Abstract

Simultaneous two-way time transfer experiments via satellite symphonie, in which National Physical Laboratory, New Delhi (NPL), Space Applications Centre (SAC), Ahmedabad and Madras Earth Station, Madras (MES) participated, are reported in this paper. The uncertainties involved in alternate one-way mode of clock synchronization reported earlier were removed and a much improved precision and accuracy was achieved. In addition, the results obtained in a Round Robin method, where one station transmits and the other two receive between NPL, SAC and MES are also presented.
