    "description": "Since 2017, our team at DLR and partners across Europe have been working on an alternative to satellite navigation: **R-Mode**, a backup system based on terrestrial transmitters. Our main testbed spans the Baltic Sea — a region now infamous for GNSS jamming and spoofing.\r\n\r\nWe’ll start by showing what GNSS interference actually means in practice: aircraft losing navigation data, ships switching to manual control, and entire regions facing timing outages — such as the recent disruption of telecommunications in Gdańsk during Easter 2025.\r\n\r\nThen we’ll take you behind the scenes of building R-Mode: designing signals that can coexist with legacy systems, installing transmitters along the coast, and testing shipborne receivers in rough conditions. We’ll share personal moments — like the first time we received a stable position fix in the middle of the Baltic.\r\n\r\nFinally, we’ll talk about perception and politics: how a “research curiosity” became a critical infrastructure project, why ESA now wants to build a *satellite* backup (with the same vulnerabilities), and how it feels when your civilian open-source navigation system suddenly becomes strategically relevant.",
