The European Space Agency (ESA) has selected Rocket Lab Corporation to launch a dedicated Electron mission, marking the first time the company will deploy satellites for ESA’s next-generation ...

Operational Anti-Jam Units With some images courtesy of my friends at Raytheon, let’s look at a few examples of deployed military CRPA hardware over the years. The GAS-1 system entered service in the ...

Safran Electronics & Defense has introduced BlackNaute, a new autonomous positioning, navigation and timing (PNT) system.

Timing from atomic clocks is now an integral part of data-center operations. The atomic clock time transmitted via Global Position System (GPS) and other Global Navigation Satellite System (GNSS) ...

D evelopers and manufacturers of GNSS receivers have always needed to simulate the signals from GNSS satellites to test receivers in their labs and in the field. Now, as the vital role of GNSS for ...

The National Academies of Sciences, Engineering and Medicine (NASEM) has issued a report discussing whether a terrestrial wireless network proposed by Ligado Networks — and approved by the Federal ...

You may have heard about “NMEA data” with respect to GPS. NMEA is an acronym for the National Marine Electronics Association. NMEA existed well before GPS was invented. According to the NMEA website, ...

The box titled “Summary of Overall fit of Geoid18” provides a summary of the fit of residuals of Geoid18 from the NGS GEOID18 technical details document. Looking at the CONUS overall values, the ...

A tragedy in 1999 spurred development of an entirely new type of positioning and location technology. “This project started with the Worchester, Massachusetts, warehouse fire,” said William Stout, ...

The main critical applications for GNSS timing can be roughly grouped by the accuracy they require — but they are changing. “For example, for cellular systems up to 30 ns jitter used to be enough,” ...

In the past few years, said Thomas, Racelogic “had to suddenly invent 15 new signals.” It makes a record-and-replay system — “You put a box in a car, on a bike, in a backpack, or on a rocket, and you ...

Clocks are at the heart of GPS. Advances in space-qualified atomic clocks that kept time to within 10 nanoseconds over a day were a key development that made GPS possible. It turns out that GPS must ...
