SRRA: SMART REDUNDANCY RECONFIGURATION ALGORITHM FOR COMMUNICATION SATELLITE PAYLOAD

Abstract

Redundancy is provided by using multiport switches which are connecting equipment in communication satellite payload systems. In case of a failure, signal path is re-routed by changing suitable switch positions. Smart Redundancy Reconfiguration Algorithm (SRRA) is a novel algorithm, able to model any payload system and to find paths recursively to redundant equipment. Results of the SRRA are verified by means of comparing them to those of the ICAREF commercial software which is currently being used in TURKSAT-3A satellite operations. SRRA can find all paths connecting given input(s) to any output(s) by taking number of interruptions and number of switches crossed constraints into account.
