説明
The recent development of optical frequency standards has been performed quite rapid and the better uncertainty than that of microwave frequency standards will be realized in very near future. We are evaluating a one-dimensional 87 Sr optical lattice clock developed and located at the University of Tokyo, Tokyo, by using UTC(NMIJ) generated at NMIJ, Tsukuba. The baseline length between those two sites is about 50 km. We constructed a time and frequency transfer link using GPS carrier phase method for this link. We use GIPSY software and a newly developed one for data analysis. Our developed one works in real time using carrier phase data and broadcast navigation data which are obtained from the carrier phase receivers.
