Abstract
A device and method for tracking satellites and handing off from one satellite to another includes a linear phased array antenna capable of generating and receiving a radio signal beam and electronically pointing the beam, a first motor for tilting the antenna to mechanically point a radio signal beam generated with the antenna, a second motor for spinning or rotating the antenna to mechanically point the beam, and a controller for controlling the electronic and the mechanical pointing of the beam. The directions of the electronic and mechanical pointing of the beam is performed by selecting a certain angular profile for the second motor from the start point to the end point of the path and calculating a path of a satellite to be tracked from a start point to an end point.
