Professor David Last, World Renown PNT Authority, Presumed Lost At Sea


Just before 13:00 GMT yesterday a private plane piloted by former President of the Royal Institute of Navigation, Professor David Last, disappeared from radar and impacted the sea approximately two miles off the coast of Wales.

On-going search and rescue efforts have recovered pieces of wreckage and personal effects.

Professor Last was one of the most respected and well-loved figures in the world-wide positioning, navigation, and timing community.

His loss creates a hole that cannot be filled.

David was a close personal friend of many of the MaRINav team and a long standing champion for improved PNT. David will be sorely missed.

Registration for the MarRINav dissemination workshop, 5th December, BDC London

The MarRINav results dissemination workshop will be held in the KTN Faraday Room in the Business Design Centre, 52 Upper Street, London N1 0QH.
Please proceed directly to the the Faraday Room on the top floor, as the main KTN office will be closed.

Context and Requirements

This report captures and analyses the maritime context for future Critical National Infrastructure (CNI) in the timeframe to 2030.

PNT R&I Technologies and Integration

This report reviews the broad range of options for R&I (Resilience and Integrity) PNT that have been identified in previous studies, analysing the potential contribution of each option.

Maritime Resilience and Integrity of Navigation

MarRINav consortium members Mike Fairbanks and Bob Cockshott FRIN explain the need for a resilient high-integrity PNT solution for maritime navigation in the UK, and outline what is being done to achieve this.

The project aims to explore the vulnerabilities of Global Navigation Satellite Systems (GNSS).

What is MarRINav?

MarRINav (Maritime Resilience and Integrity of Navigation) is a European Space Agency project run in partnership with a consortium of organisations led by NLA International which comprises The General Lighthouse Authority, University of Nottingham, University College London, Taylor Airey, Terrafix, London Economics and the Knowledge Transfer Network (KTN).


What are the project aims?

The project aims to explore the vulnerabilities of Global Navigation Satellite Systems (GNSS) as a Position, Navigation and Timing (PNT) solution in the modern maritime environment.


KTN’s involvement

A key element of this project is engagement with stakeholder groups from industry and academia. KTN is facilitating this stakeholder engagement via meetings and workshops and the report accessible below summarises the findings from the first workshop held in May 2019.

GPS Spoofing: What’s The Risk for Ship Navigation? – Ship Technology

Blog Editor’s Note: An important question ship owners and operators are asking themselves more and more often.

Here is a link to a presentation on this topic RNTF president Dana A. Goward gave last week to a group of shipping industry executives in New York.

Ship Technology


GPS spoofing: what’s the risk for ship navigation?

GPS spoofing – or GNSS spoofing more accurately – is a much-discussed cyber-threat to ship navigation systems. With the potential for paralysed shipping lanes, collisions and even untraceable piracy incidents, what is the current state of play between the shipping industry’s cyber-defences and the malicious actors who aim to cause chaos through GPS spoofing?

The shipping industry has been aware of the threat of GPS spoofing for years, but one incident in 2017 pushed the issue higher up the global news agenda. In June of that year, at least 20 vessels in the Black Sea, in the vicinity of Novorossiysk Commercial Sea Port, reported that their automatic identification system (AIS) traces erroneously showed their position as Gelendzhik Airport, around 32km inland.

The large number of vessels involved and the fact that all of the ships’ tracking systems placed them in the same nonsensical location, led to informed speculation – still unconfirmed officially – that the incident could be attributed to Russian testing of satellite navigation spoofing technology as part of its electronic warfare arsenal.

“My gut feeling is that this is a test of a system which will be used in anger at some other time,” the UK Royal Institute of Navigation’s former president David Last told New Scientist in 2017.

Since then, there have been persistent concerns that the shipping industry may be vulnerable to GPS spoofing, raising the risk of keeping ships at sea longer than necessary to clear the confusion, as occurred in the Black Sea, or even dangerous scenarios such as ship collisions, either with other ships or with land.

Earlier this year, UK-based cyber vulnerability testing firm Pen Test Partners released information from a demonstration at the Infosecurity Europe conference, where the company’s researchers showed how electronic chart systems could be hacked to spoof the size and location of vessels. This, they argued, could cause chaos in a busy shipping lane such as the English Channel.

So what exactly is GPS spoofing, what threat does it pose to shipping, and what action should the industry be taking to reduce the risk?

GPS spoofing: from military to civilian

GPS spoofing could be described more specifically as Global Navigation Satellite System (GNSS) spoofing, as this is the generic term for satellite navigation systems with global coverage, including GPS (US), GLONASS (Russia), BeiDou (China) and Galileo (Europe), all of which are used in the shipping industry. To clarify, this article will use the two terms interchangeably.
