HispaSim: A web application for satellite link budget optimization and management

Adequate link budget tools are required by satellite operators to generate optimized transmission plans that satisfies customer diverse demands using transponder resources (power and bandwidth) efficiently. Satellite operator has to face with a number of communication scenarios depending on the service. These scenarios cover from forward links used for DTH (Direct-to-Home) to bidirectional networks where both forward and returns can share the transponder resources. Moreover, a transition from desktop implementations to web-based applications is a must for satellite link budget tools. In this contribution, we present a web-based application entitled HispaSim conceived for the analysis and optimization of satellite link budgets that incorporates administration of users and database. HispaSim application has been developed by the Grupo de Radiación of ETSIT-UPM (Escuela Técnica Superior de Ingenieros de Telecomunicación, Universidad Politécnica de Madrid) developed for Hispasat and GMV.
