发明名称 SATELLITE-BORNE ANTENNA ACQUISITION TRACKING DEVICE
摘要 PROBLEM TO BE SOLVED: To solve the problem wherein, when two tracking receivers are loaded in order to acquire a redundancy configuration, the satellite mass is increased because two calibration devices are loaded in an antenna acquisition tracking device, and the problem wherein difference signal input which is an input condition of the tracking receiver when the antenna gain maximum direction agrees with the beacon wave arrival direction can not be calibrated in the RF terminal state. SOLUTION: This device has a constitution wherein, as for a calibration signal to be inputted into a sum signal system of the tracking receiver 2, a sum signal 11 outputted from an antenna 1 for receiving the beacon wave is inputted through a directional coupler 3 and a switch 4, and as for a calibration signal to be inputted into a difference signal system of the tracking receiver 2, the sum signal 11 outputted from the antenna 1 for receiving the beacon wave is branched by the directional coupler 3 by utilizing a switch for switching a redundancy system of the tracking receiver 2, and then inputted through a phase shifter or connected to a terminator 8.
