1. A reflector array comprising:
a base;
a rotating support pivotally coupled to the base such that the rotating support is rotatable relative to the base in at least a first direction;
an array actuator comprising a rotating element coupled to the rotating support, the rotating element defining an array axis of rotation of the rotating support;
a plurality of reflectors attached to the rotating support such that the plurality of reflectors rotate in unison in conjunction with one another relative to the base as the array actuator rotates the rotating element about the array axis of rotation, wherein the plurality of reflectors comprises:
a first reflector coupled to the rotating support via a first reflector support element; and
a second reflector coupled to the rotating support via a second reflector support element, wherein the first reflector support element and the second reflector support element are rotatable to adjust angles of elevation thereof; and
one or more elevation adjustment actuators rotating the first reflector support element to adjust an elevation angle of the first reflector and the second reflector support element to adjust an elevation angle of the second reflector.
