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).
