Abstract

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.

摘要

本论文通过实验评估了利用加拿大自然资源部（NRCan）超快速 GPS 产品进行精密单点定位（PPP）的方法，该方法可作为一种短延迟时间传递工具，以协助时间实验室进行频率标准的运行维护和时间尺度的传播。为了实现高效、近乎实时的时钟比较和监测目的，我们建立了一个自动化的数据交换和处理系统，为国际社会提供服务。
