This paper reports on a study of hybrid optical/radio frequency (RF) architectures for deep space missions. Previous proposed optical deep space communication architectures were generally designed to achieve 90% or better availability 24/7. This study, instead, considered alternative metrics and architectures. It focuses on a strategy to use RF links and existing RF infrastructure for navigation and...
In order to reduce the operation cost of the deep space missions, a new autonomous navigation algorithm based on the observed images information of different celestial objects is proposed. First, it uses the directional data from the moon and the earth sensors to determine the initial orbit information of the explorer by geometrical method. Then combination with the observation from the star tracker,...
