Innovation: Getting there safely with chip-scale atomic clocks

October 12, 2016By and

Better GNSS Navigation and Spoofing Detection with Chip-Scale Atomic Clocks It’s all physics. How things work, that is. You’ve heard me say that before in this column, but I suppose I’m a little biased (or realistic) as my first degree is in physics — applied physics, to be more precise. Mind you, some chemists might disagree that it’s all down to... read more

DARPA hosts Proposers Day on new atomic clock

January 13, 2016By

The Defense Advanced Research Projects Agency (DARPA) is holding a Proposers Day on Feb. 1 to inform potential contractors about the Atomic Clock with Enhanced Stability (ACES) program. ACES is a potential $50 million program that seeks to develop battery-powered atomic clocks that work to provide warfighters with synchronization and precision timing capabilities during navigation, communications, electronic warfare and reconnaissance... read more

The Internet of Everything: It’s All in the Timing

June 10, 2015By

40th Annual NIST Time and Frequency Metrology Seminar
The NIST T&F Metrology Seminar is one of a kind — easily the best in the world for time and frequency metrology. There are so many exciting discoveries concerning time and how time applies to our everyday lives, especially to GPS — all PNT systems actually. Consider that the NIST Time and Frequency distribution system delivers NIST Internet time over the Internet at the rate of 8 billion requests per day from servers at 25 locations across the United States. And that's just the beginning of this tale as old as time. read more

Bill Supports eLoran as GPS Backup

March 27, 2015By

A bi-partisan group of legislators led by Congressman John Garamendi (D-Calif.) has introduced a bill that would require the U.S. Secretary of Defense to establish a backup for GPS within three years using eLoran. The National Positioning, Navigation, and Timing Resilience and Security Act of 2015, H.R. 1678, was co-sponsored by Congressmen Duncan Hunter (R-Calif.), Peter DeFazio (D-Ore.), and Frank LoBiondo (R-N.J). Garamendi is the... read more

Dark-Matter Detectives: the Clocks Aboard GPS Satellites

November 18, 2014By

“Networks of correlated atomic clocks, some of them already in existence, such as the Global Positioning System, can be used as a powerful tool to search for topological defect dark matter, thus providing another important fundamental physics application for the ever-improving accuracy of atomic clocks,” write physicists Andrei Derevianko and Maxim Pospelov in the current issue of Nature Physics journal.... read more

The Adventure of the Atomic Clock

April 9, 2014By

In consulting my notebooks for the spring of 2014, I find many remarkable cases that engaged the attention of my intimate friend Mr. Sherlock Holmes. The intrigue into which we were drawn by the visiting American, Geo. P. Hess, probed the unforeseen effects of a launchpad fire, the mysterious slide to the right of two system segments, and the enigma of the vanishing leaders. read more

Passive hydrogen maser.

Orolia has finalized the contracts to supply Rubidium atomic clocks (Rubidium Atomic Frequency Standard, RAFS) and passive hydrogen masers to equip eight satellites for Galileo’s Full Operational Capability Phase II program. The two new contracts, totaling 14.5 million euros, follows the authorization to proceed received in June 2012 for the manufacture of these two types of high-precision clocks. Oriola brands... read more
