In this paper, we investigate a possible network solution, similar to the IGS Analysis Center solutions, that can be easily managed by a network of timing institutes to solve for all the clock differences (in addition to other quantities) in a unique system to understand the feasibility and the advantages of this approach in time and frequency transfer. The investigation is based on a tool called magicGNSS, which is a ...
The performance of the Galileo space-borne clocks is of importance for navigation and integrity at the corresponding user level. Clock estimation and prediction errors are directly mapped into the User Equivalent Range Error (UERE). The clock quality also affects the integrity performance of the Galileo system: clock "feared events," such as frequency and phase jumps, have to be characterized and adequate barriers built against them. In addition, the clocks operate ...
The future European radio navigation system Galileo will use its own time scale for the synchronization and dissemination of the predicted satellite clocks. Broadcast satellite clock predictions must be referred to a common and stable time reference in order for the user to be able to obtain an accurate positioning solution. The new Galileo time scale is called Galileo System Time (GST) and is the equivalent of the GPS Time ...
