ABSTRACT:
A concentric arrangement of multiple spacecraft antennas mounted symmetrically about the yaw axis of rotation or center of gravity of the spacecraft that provides the capability for spacecraft with multiple antennas to maneuver without introducing errors into navigation signals and without adding complexity to the spacecraft and/or remote terminals. An arrangement of multiple spacecraft antennas comprising a first antenna array mounted on a spacecraft bus, the first antenna array having a center located on a yaw axis of the spacecraft and a second antenna array mounted on the spacecraft bus, the second antenna array having a coincident or overlapping frequency band as the first antenna array and mounted symmetrically about the yaw axis of the spacecraft in a central portion of the first antenna array so as to be concentric with the first antenna array.
