<abstract>
    Рассмотрена задача выбора оптимальных спутников глобальных навигационных спутниковых систем для обработки на малых космических аппаратах систем дистанционного зондирования морской поверхности. Показано, что бистатический коэффициент частоты Доплера является параметром, определяющим качество восстановления параметров ветра и течений. Предложены три критерия оптимизации геометрической конфигурации, позволяющие автоматизировать выбор спутников. Методика проиллюстрирована примерами выбора GPS, ГЛОНАСС и Galileo спутников согласно рекомендациям официального проекта CYGNSS. Алгоритм требует минимальных вычислительных затрат

    The paper considers the problem of selecting optimal global navigation satellite systems satellites for processing onboard small satellite for remote sensing of the sea surface. It is shown that the bistatic Doppler frequency coefficient is a parameter determining the quality of retrieving wind and current parameters. Three criteria for optimizing the geometric configuration are proposed, allowing to automate the selection of satellites. The methodology is illustrated with examples of selecting GPS, GLONASS and Galileo satellites in accordance with the recommendations of the official CYGNSS project. The algorithm requires minimal computational costs.
