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 ...

This article is based on a presentation to the National Space-Based Positioning, Navigation and Timing Advisory Board in June 2015. The study reported on at the meeting was requested by the National ...

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 ...

In the simple engineering analysis below, we consider the problems that would have arisen if the engineers had ignored relativity in their design of GPS. The issues related to positioning and time ...

The figure in the box titled “GEOID18 Conversion Surface in cm” is the surface that represents the difference between NAVD 88 as a datum and the geopotential (geoid) surface used in the gravimetric ...

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.

“There are three kinds of lies: lies, damn lies, and statistics.” So reportedly said Benjamin Disraeli, prime minister of Britain from 1874 to 1880. Almost as long ago, we published the first article ...
