Friday the US Department of Homeland Security published a list of 22 recommendations for installation, selection and use of GPS receivers to minimize opportunities for jamming and spoofing.  Among them the document includes: Installation of decoy antennae to...

Editor's Note: This looks like an interesting event at the New York Stock Exchange.  We are going to attend. A similar event was hosted there last year that included a demonstration using an eLoran signal for a timing reference.  DG Time and Money Workshop Agenda...

Editor's Note: The following excellent article by Dee Ann Divis points out that the US Congress remains very much int the lead for GPS/PNT policy in the United States. Virtually every high level issue associated with GPS is addressed in the bill. In addition to...

In a Request for Information posted on the 20th of December the Department of Homeland Security's Science and Technology Directorate is seeking partners in a Limited Purpose Cooperative Research and Development Agreement (CRADA). "DHS S&T is seeking to evaluate...

Editor's Note: Dr. Gene McCall makes several excellent points in the below article about the need to focus on an architecture that will ensure delivery of PNT services.  He very much reinforces our Protect, Toughen and Augment message. Dr. McCall also...

Graphic from AFCEA Editor's Note: The author of this article starts with "Safeguarding the electromagnetic spectrum is critical to success throughout the battlespace, but the ethos and resources needed to secure and defend this vital medium are lacking." What is true...

The cumulative effects of daily low power jamming by thousands of criminals and privacy seekers, and the threat of high power jamming by terrorist and other nations, pose the greatest GPS-related dangers to the United States, according to an RNT Foundation white paper...

Blog Editor's Note: Another excellent article below by Dee Ann Divis. One additional note  - the federal register notice focuses on timing, which has always been the first phase of the effort for a complimentary and backup system for GPS. It also says that the...

Editor's Note:  The below is yet another excellent article by award-winning journalist Dee Ann Divis looking at how specific lawmakers and the new administration may view PNT issues and act to protect our least visible and most vulnerable infrastructure. For anyone...

Blog editor's note: Cyber-security officials and experts have always seemed resistant to the idea that GPS jamming and spoofing were cyber problems. This has never made sense to us. Disrupting GPS and other PNT can disable end use devices, degrade or disable networks,...

The US Department of Transportation is seeking "...one or more PNT technologies to back up signals from GPS and to ensure resiliency of PNT for U.S. critical infrastructure operations."  The Request For Information (RFI)  was published in the Federal Register today....

Ever since GPS became popular enough that receiver antennas began sprouting up in the same general area they have been interfering with each other. A brand new case study from Chronos Technology shows how two GPS antenna can be 20m (60ft) apart and still cause...

"Everybody talks about the weather, but nobody ever does anything."*   So far, it has been the same with GPS/GNSS/PNT vunlerability and the need for a complementary and back up system. Late last month "GPS World" published an item about two workshops on the...

Concerned about the vulnerability of GPS to disruption from a myriad of sources, the US Naval Academy, US Coast Guard Academy, US Merchant Marine Academy and others have reinstated instruction in celestial navigation. This requires measuring the height of the sun,...

I had a flight the next morning. Rather than wait and return with the group I walked to a dark lonely city street corner and  fired up the Uber app on my phone. The car was only two minutes away. Sweet. The app's map display showed the progress of the car as it came...

Editor's Note: Some folks in the FAA will dismiss the role of GPS in aviation and claim that commercial aircraft don' have the same dependencies as other modes of transportation. As with many claims of government officials who don't have the authority nor funds to do...

On the 26th of October NIST and IEEE hosted a workshop on “Timing Challenges in the Smart Grid” at the sprawling and attractive NIST campus in Gaithersburg, MD. Here are some quotes and observations from the morning and early afternoon sessions, and from a couple of...

The RNT Foundation has actively endorsed specific legislation to provide more resilient PNT services. In a letter to selected members of the Senate the foundation endorsed HR 5978 which would require the US Coast Guard to establish an eLoran system to serve as a...

Photo: By Kremlin.ru Despotic regimes have to be paranoid. Two recent news items show that the Russians are particularly and extremely concerned about the power that GPS and other satnav systems give to both nations and ordinary people. The first is the Russian...

The planet doesn't seem to care about how fast or slowly we think it should rotate. Perhaps it is a good reminder that we aren't really in charge of all that much and have to accommodate ourselves to the way the world really turns... Once again we are facing a leap...

Editor's Note: The below item is re-posted from "The National Interest." It is disappointing to see that, in all the discussions in academia, think tanks, and even by Defense Department officials, no mention is made of eLoran - the system the Deputy Secretary of...

Some really smart and clever people are figuring out how to navigate without GPS - or so their headlines claim. Take for example this recent post by the University of California, Riverside - No GPS, No Problem: Next-Generation Navigation UC Riverside Team is...

Editor's note: In June we posted a South Korean news item that contained much of this same information. The most significant difference with this news item is that in June the lawmaker making the fuss was from the opposition party. The one cited in this article is...

Editor's Note: Many futurists see the coming decade as the real dawn of the age of robotics and autonomous systems. This post from "Maritime Executive" seems to reinforce that.  It should also remind everyone how navigation is an invisible utility for all of these...

Blog editor's Note: Not a bad overview article on Kiplinger.com Two points, though.  First, the bit about "What's the value of oxygen?  GPS is oxygen" is from Greg Milner's book "Pinpoint - How GPS is changing technology, culture and our minds." I mentioned that in...

Blog Editor's Note: In 1998 President Clinton directed a study of the growing dependency on satellite navigation and timing systems. In 2001 the resulting report confirmed it was a problem, recommended studying upgrading Loran-C to be a complementary system, and...

Editor's note: The legislative progress on this important issue continues.  A link to the bill itself, HR 5978 Links to materials submitted to the Congressional Record associated with the bill: 2004 fact sheet on National Security Presidential Directive 39 directing...

Discussing his agency's efforts to protect GPS and the Positioning, Navigation and Timing (PNT) services it provides, a government official was recently quoted saying that a major problem was that the issues were decentralized and so many agencies were involved. His...

Editor's note: This is the first open press item we recall that discusses China's use of GPS jamming against US forces. GPS jamming and spoofing are often classified as "electronic warfare" by US officials instead of "cyber warfare."  We don't understand why that is...

Government officials tell us that the US Department of Homeland Security (DHS) is standing up a Program Management Office (PMO) for Positioning, Navigation and Timing (PNT) issues. The PMO will reside within the Office of Infrastructure Protection which is a component...

Military & Aerospace June 28, 2016 By John Keller Editor How much do you trust and rely on your personal GPS satellite navigation device to tell where you are or how to get to where you're going? It may be subject to GPS jamming. If you depend on GPS a lot, then...

Editor's Note: Jammers for every budget and use can be easily found  on the internet from sites like Jammerall.com. We thought that this item from IHS was worth repeating, though. KB Radar develops UAV-based SATCOM, navigation jammers Huw Williams, London - IHS Jane's...

A CEPT Electronic Communications Committee report from 2014 that was recently posted giving practical guidance for TDD networks lists four ways to provide essential timing and synchronization for cell phone networks.  From the report: GNSS – Main source used today,...
