The Global Positioning System (GPS) is not only a navigation system, it is also a time-
transfer system. As a time-transfer system it provides stability very close to one part in ten to …

When neglecting calibration issues, the accuracy of GPS-based time and frequency transfer
using a combined analysis of code and carrier phase measurements highly depends on the …

We have conducted several time-transfer experiments using the phase of the GPS carrier
rather than the code, as is done in current GPS-based time-transfer systems. Atomic clocks …

An absolute calibration technique is developed for geodetic Global Positioning System
(GPS) receivers. An uncertainty budget for the system (receiver, cables, connectors …

This work covers a broad range of different topics such as orbit modeling, orbit validation
using satellite laser ranging observations, time transfer, station coordinates and velocities …

We have conducted global positioning system (GPS) carrier-phase time-transfer
experiments between the master clock (MC) at the US Naval Observatory (USNO) in …

The Royal Observatory of Belgium (ROB) developed the software Atomium to perform GPS-
based time and frequency transfer. Originally dedicated to perform Precise Point Positioning …

Modern dual-frequency global positioning system (GPS) receivers are capable of providing
direct measurements of both L 1 C/A (C 1) and P code (P 1) without the use of the Y-codes …

GPS-based geodetic time and frequency transfer are based on a consistent modeling of
both code and carrier phase measurements, and is presently widely recognized for its high …

We have conducted several time-transfer experiments using the phase of the GPS carrier
rather than the code as is done in current GPS based time-transfer systems. We connected …
