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: It was a privilege to participate in this event and meet with the attendees. A fascinating mix of experience and expertise from the US, Europe and Middle East. Selective Availability, IoT, Suez Canal Visit, Featured at Arab Institute of Navigation...

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...

Blog Editor's Note: The below article from Inside GNSS discusses an issue that many are trying to get their heads around. Europe has started to address it with their Radio Equipment Directive and the STRIKE3 project. This is going to be an issue to follow closely as...

Blog Editor's Note: GPS disruptions have brought down networks, disabled end use devices, and provided bad data to users which has been used and stored. Yet few in the cybersecurity field see it as something they are responsible for worrying about.  Good to see this...

Blog Editor's Note: Standards for Loran-C were effectively set by the US Coast Guard. This enabled receivers world-wide to use signals whether they came from Russia, China, Europe or the USA. SAE has assumed this role for eLoran. With South Korea implementing its...

Blog Editor's Note: Spoofing seems to have become the concern of the moment, almost eclipsing jamming/denial of service in the public consciousness. Certainly the idea of hazardously misleading information is more disturbing than no information at all. Interestingly,...

Blog Editor's Note: BZ (Well Done!) to the US Coast Guard for posting GPS problem reports on the internet for all to see and learn from. Reports from 2018 are available now (we counted 43), new ones will be added, as will reports from previous years. Members of the...

Blog Editor's Note: We just ran across this article from 2016. While it is a couple years old, it has some tidbits we had not seen before. For example that the Russian government is spoofing both GPS and GLONASS in Moscow. Also confirmation that this is related to...

Blog Editor's Note: Protection of GPS satellites must be a national priority. Probably even more important is protection of GPS signals. The nation has had policy for 14 years to do just that, but very little has been done. We are glad that Space Force, according to...

Blog Editor's Note: This article from the most recent Institute of Navigation Newsletter reflects the widely held belief that the current governance system for GPS/PNT in the US, which was established in 2004, has not been able to protect, toughen and augment GPS as...

Blog Editor's Note: Dag Pike is a navigator of note from both the old and new schools. We have always found his insights helpful on a variety of issues from boat handling to GPS.  The Daily Telegraph requires you subscribe to their site to access much of their...
