Safran - Navigation & Timing

🛰️ More satellites. More signals. A more complex RF environment. As LEO constellations continue to expand, the way we think about radio-frequency interference is evolving too. This interesting article from the International Telecommunication Union looks ahead to WRC-27 and highlights a growing challenge: moving beyond interference from individual satellite systems to consider the aggregate impact of multiple non-GSO constellations. While the article focuses on radio astronomy, the broader topic resonates strongly with the PNT community. As satellite-based services multiply, understanding increasingly complex RF environments - and ensuring that systems can operate reliably within them - is becoming ever more important. For PNT, this reinforces the importance of realistic simulation, testing and resilient navigation technologies, particularly as LEO becomes an increasingly important part of the navigation landscape. An interesting read on how our shared spectrum environment is evolving. 👇 https://hubs.li/Q04y6k1J0 #PNT #LEO #GNSS #ResilientPNT #SatelliteNavigation #Spectrum #WRC27 #Safran-Space

What does resilient PNT really mean for autonomous platforms? As GNSS jamming, spoofing and signal denial become part of the operational environment, navigation can no longer rely on GNSS alone. In this new Q&A, Jean-François Jourdas, VP Programs – GNSS, Simulation & Navwar, explores how tightly coupled GNSS, inertial navigation and advanced sensor fusion can help deliver trusted PNT - and how collaborative PNT, LEO-PNT, alternative navigation sources and AI could shape the next generation of resilient navigation. 👉 Read the full Q&A : https://hubs.li/Q04yxxxW0 #ResilientPNT #Navigation #AutonomousSystems #GNSS #NavWar

✈️ On This Day in Navigation History | September 24, 1929 What if a pilot could fly without seeing outside the cockpit? On September 24, 1929, aviation pioneer Jimmy Doolittle demonstrated that it was possible. Flying with his cockpit view obscured, Doolittle took off, flew a set course and landed relying on instruments and radio navigation rather than external visual references. His historic “blind flight” helped demonstrate the potential of instrument flying - a major step toward safer, more reliable all-weather aviation. Nearly a century later, the technologies have transformed: from early gyroscopic instruments and radio aids to GNSS, inertial navigation and resilient PNT. But the objective remains remarkably similar: knowing precisely where you are, where you're going and how to get there - whatever the conditions.

🌊 How can we accurately observe what is happening up to 1,500 meters beneath the Arctic ice? Tara Polar Station has begun its overwintering period in the heart of the Arctic Ocean. For nine months, scientists will explore, document and deepen our understanding of this rapidly changing polar ocean. Among the instruments on board, acoustic sounders will be used to assess the biomass present in the water column beneath the ice, as well as to measure the speed and direction of ocean currents down to depths of 1,500 meters. But this raises a major challenge: how can the reliability of these measurements be ensured when the station is constantly moving? Roll, pitch and changes in heading can affect the accuracy of observations, particularly at greater depths. To correctly interpret the data collected, it is therefore essential to know the station’s precise orientation at the exact moment each measurement is taken. This is where the inertial navigation system comes into play. 🎥 Thomas Linkowski, Oceanographic Engineer at Fondation Tara Océan, explains what the sounders can reveal beneath the Arctic ice and the challenges involved in obtaining reliable scientific data. https://hubs.li/Q04xHldM0 --------------------------------------------------------------------------------- 🌊 Comment observer avec précision ce qui se passe jusqu’à 1 500 mètres sous la banquise ? Tara Polar Station a démarré son hivernage au cœur de l’océan Arctique. Pendant 9 mois, les scientifiques vont explorer, documenter et mieux comprendre cet océan polaire en pleine transformation. Parmi les instruments embarqués, des sondeurs permettront d’évaluer la biomasse présente dans la colonne d’eau sous la glace, mais aussi de mesurer la vitesse et la direction des courants océaniques, jusqu’à 1 500 mètres de profondeur. Mais un défi majeur se pose : comment garantir la fiabilité de ces mesures alors que la station est constamment en mouvement ? Roulis, tangage et changements de cap peuvent en effet affecter la précision des observations, notamment à grande profondeur. Pour interpréter correctement les données recueillies, il est donc essentiel de connaître avec précision l’orientation de la station au moment de chaque mesure. C’est là que la centrale inertielle entre en jeu. 🎥 Thomas Linkowski, Ingénieur Océanographe à la Fondation TARA Océan, nous explique ce que permettent d’observer les sondeurs sous la banquise et les défis à relever pour obtenir des données scientifiques fiables. https://hubs.li/Q04xHldM0 #TaraPolarStation #Arctic #OceanScience #Navigation #PNT

🤝 Advancing GNSS resilience together at ION GNSS+! We are pleased to highlight a new collaboration between Safran Electronics & Defense and Emitech Group, bringing together complementary expertise to advance GNSS resilience testing capabilities in Europe. Together, we are combining our expertise in advanced GNSS simulation with Emitech’s state-of-the-art anechoic testing facilities to provide a comprehensive environment for testing and validating resilient PNT technologies. The collaboration will enable testing of critical anti-jamming and anti-spoofing technologies, including CRPA-based solutions, in controlled and realistic RF environments. By bringing together the expertise of two European companies, this initiative also contributes to strengthening sovereign testing capabilities for resilient PNT in Europe. 📍 At ION GNSS+?

🛰️ Shaping the Future of LEO PNT While we’re at ION GNSS+, it’s a great opportunity to highlight the initiatives we are pursuing at Safran around Low Earth Orbit (LEO) and the role these new architectures can play alongside existing GNSS. From our work and collaboration with players such as Xona Space Systems, to initiatives involving Trimble and StarNav, we are exploring how LEO-based PNT can bring new levels of resilience, availability and performance - particularly in environments where traditional GNSS faces its limits. These collaborations bring together complementary expertise across the PNT ecosystem and help us explore how new LEO signals and technologies can translate into robust, real-world navigation solutions. 🚀 The future of PNT will not rely on a single technology or constellation. It will come from combining complementary signals, sensors and infrastructures into solutions that are more resilient and trusted by design. ION GNSS+ is exactly where these conversations belong: bringing together the people and technologies shaping the next generation of navigation. 👉 Learn more about our LEO initiatives : https://hubs.li/Q04xHkG50 #IONGNSS #LEO #PNT #GNSS #ResilientPNT #Navigation #Innovation #Safran-Space

❄️ Tara Polar Station is now in the ice. The scientific adventure begins. After almost two months at sea, Tara Polar Station has reached its targeted ice floe in the Central Arctic Ocean. The station is now trapped in the ice, marking the beginning of the Tara Polaris I scientific drift. 🌊🧊 Over the coming months, the crew will carry out an ambitious scientific programme in one of the most extreme environments on Earth. And PNT (Positioning, Navigation and Timing) technology is onboard. Our inertial navigation system will contribute to providing precise motion and positioning information to support the scientific instruments operating throughout the expedition. In such an isolated and demanding environment, collecting data is only part of the challenge. Knowing how reliable that data is matters just as much. 📅 Stay tuned at the end of September: we’ll take you onboard Tara Polar Station to explain how Safran technology is helping support sonar data reliability and quality during this extraordinary Arctic mission. Congratulations to the Fondation Tara Océan teams and all the scientific partners as this new chapter begins! #TaraPolaris #Arctic #OceanScience #Navigation #InertialNavigation #DataReliability
