Global navigation satellite systems need a stable and robust system time in order to provide services with high accuracy. A wellestablished approach for the generation of a time scale is the composite clock method. Differently from single clock appro

Clock ensembling is a well-established concept for creating robust and stable time frames, e.g. it is used to define the Universal Time Coordinated as well as the GPS system time. In order to reference Global Navigation Satellite Systems (GNSSs) to a

This paper compares the estimation results of two composite clock algorithms based on Kalman filtering of measured clock differences: the original Jones–Tryon algorithm and Greenhall's covariance-reduction modification. The theory is carried out fo

The performance of the GPS constellation is modeled using four possible ensembles of monitor site clocks and two different versions of the composite clock algorithm. The analysis of our previous paper is scrutinized; the conclusion remains that the i

The GPS system is simulated in three scenarios, so as to estimate how its performance would be improved by more stable ground clocks. One scenario is an approximation to the current system. The second replaces the cesium frequency standards at the mo

The operational implementation of the ensemble Kalman filter Composite Clock (CC developed by K. R. Brown), is subject of the paper. Although the mathematical background of the CC is well-known, its autonomous and robust operation in a clock laborato
