Description
Summary:This paper experimentally evaluates the assessment of precise point positioning (PPP) using the Natural Resources Canada (NRCan) Ultra-Rapid GPS products to serve as a short latency time-transfer tool to assist timing laboratories in operational maintenance of frequency standards and time scale dissemination. An automated data exchange and processing system has been set up to serve the international community for efficient, nearly real-time clock comparison and monitoring purposes.
