GPS accuracy relies on Einstein's relativity theories to correct satellite timing errors that would otherwise cause 6+ mile ...

We’ve seen a few H-bridge circuits around these parts before, and here’s another application. This time we have an Old Train ...

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

NTP is one of the most interesting and important, but all to forgotten, protocols that makes the internet tick. Accurate ...

Losing GPS would mean losing a lot more than Google Maps. The technology is integrated into everything from lights that turn ...

With workout tracking, heart rate monitoring, and sleep insights, this $70 Fitbit deal makes goal-setting easier.

Carrier synchronization, Mark Persons writes, can be applied to alleviate co-channel interference between two AM radio ...

In this video, we break down how GPS determines your position using satellite timing, atomic clocks, and distance calculations. We also explore the real world sources of error, from atmospheric ...

NIST restored the precision of its atomic clocks after a power outage caused by a power outage disrupted operations. Discover ...

Abstract: Dual-frequency Time Transfer Unit (TTU) using GLONASS and GPS signals developed at "Russian Institute of Radionavigation and Time" JSC (RIRT) is intended for determining the offset between ...
