Global Navigation Satellite Systems Engineering, Policy, and Design
The American Transportation Research Institute (ATRI) released on January 25 its annual list highlighting the most congested bottlenecks for trucks in America.
Congestion chokepoints hurt the economy and the environment, so the ATRI uses GPS data collected each year to help identify times and locations that truckers will want to avoid.

The U.S. Naval Observatory Alternate Master Clock at 2nd Space Operations Squadron, Schriever AFB in Colorado. This photo was taken in January, 2006 during the addition of a leap second. The USNO master clocks control GPS timing. They are accurate to within one second every 20 million years (Satellites are so picky! Humans, on the other hand, just want to know if we’re too late for lunch) USAF photo by A1C Jason Ridder.

By Inside GNSSAs with the notion of “disruption,” unpredictability can be useful. A move in chess or go, for instance. Or in the case of cuisine — say, when usurping Taco Thursday with chicken tagine. Even in negotiations, an unanticipated gambit can change the outcome positively.
Sometimes, of course, unpredictability is in the immanent nature of things. Despite advances in meteorological technology and science, weather continues to prove fickle. Foreknowledge of earthquakes remains difficult to pin down in space and time.

After a successful first GSA Galileo Hackathon, the European GNSS Agency (GSA) is busy making plans for its next adventure in app building, scheduled to coincide with infoShare 2017, May 17-19 in Gdańsk, Poland.
Last year teams of passionate coders and geo-enthusiasts from around the world gathered to compete during the first event, which served as an opportunity to showcase coding skills, connect with the Geo-IoT (Internet of Things) app development community, and gain a competitive insight on what Galileo location-based services (LBS) can bring to your mobile device.

Miguel Mantiega Bautista talks about the ECA’s view on GNSS while attending the Navitec conference in Noordwijk.The first generation of the Galileo Program, at satellite and ground segment level, has been “an enormous success," according to Miguel Manteiga Bautista, who spoke with Inside GNSS last December at his office at the European Space Agency’s European Space Research and Technology Centre (ESTEC) in Noordwijk.

The BeiDou Navigation Satellite System (BDS) is China’s contribution to the world in the domain of Global Satellite Navigation System (GNSS). The BDS is being developed by the Chinese government, mainly through military departments, with key considerations for China’s national security, economic interests and social progress.

Washington has seen a lot of transitions, so even amidst political controversy it’s generally business as usual.
For the GPS community that business, at least in the near term, will likely center on changes in federal leadership — with many key appointments, like a new Secretary of the Air Force, still to be determined. In addition — even at this early stage when new lawmakers are still trying to find their offices — there are issues and opportunities worth watching in emerging legislation.

EquationsIncorporation of real-time synchronized phasor measurements in the control of power grids can play an important role in maintaining the overall closed-loop stability of the power system. In the past, instability in the power grid caused disturbances ranging from small local perturbations to severe large scale blackouts as can be seen from Figure 1. Currently, the synchronization achieved in measurements collected using devices known as supervisory control and data acquisition (SCADA) is not robust enough for efficient monitoring the power grid.

Passive hydrogen maser atomic clock of the type flown on Galileo, accurate to one second in three million years. ESA photoAt the traditional January media briefing in Paris yesterday (January 18, 2017), European Space Agency (ESA) General Director Jan Woerner was forthright in laying out the knowns and unknowns about the failed rubidium and hydrogen maser clocks onboard orbiting Galileo satellites, clocks that are absolutely crucial for accurate positioning.

After a yearslong wait the Federal Communications Commission (FCC) is asking for comments on whether it should allow signals from Europe’s Galileo satellite navigation system to be used for non-federal applications in the United States. The call for public feedback is part of a process to grant a waiver so that Galileo-capable receivers don’t have to be licensed in the United States.
