The Time Link Between CSAO and CRL

Abstract

There are and will be a few techniques for time link between CSAO and CRL. The TWSTFT was set up in October 1998 via a Japanese communication satellite. The CSAO-CRL TWSTFT data have been accumulated for more than 1 year since the date when the link was established. The regular operations for the time comparison are well done in 30 minutes twice a week. The GPS Common View has been a regular time link between CRL and CSAO for TAI computation since June 1996. It is expected that there will be a third technique for the time link with GPS/GLONASS multichannel receivers in the near future.
