Estudo de Arquitetura de Comunicação para a Missão BiomeSat

This work presents a preliminary study of the communication architecture for the BiomeSat nano-satellite of the National Institute for Space Research (INPE). The project includes the provision of up to four onboard payloads, which requires an adequate dimensioning of the communication system, as well as simulations of the positioning of the antennas in consideration of the radioelectric mockup. Two configurations are presented considering the radiocommunications regulations and commercial options (COTS) available for the equipment employed to highlight the existing trade-offs among bandwidth efficiency, power, and complexity, in attending to the mission application requirements.
