Protecting GNSS and Users – The Ideal APNT

According to the European Commission “…GNSS cannot be the sole means of PNT information … for critical applications requiring continuous availability and fail-safe operations.”

Similar realizations in the United States, United, Kingdom, South Korea and elsewhere have led to a revitalization of efforts to examine Alternative Positioning, Navigation and Timing (APNT) systems that could complement and reinforce our exceptionally valuable, yet vulnerable, GNSS signals.

Securing PNT Workshop Looks at GNSS Back-up Options

With eyes on a future where reliable GNSS back-ups are in place to protect against both accidental or intentional disruptions of GNSS, three organizations represented on Positioning, Navigation and Timing Technical Group (PNTTG) – Innovate UK Knowledge Transfer Network (KTN), Royal Institute of Navigation (RIN) and The General Lighthouse Authorities – hosted a seminar last month to review user needs and the status of two possible RF back-up options to GNSS mentioned in the London Economics report on the economic impact of a GNSS disruption.

Innovate UK / KTN Hosting Technology Seminar: “Securing Positioning, Navigation & Timing”

Innovate UK / KTN (Knowledge Transfer Network) is hosting a technology focused seminar, “Securing Positioning, Navigation & Timing”, June 14 in London. It is designed to explore collaboratively, with users and providers, the need for back-up systems across all sectors and the contribution that may be made by two wide area systems (STL and eLoran) mentioned in the London Economics report.
This meeting is open to all with a professional interest in resilient PNT and is free to attend thanks to the generosity of the event’s sponsors.
