Resource Portal for Resilient Positioning, Navigation and Timing
This page is designed to provide easy-access to resources and information for protecting and assuring position and time.
The economic impact on the UK of a disruption to Global Navigation Satellite Systems (published 6 June 17)
Satellite-derived time and position: Blackett review exploring the dependency of the UK on global navigation satellite systems (published 30 Jan 2018)
GPS / global navigation satellite system vulnerabilities: FAQ (published N/A (live web page))
The evolution of global navigation satellite system spoofing – technology evolution / revolution (published December 2018)
Reliance and vulnerability of Global Navigation Satellite Systems – report by the Royal Academy of Engineering. The study includes consequences of failure or degradation of the GPS service or the associated ground based systems (published March 2011)
Extreme space weather: impacts on engineered systems and infrastructure – report by the Royal Academy of Engineering. The study includes a chapter (#10, pages 45-47) specifically covering impacts on satellite navigation receivers, systems and applications (published February 2013).
LinkedIN group on GNSS vulnerabilities
Resilient Navigation and Timing Foundation - this not-for-profit organisation's mission is to promote resilient navigation and timing worldwide. A range of resources is accessible from the Foundation's web page.
An excellent summary of how to assess and make business decisions about technology and information risks. From the UK National Cyber Security Centre (published September 2016).
White paper on risk assessment and mitigation approaches from the Resilient Navigation and Timing Foundation. Although the title is US centric, the model presented applies universally. Recommended reading if you are looking for a practical tool to rationalise and understand the risks.
We are hoping to add suitable content here in the near future. Please let us know if you are aware of useful links.
The SENTINEL Report - link on this page. Some pioneering industrial research conducted into the threat posed by jamming and interference to satellite navigation (published April 2014).
STRIKE3 - Monitor, Detect, Characterise, Standardize, Mitigate and Protect – an EU-funded project to develop and validate new international standards for the monitoring, reporting and testing of GNSS threats.

US Coastguard Problem Reports – a summary of events reported, together with a reviewed assessment of the likely cause of the disruption.https://www.navcen.uscg.gov/?Do=GPSReportStatus
UK Ofcom report with notification of planned Ministry of Defence military system GPS testing.
Responsible Use of GPS for Critical Infrastructure (published: 6 Dec 17)
Link to gps.gov, the official US government information site for GPS. Readers may wish to focus in particular on information on the currently ongoing issues about adjacent band compatibility (ABC) and the (often excellent) presentations from the US Positioning, Navigation and Timing Advisory Board (PNTAB) and Civil GPS Interface Committee (CGSIC) meetings.
Multi-level Resiliency Model Concept (published 2018)
US National Risk Management Center Briefing to US Positioning, Navigation and Timing Advisory Board (December 2018)
General Guidelines and Standards
Ofcom light licencing regime to authorise the use of satellite navigation repeaters in the UK.
Radio Equipment Directive – covers the efficient use of radio spectrum
A useful blog from Spirent Communications explains how this applies to GPS and satellite navigation equipment: https://www.spirent.com/blogs/positioning/2017/february/gps-device-manufacturers-ready-for-red
Use of On-Train Satellite Positioning Technology Based Locator for Railway Applications – provides guidance on good practices in support of applications requiring train position, speed and time (PVT).
EC-RRG Resilience Guidelines for Providers of Critical National Telecommunications Infrastructure – best practice guideline for establishing and maintaining resilience. Although not specific to navigation or timing resilience, included here as the principles are felt to be of interest across multiple domains.
Maritime Standards for Positioning, Navigation and Timing
Global Positioning System (GPS) receiver equipment – defines the high-level receiver performance requirements to enable the use of GPS on Safety-of-life-at-sea (SOLAS) vessels.
