Blog Editor's note: It is not clear from the report below if the Russians were jamming GPS and also jamming cell phone frequencies, or if, as a by product of GPS jamming, cell phone networks were also impacted. - Networks of all kinds  rely on GPS timing for...

Two weeks ago we posted a Norwegian press report about Russia jamming GPS signals in northern Norway. Here is the translated official interference measurement report from the Norwegian Communications Authority. Technologists will enjoy the screen shots from various...

Blog Editor's Note: This is not a new issue to our regular readers, but it is always good to periodically highlight this issue. Not all threats are from bad actors. Accidents, Mother Nature and the lack of resilience in our major systems are equally or more important...

Blog Editor's Note:  Here is another good overview article. The reporter from QZ.com, which focuses on the finance and banking industry, became interested in the topic after watching the video of the recent National Space Council (see yesterday's blog post).  Tim...

Vice President Pence chaired the new National Space Council's first meeting on the 5th of October. The third panel discussed the importance of space assets and their security. Particularly noteworthy was this comment by Dr. Michael Griffin, former NASA Administrator:...

"How vulnerable is GPS/GNSS in defense/security/critical government applications (that is M-code or similar) to disruption by jamming whether intentional or unintentional?" 91% of the respondents in a "GPS World poll answered with "Somewhat," "Very," or "Extremely"...

ATM transactions, market trades, network management... these and a host of other dependencies mean that, without good time references, financial services are out of business. The NYSE alone sees hundreds of trades a second and regulators are continually tightening the...

Editor's Note: The President reestablished the National Space Council in June and it recently held its first meeting.  While furthering America's efforts in space were discussed, the importance and vulnerability of space assets were also reviewed at some length.  See...

Blog Editor's Note: The cellular network's vulnerability to GPS disruption has been well documented and was recently the subject of a report by ATIS.  This is the first report we have seen about the impacts to the smart phones themselves. Inside GNSS An Accidental...

Editor's Note: This statement in a US Army Handbook published in December 2016 came to our attention when it was cited and a link was provided in an Norwegian Channel 2 report about Russia jamming GPS (but not GLONASS) signals in northern Norway for a week. The...

Editor's Notes: Experts have observed that the jamming described below was very sophisticated in that it jammed only the US GPS satellite navigation system. The Russian GLONASS satellite navigation system uses a frequency very close to that of GPS but was unaffected....

Editor's note: The following is from Bob Poole's Excellent ATC Reform News. It is a good reminder of the many concealed costs GPS vulnerability imposes across all transportation modes and infrastructures. The article discusses a recent GAO report on the FAA's Next...

Editor's Note: Dr. Per Enge is a noted authority on electronic navigation and fellow member of the National PNT Advisory Board. If you were at ION in Portland last week, you may have attended his tutorial about resilient PNT. Congratulations, Per, on this new...

Editor's Note: This post from the US Coast Guard is a good reminder about safe navigation practices. The master involved did very well. He was also fortunate that he was well off shore in open water and his GPS was off by 25 miles. If he had been in restricted waters...

SAE, the world's largest standards setting organization, recently concluded a work group meeting on standards for complementary PNT to protect critical infrastructure and automated vehicles of all kinds (air, land, sea).  The US government has twice announced that the...

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: 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....
