Passive hydrogen maser atomic clock of the type flown on Galileo, accurate to one second in three million years. ESA photo.Speakers at last month’s 9th Annual Conference on European Space Policy in Brussels wasted no time in addressing the somewhat worrying failure of a number of Galileo onboard clocks, as revealed by European Space Agency Director General Johan-Dietrich Woerner at a press briefing earlier in January in Paris. He made clear at the time that the clock failures, while indeed troubling, had had no effect on the operational integrity of the Galileo system.

Because GPS and other GNSS are critical to the nation’s infrastructure, the U.S. Department of Homeland Security (DHS) is testing an augmentation system and developing new requirements to protect it, a DHS official told the U.S. Department of Transportations’s Civil GPS Service Interface Committee (CGSIC) meeting this week in Portland, Oregon.
Gaylord National Resort and Convention CenterThe National Space-based Positioning, Navigation, and Timing (PNT) Advisory Board is comprised of experts from outside government that are tasked with developing recommendations for the PNT EXCOM to consider in making GPS services more effective and accessible to users in all domains and sectors. Attendance is open to the public.
