Abstract
Using a phased array of antennas on the ground to transmit signals to a distant spacecraft requires a method for keeping the carrier phases properly aligned at the separate antennas. One approach is to implement a receiving capability at each antenna along with the transmitting capability, and to use measurements of the relative phases of received signals to align those of the transmitted signals. This can be effective if phase errors are similar in the two directions. An architecture that facilitates this approach is proposed.
