Um Enfoque Probabilístico para a Avaliação do Ambiente Interferente Envolvendo Satélite Geoestacionário

Abstract

This paper proposes a probabilistic new approach to satellite interference analysis for the assessment of the geostationary-satellite orbit utilization. The analysis allows for the evaluation of the potential of any given orbital position in terms of both the need for and the difficulty of network coordination (bilateral negotiation aiming at the solution of eventual interference problems). Appropriate metrics, that reflect both aspects of the coordination process (need and expected difficulty) are defined and used in the proposed methodology. The probabilistic approach provides an effective evaluation of the GSO use and requires much less computer effort than those required by usual deterministic approaches. Numerical examples involving practical situations are presented and discussed.
