Reconfigurable Satellite Payload Model based on Software Radio Technologies

Within this article, we look at some of the improvements which can be obtained when Software Defined Radio (SDR) technology is used in order to build satellite payloads. Afterwards, we present a SDR on-board processing model where flexibility, reconfiguration and self-configuration are considered as the prime targets. This model is explained by means of block diagrams and each one of their components is analyzed in detail. This description is mainly focused on the Intermediate Frequency process since at this stage SDR makes its strong contributions. Additionally, implementation constraints are commented and finally, further works are identified.
