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 frequency stable oscillator as the master frequency reference in the hub of a star-connected VSAT network. The need for extremely frequency stable OCXOs in VSATs is completely avoided. This technique was successfully incorporated In the early commercial VSAT networks. It contributes partially to the low cost nature of some of the VSAT networks available today.<
