An advanced external beam steering controller (AEBSC) for use with a phased array antenna which requires only spherical coordinate pointing information to be supplied from a remote controller. The AEBSC uses the spherical coordinate pointing information, as well as stored information for the X, Y and Z axes locations of each specific antenna element of the phased array antenna, to generate actual phase shift values needed to be applied to each antenna element in order to point the antenna in accordance with a predetermined pointing angle. The invention significantly reduces the amount of electrical cabling required for communicating with the external controller, and also reduces the required data rate at which information must be supplied from the remote controller to the AEBSC.
