Automated signal measurement in a satellite communication system
First Claim
1. A method for performing signal measurements in a radio communications system, the method comprising:
- transmitting a signal having a predetermined waveform, wherein the signal is analyzed to output a measurement value that is packaged into a message; and
automatically receiving the message in response to the transmitted signal.

Abstract
An approach for providing signal measurements over a radio network is disclosed. A signal measurement means analyzes a signal that has a predetermined waveform from a terminal within the radio network and to output a measurement value. A server, which is coupled to the signal measurement means, is configured to prepare a message containing the measurement value for transmission to the terminal. The measurement value is used to selectively adjust antenna position of the terminal. The present invention has particular applicability to performing signal testing (e.g., cross-polarization testing) in a two-satellite system to achieve accurate antenna pointing, as well as efficient validation of correct installation and revalidation of previously installed antennas.
