💅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.

🤔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.

🗺️ 📍 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.

ESA Navigation
@navigation.esa.int

Every 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.

ESA Navigation
@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

🆕 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.

ESA Navigation
@navigation.esa.int

The 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. Read more: lnkd.in/e9QBAfqJ

Everyday, 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 ⬇️

🔵 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.

ESA Navigation
@navigation.esa.int

To 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

ESA Navigation
@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.

Greetings from the Arctic! After covering thousands of kilometres, @esa.int's team and its office on wheels have arrived in Andøya, Norway. This remote island is about to become one of the most heavily attacked GNSS environments in the world, but in a controlled way and for a good reason.

ESA Navigation
@navigation.esa.int

Over the coming days, Norwegian authorities will broadcast real satellite navigation interference for participants to learn how their equipment (on vehicles, drones, aircraft, helicopters and vessels) responds, and ultimately help develop more resilient navigation systems and technologies.

ESA Navigation
@navigation.esa.int

ESA returns to #Jammertest each year with new technologies and system features to put to the test. The results gathered in Norway feed directly into the work that is carried year-round at the ESTEC navigation laboratory and beyond.

Last night we brought together astronauts, ministers, industry leaders and space enthusiasts to celebrate the imagination, innovation and cooperation that define Europe's journey in space. From Earth orbit to deep space, we were reminded that today's ambitions become tomorrow's achievements.

⌛The countdown is on! ESA’s navigation lab on wheels is setting off for Andøya, Norway, home to the world’s largest satellite navigation resilience test where hundreds of interference scenarios challenge receivers tracking satellite navigation systems. Stay tuned for updates from the field!

⛵ 🛰️🏛️ What would have happened if Odysseus had Galileo when he set sail for Ithaca after the Trojan War? A ten-year journey completed in a matter of weeks…but then we wouldn't have The Odyssey. How does modern satellite navigation relate to Odysseus’s journey? Find out below⬇️

🌊⛵ Odysseus is shipwrecked more than once on his journey home, left to the mercy of the sea (and Poseidon). With an emergency beacon, he could have tapped into Galileo’s Search and Rescue Service with Galileo satellites picking up his distress signal and relaying it to local rescue teams.

🧜‍♀️⛵ The Sirens attempt to steer Odysseus off course with their alluring call, similar to the way spoofed satellite navigation signals lead receivers astray. Galileo’s OSNMA helps mitigate the risk of spoofing by helping the receiver determine whether the signal truly came from the Galileo system.

🕰️⛵ Odysseus spends a year on Circe’s island after freeing his crew from their transformation into pigs. Galileo’s precise timing, with atomic clocks accurate at nanosecond levels, could have helped him keep track of time. Galileo’s timing is so precise, it’s used as a standard for Europe’s time.
