摘要

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 Web application for GNSS data processing developed by GMV in Madrid, Spain. magicGNSS allows the users to perform a wide range of calculations and analyses related to GNSS, from the evaluation of performances at user level, to the computation of precise GNSS orbits and clocks, including the calculation of precise receiver coordinates. The time and frequency transfer capabilities of the network solution (named ODTS) are evaluated and compared to PPP solutions as well as to other time transfer results. The possibility to use magicGNSS as an almost near-real-time tool for the comparison of atomic clocks and time scales located in timing laboratories is also addressed.
