Abstract

A phased antenna array (20) generates a first field of view (42) and a second field of view (45). First and second motors (26, 29) are coupled to the phased antenna array to rotate the first and second fields of view about first and second axes (27, 30), respectively, to concurrently track first and second space vehicles (12, 13). A third motor (33) rotates the phased antenna array around a third axis (34) to equalize the received magnitude of first and second signals (VC1, VC2) propagating within the first and second fields of view.
