As reliance on GNSS continues to grow across defense operations, so does exposure to disruption. Jamming, spoofing and interference are persistent, evolving and increasingly challenging to detect in contested environments.
The challenge extends beyond signal disruption. Hidden failure modes, systemic dependencies and fragmented ownership are creating new risks across mission-critical systems, with downstream impacts on aviation, maritime, telecom, finance and energy infrastructure.
In this webinar, industry experts will explore how the PNT challenge has changed and what it means for building resilient, trusted systems in GNSS-denied and degraded environments.
Through a moderated discussion format, speakers will examine how defense organizations and supporting industries can move beyond a GNSS-first mindset toward multi-layered PNT architectures, improved situational awareness and coordinated strategies for detection, response and recovery.
What You’ll Learn
- How the PNT threat landscape is evolving in contested and denied environments
- Why GNSS-only approaches are no longer sufficient for mission assurance
- What resilient, multi-layer PNT architectures look like in defense applications
- How to improve detection, response and recovery under operational constraints
- Key considerations for implementing and scaling resilient PNT systems
1. The PNT challenge has changed: Looking beyond jamming and spoofing
Andy Proctor – RethinkPNT / Royal Institute of Navigation
