Abstract:

The potential of using the Precise Point Positioning PPP with the Natural Resources Canada NRCan Ultra-Rapid products to serve as a short latency time-transfer tool is assessed. A specific experiment has been set up, where the NRCan Ultra-Rapid products, as well as all currently available International GNSS Service IGS products, are used in PPP time transfer between selected IGS stations co-located in timing laboratories. Results and relative merits are compared between products, in light of their respective delivery characteristics and in view of designing an automated near-real-time monitoring system to assist timing laboratories in their operational maintenance of frequency standards and timescale dissemination to external users.
