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 ...

Controlled reception pattern antennas (CRPAs, pronounced “serpers”), adaptive antennas, null-steering antennas, beamforming antennas… You’ve probably heard of at least one of those terms in any ...

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

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.

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) ...

For this column, the file of bench marks provided on the NGS Geoid18 web page were combined with the published ellipsoid, orthometric, and Geoid18 heights from NGS’ datasheet. The difference between ...

Automotive navigation is highly connected and capable of dynamically using high-resolution map information and vehicle and environmental data from the cloud.

In the early 19th century, as the sun moved across Britain from east to west, people set their clocks to local mean time, so that noon in Greenwich would occur about 16½ minutes before noon in ...

GPS applications are vulnerable to signal interference, spoofing and degraded or denied services. Both intentional — jamming — and unintentional signal interference can cause inaccurate PNT and poor ...

In this cover story on simulators, we discuss these challenges with experts at four simulator manufacturers including CAST Navigation, Spirent Federal, Spirent Communications, Safran Federal Systems ...

“The inverted geospatial pyramid” graphic depicts how the entire $1 trillion geospatial economy is supported and dependent on geodesy, and how it’s close to collapsing without an increase of support ...

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 ...
