1. A method of communication for an antenna assembly comprising a base structure and a support structure rotatably coupled with the base structure about a first axis, the method comprising:

  • tracking a first satellite for communication via a first antenna that is rotatably coupled with the support structure about a second axis, the first antenna having a first boresight, wherein tracking the first satellite comprises rotating the support structure about the first axis and rotating the first antenna about the second axis using a driven angular rotation about an axis that is non-coincident with the second axis;

    determining to switch from communications via the first antenna to communications via a second antenna that is rotatably coupled with the support structure about a third axis, the second antenna having a second boresight, wherein a projection of the second boresight on a plane perpendicular to the first axis is separated by an angle from a projection of the first boresight on the plane perpendicular to the first axis; and

    tracking a second satellite for communications via the second antenna, wherein tracking the second satellite comprises rotating the support structure about the first axis and rotating the second antenna about the third axis using a driven angular rotation about an axis that is non-coincident with the third axis.
