Time Code Dissemination Experiment Via the SIRIO-1 VHF Transponder

E. De Toma, G. Gobbo, S. Leschiutta

Abstract:	The advantages of employing synchronous satellites for time dissemination are well known, both in terms of coverage and continuity of service over the covered area. Many synchronous telecommunications satellites carry onboard VHF transponders; these are mainly used as ranging transponders during the launch phases and as beacons or telemetry backup transmitters during the satellite operational life, in which the ranging capabilities of these transponders are seldom used. The aim of the experiment described in this paper aims to test the possibility of using these VHP transponders, in their ranging configuration, as repeaters to disseminate time information over a wide area. The experiment, proposed by the Istituto Elettrotecnico Nazionale (Torino, Italy), was performed during the summer of 1980, with the cooperation of Telespazio S.p.A., and using the VHF transponder onboard the synchronous experiment telecommunications satellites SIRIO-1.
