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 ...

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 ...

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.

Do you have a list of free sources of RTK base station data in the United States? Compile here is a comprehensive list, applicable to all U.S. residents.

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 ...

The United Kingdom’s Minister for Science, Research, Innovation announced in Parliament today a 10 point “policy framework” for advancing positioning, navigation, and timing (PNT).

Review the history of the GLONASS program, its current status and an overview of the plans for the immediate future of the satellite constellation.

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) ...

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 ...

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

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 ...
