Modern satellite constellations such as OneWeb, Starlink and CENTISPACE promise global communications and navigation capabilities using low-Earth orbit (LEO) constellations. However, their precise ...

Recent eVTOL innovations, FAA-certified autonomous flight systems and UAV testbeds are reshaping urban air mobility and cargo automation.

JAVAD GNSS, a global provider of high-precision GNSS solutions, and Inertial Labs, a VIAVI Solutions Company, have entered a strategic partnership to integrate Inertial Labs’ IMU-P modules with ...

You’ve probably heard of at least one of those terms in any discussion around GPS anti-jam technology for defense. Because they are all terms that describe essentially the same thing: a specialized ...

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) ...

Engineers-turned-sleuths in Moss Landing Harbor, California, had a similar clue to go on: the tracks of a GPS jammer across a spectrum analyzer. For months, the elusive culprit had jammed GPS signals ...

You may have heard about “NMEA data” with respect to GPS. NMEA can be confusing because there are a few NMEA messages, not just one.

What happened is open to educated conjecture. In this column, I’ll briefly cover the history of spoofing, its basic techniques, some spoofing tests that we conducted, and then return to the infamous ...

Though marvelous, GNSS are also highly vulnerable. eLoran, which has no common failure modes with GNSS, could provide continuity of essential timing and ...

China’s BeiDou GNSS is newer, has more features, is more accurate, and has more satellites in the skies of more nations than the venerable U.S. GPS, according to Sarah Sewall, Executive Vice President ...

GPS signals are so weak, they cannot be used reliably where they are obstructed. But if the satellites were much closer, their signals would be much stronger.
