Recent changes in hardware and standards make one-meter accuracy possible, in some cases as soon as this year. The transcript of a talk given to Android developers earlier this year, this article ...

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.

Positioning, navigation and timing (PNT) orbs guide 50-ton robots carrying containers at the Ports of Auckland. In a world-exclusive report, GPS World visited with officials at the Ports of Auckland, ...

Unmanned aerial vehicle (uav) used in the spoofing tests; owned by the University of Texas. A radio signal sent from a half-mile away deceived the GPS receiver of a UAV into thinking that it was ...

We’ve heard a lot in the news recently about GPS spoofing, mostly centred on the story of ship spoofing in the Black Sea. Between June 22-24, a number of ships in the Black Sea reported anomalies with ...

This update to a seminal article first published here in 1998 explains how statistical methods can create many different position accuracy measures. As the driving forces of positioning and navigation ...

According to the Russia and CIS Radionavigation Plan, the terrestrial Chayka system, a version of Loran-C, is maintained to protect their homeland with navigation and timing services when signals from ...

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 ...

More Is Better The technique of precise point positioning (PPP) is making inroads in the positioning industry. However, one issue hampering its more widespread adoption is the convergence time ...
