ABSTRACT:
A loop-around doppler canceling loop is employed between a master ground minal or node and a slave ground terminal or node for translating a doppler-free reference to the slave terminal by having a local voltage controlled oscillator (VCO) of frequency f at the master terminal lock to a frequency f.sub.o =f.sub.d where f.sub.o is frequency of the primary standard reference clock 8 at the master terminal and f.sub.d is the two-way doppler frequency that exists during transmission between the master and slave ground terminals by way of satellite.
