The declaration of the EGNOS Safety of Life service in March 2011 marked the moment when satellite navigation became certified for safety-critical aviation operations in Europe, allowing pilots to rely on EGNOS for precision approaches and improved situational awareness during landing. Fifteen years later, the service continues to play a critical role in improving safety, accessibility and efficiency in European airspace, demonstrating the long-term value of satellite-based navigation for safety-critical transport applications.
The European Geostationary Navigation Overlay Service (EGNOS) enhances positioning signals from global navigation satellite systems, primarily GPS, by improving their accuracy, reliability and integrity. Through a network of ground stations and geostationary satellites, the system broadcasts corrections and integrity information that enable users to rely on satellite navigation even in safety-critical situations.
EGNOS is a key component of the European Union’s satellite navigation infrastructure and an integral part of the European Union Space Programme. The system is owned by the European Union, with the European Union Agency for the Space Programme (EUSPA) responsible for the overall programme management and development of the service.
As the certified EGNOS service provider, European Satellite Services Provider (ESSP) ensures the day-to-day operational and service provision of EGNOS, guaranteeing the response to user needs and the levels of accuracy, integrity and availability required for safe and reliable navigation.
Together, these partners have been contributing to the continuous development and delivery of EGNOS, supporting safer skies and enabling a growing ecosystem of satellite-based applications across Europe.
Enabling safer and more accessible approaches
The primary objective of the EGNOS SoL service is to support civil aviation operations down to Localizer Performance with Vertical Guidance (LPV) minima, enabling aircraft to conduct approaches with both lateral and vertical guidance using satellite navigation.
This capability significantly improves accessibility to airports, particularly those without costly ground-based navigation infrastructure such as Instrument Landing Systems (ILS). By enabling LPV approaches with decision heights as low as 200 feet, EGNOS helps enhance safety while expanding operational flexibility for airports and airlines across Europe.
Since its launch, the EGNOS Safety of Life service has enabled more than a thousand satellite-based approach procedures across European airports, allowing pilots to land safely even in low-visibility conditions.
From system deployment to operational service
The launch of the SoL service was built upon earlier milestones in the EGNOS programme.
• 2005: Initial EGNOS signal transmissions and early operational capabilities.
• 2009: The EGNOS Open Service became operational, providing improved positioning accuracy for mass-market users.
• 2011: The Safety of Life service was officially declared operational for aviation.
• 2015: The LPV-200 (Localiser Performance with Vertical guidance) delivering lateral and angular vertical guidance until an aircraft is 200 feet above the runway is available.
Together, these services established EGNOS as a cornerstone of Europe’s satellite navigation ecosystem and an important complement to global navigation systems.
Continuous evolution of performance and coverage
EGNOS has continuously evolved to meet the growing needs of the users. System upgrades, improved algorithms and infrastructure enhancements have progressively strengthened service performance.
The expansion of LPV procedures across Europe demonstrates the growing maturity of satellite-based navigation and the confidence that aviation stakeholders place in the system.
In addition to aviation, the EGNOS concept has opened opportunities for safety-critical navigation applications in maritime, demonstrating the system’s potential for multi-modal mobility.
A milestone for European aviation
Fifteen years after its launch, the EGNOS Safety of Life service stands as a key pillar of Europe’s satellite navigation infrastructure. By enabling safer landings, expanding airport accessibility and supporting innovation in navigation technologies, the service continues to demonstrate the tangible benefits of European Union space programme.
As the system evolves toward the next generation of satellite-based augmentation, EGNOS remains committed to its core mission: providing reliable navigation services where accuracy, integrity and safety are essential.
Closing
What started as a pioneering service to enhance aviation safety has grown into a cornerstone of Europe’s satellite navigation ecosystem. Fifteen years on, EGNOS continues to deliver the accuracy and reliability that users rely on, helping to shape a future where satellite navigation supports safer skies, smarter transport and new innovations across Europe.
As the system evolves toward its next generation and closer integration with the Galileo satellite navigation system, EGNOS will continue to play a key role in supporting the future of precise and trustworthy satellite navigation.
