Enhanced GNSS Resilience Against Interferences in Autonomous Navigation with UAV Navigation–Grupo Oesía and Septentrio
As resilient navigation becomes an increasingly critical focus within the UAS industry, UAV Navigation–Grupo Oesía is reinforcing its leadership by collaborating with Septentrio, part of Hexagon, to ensure compatibility with advanced GNSS receivers featuring high-precision RTK (Real Time Kinematic) capabilities combined with AIM+ anti-jamming and anti-spoofing technology. The anti-spoofing resilience is enabled through Galileo OSNMA (Open Service Navigation Message Authentication) service alongside Septentrio’s other proprietary algorithms.
With this collaboration, the UAV Navigation-Grupo Oesía GNC system is now capable of automatically detecting when a Septentrio OSNMA-enabled receiver is connected, seamlessly prioritizing its data within the navigation logic. This behavior highlights the high level of interoperability of the Spanish company’s flight control system, ensuring optimal performance. This cooperation supports UAV Navigation–Grupo Oesía’s ongoing commitment to delivering robust and secure solutions capable of withstanding threats such as GNSS jamming and spoofing. The Spanish company, a recognized expert in Guidance, Navigation, and Control (GNC) solutions for UAS, has a strong track record in contested environment navigation, where its systems have consistently demonstrated the accuracy of their inertial algorithms through real-world operational experience. This expertise led, for example, to the development of the market’s first AI-based visual navigation system, which significantly improved navigation performance and reliability.
“Achieving interoperability with Septentrio’s advanced GNSS modules, equipped with Galileo OSNMA and RTK capabilities, significantly enhances the resilience and precision of our navigation systems.” explains Miguel Ángel de Frutos, Director and CTO at UAV Navigation–Grupo Oesía. “This collaboration underscores our commitment to delivering robust solutions capable of operating reliably in contested and GNSS-denied environments. Septentrio’s expertise in multi-constellation GNSS technology and anti-spoofing measures complements our focus on developing autonomous navigation systems that meet the stringent demands of modern aerial operations” he adds.
For his part, Gustavo López, Market Portfolio Manager at Septentrio, notes: “Working alongside UAV Navigation–Grupo Oesía demonstrates the effectiveness of our AsteRx-m3 Pro GNSS board and the AntaRx-S3 smart antenna in enhancing UAV navigation systems.” He adds: “Our GNSS receivers, featuring advanced anti-jamming and anti-spoofing technologies, provide resilient and accurate positioning even in challenging environments, ensuring mission success in both civilian and defense applications.”.
This interoperability milestone marks another step forward in delivering secure, reliable, and high-precision navigation solutions for unmanned systems operating in GNSS-denied and challenged environments.
UAV Navigation–Grupo Oesía continues to reinforce its position as a technology leader in autonomous navigation, delivering resilient solutions ready to meet the challenges of modern aerial operations.
