Update: Here at ESA, we know that when it comes to launches, timing is everything. To ensure the best possible outcome, we've decided to change the timing of the launch of the Galileo documentary to after the summer. Stay tuned for updates and a new 'launch' date.
🧭 What's it like to attend a navigation conference?
Last week, we were at the European Navigation Conference in Vienna, Austria.
While there, we dived into the future of navigation with partners from industry, academia and government.
Follow us through a day at the conference here ⬇️
🛰️ A European first! ESA’s Celeste broadcasts first navigation signal from low Earth orbit.
Sent from Celeste IOD-1, the signal is the first dual-frequency navigation message in the L- and S-band, the first sent from a European satellite in low-Earth orbit.

The global geodesy supply chain underpins modern satellite functioning by providing the reference data satellites need to know where they are and where to point.

April was a busy month for @esa.int!
🛰️ We’re particularly proud of the Celeste IOD satellites, which broadcast their first navigation signals.
Check out this moment and other highlights from April 👇

Thirty years ago, Europe set out to build an independent navigation system. “Finding Our Way: Inside the Galileo Project” goes behind the signal that guides us all.

🛰️ Galileo's second generation will feature intersatellite links, which will allow the satellites to ‘talk’ to one another in orbit.

🛰️ Good morning Celeste, we hear you loud and clear!
Last night, ESA’s second Celeste satellite sent its first dual-frequency navigation message in the L- (🔴) and S-band (🔵) from low Earth orbit.
Congratulations to the teams around Europe that connected in the early hours to make this happen!

During #Artemis II's Moon flyby there were around 40 minutes without contact back to Earth📶 🌍️
@esa.int 's Moonlight aims to fill this gap by deploying a constellation of communication and navigation satellites around the Moon to never lose connection when most needed 🌑

The second generation of Galileo, Europe’s satellite navigation constellation, is being built. These satellites will feature reconfigurable payloads, provide more robust and reliable positioning, navi...
