Precise Time and frequency dissemination to Indian Deep Space Network from NavIC PTF

ISTRAC's Indian Deep Space Network (IDSN) provides telemetry, tracking and command services for interplanetary missions. IDSN requires a precise reference with frequency stabilities of that of atomic clocks in order to make precise measurements. An elaborate dissemination network was designed and realized to provide precise time and frequency to IDSN, co-located with NavIC Precise Timing Facility (PTF), via copper RF cables. The design ensures that there are no single point failures. This paper dwells on the challenges in realization of the dissemination network and the finally realized architecture of the network.
