星鏈（Starlink）低軌衛星星系對台灣通訊韌性的影響，並評估低軌衛星技術在台灣星系的應用可行性。研究過程中，運用Ansys Systems Tool Kit (STK) 軟體模擬星鏈衛星運行模式，分析不同軌道傾角、衛星數量與地面閘道配置對台灣通訊可用性的影響。並提供台灣建立低軌衛星星系的策略與建議，以提升國家通訊自主性與網路韌性。
研究結果顯示，適當配置低軌衛星星系與地面閘道可顯著提升台灣的通訊可用性。此外，若能在鄰近地區（如石垣島）增設地面閘道，將進一步強化台灣的通訊韌性，確保網路穩定性，並在緊急情境下提供備援能力。
綜合上述分析，本論文亦彙整相關建議，提供未來台灣低軌衛星星系布建策略之參考，助力台灣在全球低軌衛星市場中佔據有利地位，確保國家資訊安全與通訊自主性。

The rapid growth of global communication technologies and the expanding use of Low Earth Orbit (LEO) satellites have made them a key solution for improving network resilience and communication autonomy. With advantages such as low latency, flexible deployment, and global coverage, LEO satellites are becoming essential to modern communication networks.
This study uses Ansys Systems Tool Kit (STK) to simulate the Starlink constellation and analyze its impact on communication availability in Taiwan. Different orbital inclinations, satellite counts, and ground gateway configurations are evaluated to assess their effects on Taiwan’s connectivity. The results show that proper satellite and gateway deployment can significantly enhance communication resilience.
Additionally, placing ground gateways in nearby areas like Ishigaki Island further improves redundancy and network stability. Based on the findings, this thesis proposes strategic recommendations for building a Taiwan-based LEO satellite constellation to enhance national communication capabilities and ensure information security.
The thesis also compiles key suggestions for Taiwan’s future LEO satellite deployment strategy to help the country gain an edge in the global LEO satellite market and safeguard national information security and communication autonomy.
