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.

Army Launches 5-Year PNT Technology R&D Program

The Army is kicking off a wide-ranging, five-year research effort to develop new position, navigation and timing (PNT) technologies for battlefield use.

The goal is to overcome technical barriers in a wide range of areas and military officials are offering to fund multiple, and even multi-phase, cost-plus-fixed-fee (CPFF) efforts to do that. The work may range from studies and analysis to development work that results in the production of a prototype-style deliverable or breadboard and/or a demonstration.

Navigating in Space

Figures 1 & 2

Spacecraft in low Earth orbit (LEO), at altitudes below 3,000 kilometers, remain within the main Global Positioning System (GPS) signals’ Earth coverage. Spacecraft employing GPS at these altitudes enjoy signal availability and navigation and timing performance emulating that of terrestrial users.

GLONASS and PNT in Russia

The legal and regulatory framework of the Russian Federation covers not only the GLONASS system, but the country’s overall positioning, navigation and timing (PNT) system as well.

The term PNT is a synonym for navigation activities as defined in the Federal Law on Navigation Activities. The PNT system in the Russian Federation is defined as the combination of administrative and technical means that provide spatial and time data to all user groups, with GLONASS as a key element.
