Low-Thrust Assisted Angles-Only Navigation, Robert W. Gillis
Low-Thrust Assisted Angles-Only Navigation, Robert W. Gillis
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Tradition spacecraft proximity operations require large and expensive on-board sensors and significant ground support. Relative angle measurements can be obtained from small, simple, and inexpensive on-board sensors, but have not traditionally been used for proximity operation because of difficulty generating rang information. In this thesis it is shown that useful relative range data can be generated provided that the spacecraft is experiencing a small continuous thrust such as would be provided by a low-thrust propulsion system. In previous work range observability was shown with impulsive maneuvers. This thesis will expand this work to low-thrust spacecraft and will show how range …
