Abstract

A system for aligning two ground-based antennae (100, 110) or a ground-based antenna (100) and a satellite antenna (110), for use in military and civilian settings, in which a visual display is generated showing a graphical representation of the antennae including graphical representations indicating both the axis of the main lobe (102) and the approximate radiation pattern (414) of the antennae, superimposed over a live imaging of the local terrain. The alignment is achieved when the graphical representations of the main axis and radiation patterns of the two antennae align with each other.
