ABSTRACT:
A satellite communications system is so arranged that different communications channels can be set up without interfering with each other. A reference pilot signal is set to enable errors and frequency shifts in the system to be measured, so that when a communications channel is set up due allowance can be made. This approach allows channels to be accurately placed more closely together.
