🛰 Satellite navigation on holidays: "How far are we from the museum?" As you plan your route this summer, Galileo is probably helping you get there. Billions of smartphone users worldwide rely on Galileo for positioning, navigation and timing. ℹ️ www.usegalileo.eu/accuracy-mat... 📷 Unsplash
🛰️ Satellite navigation on holidays: Enjoying a boat trip? Galileo is here to keep you safe at sea. It contributes to international search and rescue operations through the COSPAS-SARSAT system. ℹ️ www.esa.int/ESA_Multimed... 📷 ESA–I. Stojkovic
🛬 Satellite navigation on holidays: Flying somewhere for your summer holidays? Did you know that EGNOS helps guide safe aeroplane landings in over 500 airports and helipads across Europe? Find out more about EGNOS 🔗 egnos-user-support.essp-sas.eu 📷: GSA
🛰️Two new Galileo satellites enter service Two new satellites, SAT 33 and SAT 34, have now officially joined Europe’s Galileo satellite navigation constellation, strengthening its capabilities, resilience and autonomy. www.esa.int/Applications...
The Earth emoji is doing its best 🌍 🛰️ But let's not forget the satellites orbiting overhead, powering positioning, navigation and timing, and so much more.
What has ESA been up to these past months? Propelling people around the Moon, making discoveries about comet 3I/ATLAS and sending a mission to the Sun. 📍 Closer to Earth, our Celeste satellites broadcast their first navigation signals in April. esamultimedia.esa.int/multimedia/p...
🛰️Revealing OpSTAR's patch! OpSTAR is our bright new demonstrator mission, aimed at showcasing how optical technologies can reshape the architecture of satellite navigation, enable greater accuracy and strengthen resilience. Can you spot all the hidden elements? www.esa.int/Applications...
🛰️ We're putting the pieces together for Galileo second generation. Here, the electric propulsion system is being lowered onto the satellite platform of the Airbus Defence and Space satellite family. 🔗 www.esa.int/ESA_Multimed... @esa.int @euspa.bsky.social @ec.europa.eu
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. Read about how ESA is strengthening the global geodesy supply chain 👉 www.esa.int/Applications... 📸: UN-GCCE
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. 📅 Save the date: 11.06.2026 🔗 www.youtube.com/watch?v=q2bL... @esa.int @euspa.bsky.social @ec.europa.eu @designdatagmbh.bsky.social
🧭 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 ⬇️
🛰️ 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!
🛰️ 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. www.esa.int/Applications...
Galileo signals reach all the way to the Moon! 🛰️🌙 Last year, a joint ASI and NASA mission determined its position on the Moon using Galileo and GPS satellites and tested Galileo's Emergency Warning Satellite Service on the Moon. 🔗 www.esa.int/Applications... 📸 @firefly-aerospace.bsky.social
🚀 Did you miss our first Celeste launch? Watch the replay! Last Saturday, the first two satellites of our new satellite navigation in-orbit demonstration mission flew into space aboard Rocket Lab’s Electron rocket from the Māhia Launch Complex in New Zealand. www.esa.int/ESA_Multimed...
💫 ABSOLUTELY CELESTIAL! This Saturday, @rocketlabcorp.com took the first two Celeste satellites into orbit. They are alive and well. This is a major step forward in strengthening Europe's ambition for more resilient satellite navigation. www.esa.int/Applications... 📷 Rocket Lab, ESA–D. Ducros
Lift-off! The Electron rocket is blasting in the New Zealand sky. Separation is expected in about an hour. Go Celeste!
🚀 #JoinUsLive this morning for the first Celeste launch! This morning, starting 9:53 CET, join us live for the inaugural launch of ESA’s Celeste LEO-PNT in-orbit demonstration mission, taking place aboard @rocketlabcorp.com’s Electron rocket from New Zealand. www.esa.int/Applications...
🚀 Celeste: The rocket is out! The Electron rocket was rolled out at Rocket Lab’s Māhia Launch Complex. Waiting inside the rocket, the two Celeste spacecraft are ready for their journey to power next-generation satellite navigation technologies from low Earth orbit! www.esa.int/Applications...
🟢 The ESA Celeste mission patch is packed with meaning, highlighting the mission's ambition. Can you find all the elements hidden in the design? 👀 www.esa.int/ESA_Multimed...
🛰️Next time the Celeste satellites see the Sun, they will be in space. The first two Celeste satellites have been placed inside @rocketlabcorp.com ‘s Electron rocket fairing ahead of their planned launch on 24 March. www.esa.int/Applications...
The two Celeste satellites have been integrated on the dispenser of the @rocketlabcorp.com’s Electron rocket. From this point onward, they will travel as single unit through the final steps of launch preparation. Follow the launch campaign here 👉 www.esa.int/Applications...
📏 Is Celeste ‘fit’ for flight? Yes, it is! The team performed a fit check, verifying that the satellites correctly mated with the launcher adapter that will secure them during ascent. www.esa.int/Applications...
🎵 Every good story needs a cool soundtrack! We have put together a playlist that the Celeste mission will (metaphorically) take with it into orbit. Can you connect all the dots? open.spotify.com/playlist/59g...
🚀 Watch the replay of the media briefing we held yesterday ahead of the first launch of the Celeste mission. www.esa.int/ESA_Multimed... @thalesaleniaspace.bsky.social | #gmv
🚀 Celeste is getting ready for flight! Following their arrival in New Zealand, the two Celeste satellites have been undergoing a series of pre‑launch testing and activities at @rocketlabcorp.com’s Māhia Launch Complex. Follow the launch campaign here 👉 www.esa.int/Applications...
Did you know our navigation mission #Celeste is named after Galileo’s daughter, Maria Celeste? In honour of #InternationalWomensDay, as we prepare for Celeste's first launch, we’re reflecting on those who have encouraged us and passing that spark onto someone else.
🥝 Kia ora Celeste! Welcome to New Zealand! The satellites landed in Auckland and were transferred to @rocketlabcorp.com’s Māhia Launch Complex, marking the official start of the launch campaign. Follow for updates 👉 www.esa.int/Applications... @thalesaleniaspace.bsky.social #GMV 📷 Rocket Lab
🛰️ We've found our way to BlueSky 📍 Follow us as we navigate the world of satellite navigation: Galileo, EGNOS, Celeste, NAVISP, FutureNAV and so much more!
