Abstract:	The U#S-Navy Navigation Satellite System termed as NNSS offers a unique worldwide facility for the precise Time Synchronization. To take the advantage of such a facility for tracking Indjan Satellites, space Applications Centre (SAC) has developed a simple Timing receiver . Using this Timing Receiver first the internal time consistency of NNSS was studied and then its performance to synchronize tjme was compared with that of National Time Standard. This paper describes in detail the methodology of data analysis, results and the various sources of error which affects the time transfer accuracy. The main source of error was found to be the receiver delay which varies with signal strength. It is possible to apply this delay correction empirically provided signal strength is recorded.
