Until now, however, the minimum number of GPS satellites needed to determine the exact position of a mobile phone or other navigation device has remained a matter of conjecture.

After years of delays, only one GPS III satellite has launched so far. To complete the “A block” of the constellation, nine more are scheduled to launch by 2023. hide ...

A NASA satellite that’s been orbiting as space junk since 1967, Relay 2, emitted an unexpected, powerful radio burst that ...

Designed in the 1970’s, the computer systems on the GPS satellites represent weeks using a 10-bit number. This has a maximum value of 1024. After 1024 weeks have passed, or 19.7 years, the ...

Leveraging GPS satellites could be the key to ensuring mobile antennas remain effectively aligned, according to Vodafone’s ...

Here, UNSW academics Professor Andrew Dempster and Dr. Craig Roberts give a sneak peek what people can expect from GPS over the next 50 years.

The satellite will further experiment with on-orbit re-programable capability, essentially allowing NTS-3 to broadcast GPS signals in different, frequently changing waveform guises like a software ...

Tuning into a GPS satellite is nothing new. Your phone and your car probably do that multiple times a day. But [dereksgc] has been listening to GPS voice traffic. The traffic originates from COSPAS… ...

We tested affordable and high-end watches to see which located satellites quickest, ... Considering this history, I wondered if a higher model number correlated with getting a quicker GPS signal.

This satellite masking technique appears to be a clever way to thicken the fog of war in the face of ever-increasing reconnaissance capabilities, but experts fear that it might spread that fog ...

Thanks to the atomic clock, satellites send very accurate times, but the big issue lies with the accuracy of the clock in the user's device—whether it's a GPS navigation device, a smartphone, or ...
