  • Abstract
    The Ka band regenerative payload is a transponder of GSAT-4 satellite. It provides Narrow Spot Beams, Wide Bandwidth and small size of antenna for both transmission and reception. The Signaling Demodulator is a one of the important subsystem of regenerative Payload. This Signaling Demodulator was developed in-house for providing signaling information to provide communication between one spot beam to other. The demodulator software was developed for functionality of getting the signaling request from the user terminal & the processing of the request onboard.
