Abstract
An apparatus and method for detecting an antenna mispointing condition of an earth station. A noise floor detector, coupled to a received radio communications link signal, measures a noise floor of a selected frequency band in which no radio signals are normally present. A controller, coupled to the noise detector, detects an antenna mispointing condition when a signal strength of the received radio communications link signal is less than a predetermined signal strength and a difference between the measured noise floor and a baseline noise floor measurement is less than a predetermined difference.
