Multi-Receiver GPS-Based Direct Time Estimation

Multi-Receiver GPS-Based Direct Time Estimation

Incorporation 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.

ESA Puts Brave Face on Galileo Clock Failures

At 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.

FCC Seeks Comments on Allowing Galileo Use in U.S.

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.

OCX Gains Ground With Help From Private Sector Computer Wizards

Though the schedule is still uncertain, progress is being made on completing the new GPS ground system, said Air Force Secretary Deborah Lee James, who credited a crack group of private-sector computer wizards with helping get the program back on course.

Calling the GPS Next Generation Operational Control System (OCX), a "terribly, terribly important program," James said, however, she still did not consider the software-focused effort to be "out of the woods."

Vidal Ashkenazi Awarded OBE for GNSS Role in Services to Science

Nottingham Scientific Ltd (NSL) has announced that the company’s founder and CEO, Professor Vidal Ashkenazi, has been named an officer of the Order of the British Empire (OBE ) in the 2017 New Year’s Honors List for “Services to Science.”

The OBE was created by King George V in 1917 and is awarded by the ruling monarch of the United Kingdom, currently Queen Elizabeth II. The honor recognizes distinguished service to the arts and sciences, public services outside the civil service, and work with charitable and welfare organizations.

Defense Authorization Bill Signals Full GPS Funding, Pushes GPS Back-Up

Yesterday (December 23, 2016) President Obama signed the National Defense Authorization Act (NDAA) for Fiscal Year 2017, a $619-billion bill with a number of provisions affecting satellite navigation.

The legislation (S. 2943) fully authorizes the administration’s requests for all the elements of the GPS program — and signals indirectly that appropriators eventually will provide comparable support — although the NDAA does put additional requirements on those developing the new GPS ground system.
