First evaluation of a rapid time transfer within the IGS global real-time network

This paper presents a preliminary assessment of the quality of station clock states, estimated in "near-real-time" by the process running at Natural Resources Canada (NRCan). The evaluation is mainly of the short and long-term frequency stability and the accuracy thereof with respect to the IGS rapid and final clock products, provided by the International GNSS Service (IGS). The aim of this work is to evaluate the feasibility of time and frequency transfer in real-time and to show the potential of such a process once access to a global IGS network of real-time GPS tracking stations becomes a reality
