The impact of precipitation on future next generation large NGSO satellite constellations is investigated in this contribution. To this aim, an advanced tool is used, which combines a model to generate realistic space-time correlated rain fields on a Global basis and a satellite orbit propagator for large constellations. The impact of rain attenuation on Q-/V-band links is investigated: the results indicate the need of Fade Mitigation Techniques for the correct operation of the system. Specifically, the benefits provided by the implementation of orbital and site diversity are assessed in terms of increased system availability for a given atmospheric fade margin.

Abstract
The impact of precipitation on future next generation large NGSO satellite constellations is investigated in this contribution. To this aim, an advanced tool is used, which combines a model to generate realistic space-time correlated rain fields on a Global basis and a satellite orbit propagator for large constellations. The impact of rain attenuation on Q-/V-band links is investigated: the results indicate the need of Fade Mitigation Techniques for the correct operation of the system. Specifically, the benefits provided by the implementation of orbital and site diversity are assessed in terms of increased system availability for a given atmospheric fade margin.| File | Dimensione | Formato | |
