Keeping the world connected through satellite navigation. Advancing positioning, navigation and timing in Europe with innovative technologies and resilient systems. Part of the European Space Agency @esa.int family.
@navigation.esa.int🌕📍🕰️ Introducing NovaMoon: ESA's mission to improve positioning, navigation and timing (PNT) services on the Moon. NovaMoon will help rovers, landers and astronauts navigate on the Moon like cars, planes and pedestrians navigate on Earth.

@navigation.esa.intHow do you turn satellite navigation into a story? In our interview with the director of “Finding Our Way: Inside the Galileo Project”, we asked this and more.

@navigation.esa.int💅Kinda chic to take part in Jammertest, the world's largest open-air satellite navigation interference campaign, to enhance Europe's resilience against jamming and spoofing.
@navigation.esa.int🤝 Galileo starts with people. “Finding Our Way: Inside the Galileo Project” brings you into the teams who built Galileo, the system that guides us all.

@navigation.esa.int30 years ago, Europe set out to build an independent global navigation system. “Finding Our Way: Inside the Galileo Project” goes behind the signal that guides us all.

@navigation.esa.int🤔What is Jammertest? Every September, the airwaves of the Arctic island of Andøya become some of the most heavily attacked in the world. Norwegian authorities launch jamming and spoofing attacks for participants to test satellite navigation tech, identify weaknesses and develop stronger solutions.
@navigation.esa.int⚠📶Jammertest pumped up the jam in Norway, and @esa.int was there. A regular Jammertest participant since 2023, ESA brought its largest testing portfolio yet to this year's event. Read more about it 👇

@navigation.esa.intThe Galileo programme is managed by the European Commission under the EU Space programme, with ESA leading its design, development and qualification and @euspa.bsky.social as the system's service provider.
@navigation.esa.int@esa.int and the @ec.europa.eu are joining forces with Museo Galileo on a new exhibition to explore the fascinating links between Galileo Galilei and the European satellite navigation system bearing his name.
Read more about the exhibition, set to open in December 2027 👇
@navigation.esa.int💪 Galileo, EGNOS, Celeste, and technologies developed through Horizon Europe and NAVISP are becoming more resilient every year, thanks in no small part to the unique testing environment that Jammertest provides. 📸: ESA/JensenMedia AS
@navigation.esa.intEvery year, Norwegian authorities create realistic jamming and spoofing scenarios that allow participants to test how their technology performs under pressure. Jammertest is an invaluable resource for the satellite navigation community, including the European Space Agency.
@navigation.esa.int🗺️ 📍 We’ve come to trust maps without question. But maps can lie. Over the past week, we’ve watched ourselves disappear from the map, only to reappear out at sea. In reality, we never left Andøya, a Norwegian island that hosts the world's largest open campaign for GNSS resilience: Jammertest.
@navigation.esa.intThe upcoming service, in combination with the already available Open Service Navigation Message Authentication (OSNMA), will allow receivers to detect and reject a wide range of spoofing attacks. OSNMA and SAS will be free to access and available worldwide.

@navigation.esa.int🆕 Galileo achieves first position fix using encrypted Signal Authentication Service (SAS) signals.
At #Jammertest, test signals from five operational satellites enabled a receiver to establish its location under spoofing conditions, unlocking a new level of protection against interference.
@navigation.esa.intTo make sure we can trust the blue dot, ESA continuously works to strengthen the resilience of European navigation systems. And that is also why ESA is taking part in Jammertest, helping develop systems and technologies that are even more robust. 🔵 📸: ESA/JensenMedia AS
@navigation.esa.int🔵 In a meaconing attack, instead of fake signals, real signals from a nearby location are rebroadcast. Again, there is a blue dot but not where it is supposed to be.
@navigation.esa.int🔵 With spoofing, the blue dot is still there, but it is in the wrong place. False signals trick the receiver into calculating an incorrect location.
@navigation.esa.int🔵 Jamming occurs when a powerful signal floods a receiver, drowning out the real satellite signal. The receiver can't calculate a position, so the blue dot turns grey and disappears.
@navigation.esa.intEveryday, countless people rely on the little blue dot 🔵 in their navigation app to get them safely to their destination. But what happens when that dot disappears or leads us astray? Satellite navigation can be disrupted in several ways ⬇️
