衛星通信（Satellite Communication）是指利用人造地球衛星作為中繼站，實現地球表面或空間用戶之間遠距離信息傳輸的技術系統。其核心原理是通過衛星上的轉發器接收、放大并轉發來自地面站的信號，以覆蓋廣闊的地理區域。以下是衛星通信的詳細解析：
衛星通信系統由三部分構成：
信號傳輸遵循“上行鍊路-衛星處理-下行鍊路”流程，典型延遲為250-300毫秒，符合國際電信聯盟（ITU）《無線電規則》标準。
當前挑戰包括頻譜資源競争、雨衰效應（Ku/Ka波段尤為顯著）及高軌衛星延遲。最新進展聚焦：
衛星通信技術持續推動全球化信息互聯，相關标準及案例可參考國際宇航科學院（IAA）發布的《衛星通信白皮書》及IEEE《航天器與衛星系統期刊》研究成果。
衛星通信（Satellite Communication）是指利用人造地球衛星作為中繼站，在地面、空中或太空中的兩個或多個終端之間傳輸信息的通信技術。以下是詳細解釋：
衛星通過接收地面站發射的無線電信號，經放大和頻率轉換後轉發至目标接收端。整個過程依賴衛星的星載轉發器和天線系統，信號傳輸路徑涉及上行鍊路（地面→衛星）和下行鍊路（衛星→地面）。
低軌衛星星座（如Starlink、OneWeb）正通過大規模部署小型衛星降低延遲并提升帶寬，未來或實現全球無縫高速互聯網覆蓋。
