Autonomous Navigation for Crewed Lunar Missions with DBAN
Presented at the 2020 IEEE Aerospace Conference in Big Sky, MT. With the recent push for a crewed Lunar mission to descend, land, and ascend from the Moon, there is a need for real-time position, velocity, and orientation knowledge of a Lunar spacecraft. Proposed approaches to achieve this include t...

Presented at the 2020 IEEE Aerospace Conference in Big Sky, MT. With the recent push for a crewed Lunar mission to descend, land, and ascend from the Moon, there is a need for real-time position, velocity, and orientation knowledge of a Lunar spacecraft.
