Cornell University Researchers Demonstrated GPS Vulnerability with Spoofing Activities康奈爾大學的研究人員證明全球定位系統的脆弱性與欺騙性活動
Nowadays GPS (Global Positioning System) usage is so common with almost all high end cellular phones are embedded with GPS receiver module.如今GPS （全球定位系統）的使用是如此普遍，幾乎所有的高端手機都嵌入了GPS接收機模塊。 While it brings convenience to daily life, but too much relying on it may potentially cause serious issue in certain scenario.雖然它帶來的便利生活，但過於依賴它可能會導致嚴重的問題，在某些情況。 Just recently, a team of researchers from Cornell University have demonstrated a way on how to fool the GPS units by sending out false signal that imitate actual satellite signal patterns.就在最近，一個研究小組由美國康乃爾大學已經證明的方式就如何愚弄的GPS單位發出了錯誤的信號，即模仿實際的衛星信號模式。 Those signals will be interpreted by the GPS receivers as a genuine signal which causes the wrong position information being retrieved by end users.這些信號將被解釋的GPS接收機作為一個真正的信號導致錯誤的位置信息檢索的最終用戶。 For normal consumers, it may be still alright but the consequence could be very serious especially when such a scenario happens in military applications.對於一般的消費者，它可能仍然不錯，但其後果可能是非常嚴重的尤其是當這種情況發生在軍事上的應用。
GPS receiver is capable to lock to at least four satellites orbiting around the earth to obtain accurate positioning information through specific pattern signals. GPS接收機能鎖定到至少4顆衛星軌道環繞地球，以獲得準確的定位信息通過特定模式的信號。 But somehow these signals can be duplicated by this programmable transmitter, putting the whole system reliability questionable.但不知這些信號可以重複這一可編程發射機，使整個系統的可靠性值得懷疑。 Although existing transmitter is quite large in size, about the size of a suitcase, but it is foresee that the size can be shrunk down as small as a cigarette pack, making the proximity attack possible anywhere without the users’ acknowledgment.雖然現有的發射機是相當大的規模，大小相當於一個手提箱，但它是預見到的規模可縮小下跌的一小部分捲菸包裝，使盡可能接近攻擊沒有任何用戶的認可。 Just imagine how dangerous would it be if this tiny device can jeopardize the whole rescue effort when a rescue team has been dispatched but unable to identify the right location due to wrong GPS data.試想一下，如何將它的危險，如果這個小裝置可以危及整個救援工作時，救援隊已被派往但無法確定正確的位置由於錯誤的GPS數據。
Hopefully the demonstration and study results will trigger the way how GPS designers defining their next generation GPS products with a more thorough and full proof GPS release to the market in short future.希望的示範和研究成果將引發全球定位系統的方式如何確定其設計下一代GPS產品更透徹，充分證明全球定位系統釋放到市場在短期的未來。
