欧空局Celeste低轨导航演示星3月25日首飞
原标题：Celeste: Countdown to Launch 1
欧空局LEO-PNT在轨演示任务Celeste的首批两颗立方星IOD1-2将于3月25日由Rocket Lab电子号火箭在新西兰马希亚发射场发射，分别由GMV和泰雷兹阿莱尼亚宇航牵头的两个欧洲联合体研制，将验证下一代导航技术与新增频段，为欧洲未来低轨导航运行系统铺路。
推荐理由欧洲低轨导航星座首次在轨演示，与北斗、低轨星座竞争格局直接相关。

Celeste: Countdown to Launch 1
On 25 March, the first two satellites of the Celeste in-orbit demonstration mission will lift off aboard Rocket Lab’s Electron rocket from the company’s Māhia Launch Complex in New Zealand.
Celeste will play a pioneering role in elevating the future of Europe’s satellite navigation capabilities.
As ESA’s initiative for satellite navigation in low Earth orbit (LEO-PNT), the mission will be testing next-generation technologies and add new frequency bands for satellite navigation to inform the deployment of a future European operational navigation system in low Earth orbit.
The mission will begin with two demonstrator satellites, IOD1-2, to secure and test the assigned frequency filings and transmit representative navigation signals until the end of the year.
The two satellites consist of two CubeSats (12U and 16U respectively), both developed by two consortia composed by a wide set of European players, one led by GMV (Spain) and the other led by Thales Alenia Space (France).
