Galileo 系統啟用

由歐盟主導的 Galileo 系統宣布啟用，提供早期服務 (Early Operational Capability)：「Galileo navigation satellite system goes live」。預定的 30 顆衛星已經打了 18 顆上去：

At this point, 18 of the planned 30 satellites are already in orbit.

在一般的使用下精確度可以到 4 公尺，相較於 GPS 是 15 公尺高出不少：

Using GPS, private users can navigate with a precision of up to 15 meters (m). Galileo offers a precision of up to 4m for its fully open service.

而商用與軍用可以到公分等級：

Commercial users and official government services can even receive a precision of a few centimeters. This is important, for example, for fully or partially automated planes, cars or ships.

之後應該會有同時支援兩套系統的設備出來... 手機應該也會有？
