Abstract

Long baseline time comparison is time comparison between two stations over 1,000 kilometers through time transfer technology. Currently, international main method of long baseline time comparison is GPS CV and TWSTFT. The former is low-cost and easy to implement; the latter requires more expensive equipment to build the link, but it is high accuracy. This article Introduces GPS common-view (GPS CV) link and satellite two-way comparison (TWSTFT) link of NTSC; By using mathematical methods and software, processes the data of GPS CV and TWSTFT between NTSC and Technology Laboratory of Physics, Germany (PTB), analyzes the precision and makes some recommendations on their application at the end of this paper.
