Given the orbital parameters of a satellite equipped with a steerable antenna and the locations of two ground stations whose visibility circles are overlapped (e.g. Matera and Svalbard), the model is able to compute the time spent by the steering mechanism to repoint the dowlink antenna from the first to the second station.-Given the orbital parameters of a satellite equipped with a steerable antenna and the locations of two ground stations whose visibility circles are overlapped (e.g. Matera and Svalbard), the model is able to compute the time spent by the steering mechanism to repoint the dowlink antenna from the first to the second station.
