Telecommunication Satellite Technical Solutions For Geo-Localisation Of Interfering Sources: An Innovative Approach

The subject of the paper is on the technologies and solutions concerning the capability to implement geo-localisation or Direction of Arrival (DoA) definition of interfering sources at ground from single satellite. The stimulus in studying and implementing suitable technical solutions comes from commercial and institutional Satellite Communication (SATCOM) operators. In this context, indeed, the radio frequency interference phenomena are becoming very critical, drastically impacting on Operators revenues. On the other side, the technology growing in the SATCOMs is opening new perspectives for the future telecommunication market inducing the operators and, in general, the stakeholders to consider very seriously the impact of the Radio Frequency Interference (RFI) in order to stimulate the research of suitable and affective solutions to counteract them but taking into account the costs.The present paper provides an outlook on the technical solutions in surveying and defining an effective and convincing geo-localisation technique. The described activity has been focused on the survey of the state-of-the-art of the current techniques for the geo-localisation from satellites, proposing the theoretical principle of an effective solution to be used by a single satellite providing effective perfomences in line with the expectation of the SATCOM Operators.Some result on the laboratory implementation of the "idea" concludes the paper.
