Precise Time Dissemination Experiment Using the ATS-1 Satellite.

Abstract

A precise time transfer experiment using the Application Technology Satellite (ATS) as a link between a master and slave station achieved an accuracy of 50 nanoseconds one sigma. The technique is inherently capable of transferring precise time on a real time basis from a master time station to a number of slave stations. A conventional pseudo random noise (PN) code is used because of its spread spectrum properties. The low energy density and noise like signals can be transmitted coexisting with other transmissions without interference. Thus, the time transfer could be achieved via an existing satellite service.
