| 摘 要： | GPS PPP时间传递是国际权度局守时实验室最主要的高精度时间比对手段之一。介绍了GPS PPP时间比对的基本原理,利用RTKLIB实现GPS PPP时间比对,并实例分析验证了BRUX、IENG、OPMT与PTBB的时间比对结果。实验结果表明,利用RTKLIB进行时间比对的RMS为0.1～0.2 ns,天频率稳定度为1.5×10-15～2.5×10-15,时间比对结果与IGS最终钟差具有较好的一致性。

| Abstract: | GPS PPP time transfer is one of the most important high precision time comparison methods for the international authority's punctuality laboratory. The basic principle of time comparison of GPS PPP is introduced, and the time comparison of GPS PPP is proposed by RTKLIB, then the time comparison results of BRUX, IENG, OPMT and PTBB are verified by examples. The experimental results show that the RMS of time comparison using RTKLIB is about 0.1-0.2 ns, and the stability of the day frequency is about 1.5×10-15-2.5×10-15, The result of time comparison is in good agreement with IGS's final clock offset. |
