There was a time when for time-and-frequency geeks this would have been a difficult job, but with the advent of GPS satellites overhead carrying super-accurate atomic clocks it’s surprisingly ...

and as a result they can also be used for things like this incredibly accurate frequency reference. This project is what’s known as a GPSDO, or GPS-disciplined oscillator. Typically they use a ...

Johnson has a B.Sc. in electronic and electrical engineering from the University of Surrey in Guildford, United Kingdom. “Multi-Frequency Precise Point Positioning Using GPS and Galileo Data with ...

It does this by using ... centimeters—by way of dual-frequency receivers. That’s crazy considering the satellites they use are, y’know, in space. Modern GPS equipment is capable of lots ...

This, however, seems to be fixed now with as many as 30 L5 satellites in orbit, enough to mass-market the technology Xiaomi is using. We are not sure who’s providing the Dual-frequency GPS chip ...

The document is designed to support validation of airborne requirements when using dual-frequency GPS, Galileo and satellite-based augmentation system (SBAS ... development of dual-frequency ...
