Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
113 words
THE METHOD OF TRANSMITTING A RADIO SIGNAL BETWEEN FIRST AND SECOND SPACED-APART STATIONS VIA AN ORBITING RELAY SATELLITE STATION, COMPRISING THE STEPS OF: TRANSMITTING A SIGNAL-MODULATED CARRIER FROM SAID FIRST STATION TO SAID SATELLITE STATION AT AN INITIAL CARRIER FREQUENCY WHICH IS RELATED TO THE LOCATION AND ORIENTATION OF SAID SATELLITE STATION WITH RESPECT TO SAID SECOND STATION; RE-TRANSMITTING THE CARRIER RECEIVED AT SAID SATELLITE STATION FROM SAID FIRST STATION TO SAID SECOND STATION BY MEANS OF DIRECTIONAL ANTENNA WHOSE BAM ANGLE IS A FUNCTION OF THE FREQUENCY OF SAID CARRIER; AND VARYING SAID INITIAL FREQUENCY OF SAID CARRIER IN RESPONSE TO CHANGES IN THE ORIENTATION AND ORBITAL PATH OF SAID SATELLITE STATION.
Claim 2
Independent Claim
113 words

Claim 3
Dependent Claim
83 words
THE METHOD AS DEFINED IN CLAIM 1 INCLUDING THE STEPS OF: TRANSMITTING A TRACKING CARRIER FROM SAID FIRST STATION TO SAID SATELLITE STATION; RE-TRANSMITTING SAID TRACKING CARRIER FROM SAID SATELLITE STATION; RECEIVING SAID RE-TRANSMITTED TRACKING CARRIER AT SAID FIRST STATION; AND SHIFTING THE FREQUENCY OF SAID TRACKING CARRIER TRANSMITTED FROM SAID FRIST STATION TO OBTAIN MAXIMUM SIGNAL STRENGTH OF THE RE-TRANSMITTED TRACKING CARRIER RECEIVED AT SAID FIRST STATION AND THEREBY OBTAIN AND INDICATION OF THE ORIENTATION AND ORBITAL PATH OF SAID SATELLITE STATION.
