Terrain-Relative And Beacon-Relative Navigation For Lunar Powered Descent And Landing, Daniel Porter Christensen
Terrain-Relative And Beacon-Relative Navigation For Lunar Powered Descent And Landing, Daniel Porter Christensen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
As NASA prepares to return humans to the moon and establish a long-term presence on the surface, technologies must be developed to access previously unvisited terrain regardless of the condition. Among these technologies is a guidance, navigation and control (GNC) system capable of safely and precisely delivering a spacecraft, whether manned or robotic, to a predetermined landing area. This thesis presents detailed research of both terrain-relative navigation using a terrain-scanning instrument and beacon-relative radiometric navigation using beacons in lunar orbit or on the surface of the moon. The models for these sensors are developed along with a baseline sensor suite …
