FREQUENCY REFERENCE IN VSAT

A low cost technique of frequency reference distribution within a VSAT network is discussed. This technique allows the use of a modestly fre quency stable oscillator as the master frequency reference in the hub of a star-connected VSAT network. The need for extremely frequency sta ble OCXOs in VSATs to completely avoided. This technique was successfu lly incorporated in the early commercial VSAT networks. It contributes partially to the low cost nature of some of the VSAT networks availab le today.
