Ep. 14 衛星操控還要看太空天氣?
在2022年,已經發射幾百顆的星鏈衛星 (Starlink),因為地球磁暴而掉落近40顆剛發射的衛星,造成虧損達到約新台幣14億元。此次事件之後人們逐漸意識到低軌衛星很容易受到太空天氣的影響,因此紛紛引入各式的模式要來精準計算這些軌道,以及可能受到的外力。目前科學家們已經有許多不同的模式可以進行計算大氣密度,因此可以推算衛星可能受到的阻力,進而了解這些衛星會如何改變其角度。由於近期衛星發射的數量極多,並且又以低軌衛星為最大宗,世界各國將會需要一個精確的模型來計算衛星軌道,並達成衛星使用最大化的結果。 參考資料: Satellite operators want better space weather models - SpaceNews -- Hosting provided by SoundOn
