歐洲EGNOS定位系統更加準確

Filed under: GPS衛星定位


[撰文:icebin]

我們現在用的GPS定位系統基本上基於美國衛星,而最近,歐盟在10月1日發射了一顆免費的導航衛星EGNOS,可以將美國GPS導航衛星的準確度提高兩公尺,目前,美國GPS的定位準確度為七公尺。

EGNOS是由三個同步衛星,以及40個定位基地台和4個中央控制中心組合的地面網路所構成,EGNOS系統可以為空中航線提供垂直引導,同時可以為各類使用者、系統提供介面,歐洲航空、非航空使用者都可以享受到它的便利,在未來,EGNOS將帶來更安全更低成本的民用導航應用。

話說回來,我們的GPS手機也該升級了,經常出現車輛在河中跑、或穿山越嶺的現象,雖然這和數位地圖也有關係,但多了一種衛星定位系統,使用者也將多一種選擇。
