Editor's Note: Every new article on maritime spoofing provides a bit more information on this unfolding story. This piece has a great first-person account from the vessel master who reported the June Black Sea incident. Wired.co.uk Hacking When a tanker vanishes, all...

Editor's Notes: Two recent press items below of interest.   The first is that the US Navy is not done examining the possible impacts of cyber (we hope to include possible GPS jamming and spoofing) on recent collisions. While they have said no evidence was found of a...

Editor's Note: The  item below on June's GPS spoofing is outstanding. It was published by the government-owned Norwegian Public Broadcaster, NRK. The article includes video of: Spoofing of the June incident in the Black Sea (video created by the Norwegian Defense...

Editor's Note: China certainly had the means, motive, and opportunity to harass this dissident. Yet people in the US should be safe from attack by foreign governments. It will be interesting to see if the FBI will release their findings, and, if it was a Chinese...

In technical report entitled "GPS Vulnerability" released Friday, the Alliance for Telecommunications Industry Standards (ATIS) renewed its call for an eLoran system to support telecom and other critical infrastructure in the United States. As part of its...

Editor's Note:  The European Commission says they have identified over 140,000 unique electronic signatures for GPS jammers in Europe as a part of random sampling studies. We wonder that there are not more of these incidents being made public. Also that there is so...

The US Maritime Administration (MARAD) issued an alert concerning reports of GPS spoofing in the Black Sea on the 22nd of June. At the time they characterized the report as "unsubstantiated." On the first of this month, MARAD issued Maritime Advisory 2017-006 :...

Editor's Note: Bob Poole is a respected authority on air traffic control policy issues. His widely read and respected newsletter offers thoughtful commentary on policy and operational issues. The most recent edition encourages efforts in the Congress to provide a...

Editor's Note: It is great to see some investors understand the need for an eLoran system to enable shipping to be safer and more efficient. Would be good if we had empowered people with his vision in the right places in government. Brian Ladin of Delos Shipping...

Editor's Note: This article responds to the question from mariners and others in the industry - 'What's going on? We hear about new Chinese satellites, European satellites, and other projects all the time, but none of it seems to be making a splash.'  Global eNav -...

Editor's Note: This piece by three professors from the US Naval War College is comprehensive and disturbing. Very much worth the read for anyone remotely interested in maritime or cybersecurity issues.  Our thanks to Mr. Richard Hiscock and the folks at...

Editor's Note: The below article from Pravda.ru says it was sparked by US and British media reports "...that Russia tested an unknown cyber weapon in the Black Sea in June." It goes on to say "Western publications are full of reports about Russia's new cyber weapon...

Editor's Note: North Korea has repeatedly trialed and demonstrated its GPS jamming capability on South Korea. There are some who have argued that GPS disruption cyberattacks could be very difficult to locate, terminate, and attributed.  Easily transported and...

Editor's Note: Our experience navigating at sea and in the air has shown that human error is by far the most likely culprit in mishaps of nearly every kind. That's why our response to suggestions of jamming, spoofing or other cyberattack as a factor in the USS McCain...

Editor's note: Several interesting nuggets in this article. First, the overt justification for eLoran in this instance is an external threat and its impact on maritime - though aviation and telecommunications have been similarly impacted by the North's jamming.  As we...

Editor's Note: Lots of press and speculation on this issue. We re-post this one here as it has something we have not seen elsewhere - a report that a retired Australian Naval Intelligence officer suspected a cyber attack/GPS spoofing to be a factor in June's USS...

National Defense VIEWPOINT: GPS Spoofing Incident Points to Fragility of Navigation Satellites 8/22/2017 By Dana Goward A relatively innocuous safety alert from the U.S. Maritime Administration last month belied the dramatic impact upon vessel navigation in the area....

There are many possible causes for the recent tragic collisions of USS Fitzgerald and USS McCain with merchant vessels. Several media outlets have speculated that they could have been the result of cyber attacks against the Navy vessels.  See news.com.au  and msn.com,...

Editor's Note: EUVs, TECs, TIDs and gravity waves - NASA thinks GPS service in the US will be "OK"  during the eclipse next week, but they aren't entirely sure.  Another reminder that the behavior of highly complex systems with ultra-fine tolerances under non-standard...

Editor's Note:  Kudos to Matt Leonard for beginning this article by identifying purposeful GPS disruption as a cyber-attack. Despite the disruption of communication pathways, impact on end-use devices, and the potential for inserting false information into data bases...

Editor's Note: The Black Sea incident in June is almost inexplicable.  The theory put forth below is plausible as to the mechanics of  what happened, but one wonders why the Russian military would reveal its capability is such a haphazard manner. As a warning of what...

The European Commission has reported detecting over 140,000 unique electronic signatures of GPS/GNSS jammers during the limited sampling it has done on the continent. While there are undoubtedly an equal or larger number of jammers operating in the United States,...

Editor's Note: Good article from "The Diplomat." About two-thirds the way through the reporter makes the point that the issue more important than navigation for navies (and everyone else) is the reliance on GPS for network timing. He clearly did his homework....

Editor's Note: A couple things of note about this very short item posted last week. First, it is published by "GPS World."  It shows wide recognition in the satnav community that space-based sources for positioning, navigation and timing should be complemented with...

Reuters Article carried by the New York Times, Wall Street Journal and others. Editor's Note: A good article from Jonathan Saul below.  For those new to the topic a couple points of clarification may be warranted: The focus of this article is maritime, though the most...

Editor's Note: The below article from "Inside GNSS is a good follow-on to our June post about the UK government report on the economic impact of GNSS disruption. The report's conclusion was that both eLoran and the low earth orbit satellite system Satelles could serve...

  "Inside GNSS" reported today that the House Defense Appropriations Act for 2018 provides $10M for the GPS complementary and back up system proof of concept called for in the 2018 National Defense Authorization Act (NDAA). This was as a result of an amendment...

Criminals stealing high value cargo, delivery drivers hiding from their employers and those hiding illicit affairs from their spouses aren't the only ones who regularly jam GPS reception. "Electronic countermeasures" are employed by a wide variety of security...

Editor's Note: Cameras, radar, and "sensors" will complement GPS in the navigation suite. We have asked for more detailed information from our friends at Kongsberg. It seems to us that having resilient navigation would be important. Wall Street Journal Norway Takes...

Editor's Note: Last week the US House of Representatives passed H.R. 2825 - the Department of Homeland Security (DHS) Act of 2017. Part of that bill included provisions for the US Coast Guard, a DHS agency, which require establishment of an eLoran system to provide a...
