Blog Editor's Note: This piece from KPIX, the CBS affiliate in San Francisco, is a good popular summary of the challenges faced by America and other nations without a terrestrial backup and augmentation system. While not everything that uses GPS fails as soon as the...

Photo Peter Wong Blog Editor's Note: In May a drone show in Xi'an, China was disrupted by GPS jamming. About one third of the 1,300+ drones were affected and unable to keep their positions in the display formation. In the Hong Kong show reported on below, only 100...

Blog Editor's Note: When evaluating claims like this, we like to use the "NCIS Rule" - ask if the accused had the means, motive, and opportunity. The US military certainly has the means to spoof GPS, GLONASS and every other satnav system that drones might use. In an...

Blog Editor's Notes:  FCC rules require the licensing of non-federal receive-only equipment that operates with foreign satellite systems, including navigation systems. They also state that a waiver may be granted for non-US satnav signals, if the provider so requests....

Spoofing GPS – Now you see it, now you don’t! Thursday, November 8, 2018 14:00 until 15:00 EST ABOUT Russian EW ops have “relocated” over 600 vessels from their coastal waters to airports. Gamers have convinced Pokémon Go that they are thousands of miles away in...

Two recent reports to the US Coast Guard document persistent GPS disruptions within seven or eight nautical miles of the Saudi Arabian port of Jeddah. These follow well documented problems in the Black Sea, around Cyprus, off-shore of Syria, and in the vicinity of...

Blog Editor's Note: This is a good reminder of the importance of designing in cyber security.  Also the vulnerability of GNSS signals, and that no one is immune to disruptions. . . October 18, 2018 By Inside GNSS . A recent General Accountability Office (GAO)...

Blog Editor's Note: Bob Poole is a regular contributor to the respected industry journal "Air Traffic Management." He has often observed that a navigation and timing system that serves ALL modes of transportation would be much less expensive for the United States, and...

Reports of recurring GPS reception problems near Tacoma, WA in the US and the port of Plymouth in the UK have been received by the US Coast Guard Navigation Center, the agency that collates such reports from the public. See reports for 9/27/2018 and 10/2/2018. The...

Blog Editor's Note: NASA is rightly concerned about the future of space and keeping it usable. The immediate problem and the focus of much recent attention has been Low Earth Orbit (LEO). GNSS fly about ten thousand miles above LEO in Medium Earth Orbit (MEO), so it...

Blog Editor's Note: The US Coast Guard recently published its "Maritime Commerce Strategic Outlook." As the service looks forward, it recognizes maritime's dependence upon GPS for a wide range of things far beyond simple navigation. "MTS" is "Marine Transportation...

Blog Editor's Note: There seems to be a lot of talk these days about systems to complement and backup GNSS. We think that establishing a good set of criteria that focus on protecting a nation and its citizens by helping establish a rock-solid PNT architecture is a...

Blog Editor's Note: PNT is a worry for all navigation systems and navigators, especially for systems like drones and interconnected vehicles. This issue has not had a lot of public visibility in this industry. This may be partly due to an expectation that government...

At the Arab Institute of Navigation Conference, Cairo, Egypt Several themes have emerged from among the many and varied technical and policy presentations at this annual conference. First and foremost, of course, is that GNSS is a wonderful utility that provides the...

Blog Editor's Note: We are always glad to see government officials engage with an important issue. At the same time, 2018 marks the 14th year the US government has failed to act on its own mandates to protect and augment GPS signals. Studies and analysis do little to...

Blog Editor's Note: An excellent article that reflects an important shift in the way people are thinking about this problem. We have recently been talking to very senior officials at the Department of Defense, Department of Homeland Security, and the White House.  All...

Blog Editor's Note: Authentication is a real and important issue, whether its something we hear on the news or PNT information. In a world where purported data is ubiquitous, how do we know what is real. The United States Air Force vouches for the quality of the...

We depend upon GPS signals for so many important things, it's often difficult to think of them all.  We were reminded of just how important some of these uses are when we read this problem report on the US Coast Guard's website: "My son wears a GPS watch due to the...
