NAVISP featured an interview with NAVAC member Olivier Colaitis, who discussed how various applications rely on Positioning, Navigation, and Timing (PNT) systems, and outlined the path toward a future where resilient and trustworthy PNT is achieved by integrating multiple systems.

About the Speaker:

Olivier Colaitis served as Vice President at ASTRIUM and CEO of Telespacio France. Throughout his extensive professional career, Olivier has witnessed the evolution of GNSS and PNT technologies from their early days to their current wide range of applications.

Interview Highlights:

•            PNT is a European success story. GNSS, as its backbone, has rapidly evolved, expanding its application scope from initial uses such as aviation to a broad range of enhanced or new applications that depend on position or time, including micromobility and improved public transportation services.

•            Achieving safe, reliable, and ubiquitous PNT depends on combining different space-based and terrestrial systems to deliver trustworthy positioning everywhere—resilient to jamming, spoofing, or system outages.

•            Advances in resilience, hybridization, intelligence, and security will pave the way for an integrated, layered approach to PNT, enabling safe support for many more diverse user applications in the future.
