Spacecraft Trajectory Planning for Optimal Observability using Angles-Only Navigation
… to develop optimal range observability maneuvers and trajectory planning methods for spacecraft under constrained relative motion. The resulting contribution is a guidance method for impulsive rendezvous and proximity operations valid for elliptic orbits of arbitrary eccentricity.</p> <p>The …

Developments for the Characterization of Spacecraft Proximity Operations for Improved Space Situational Awareness
… increasingly populated by numerous individuals and organizations, the capabilities of satellites on orbit have also improved. A variety of satellites are able to perform operations in close proximity to each other in order to complete a number of different missions. Maintaining awareness of …

A* Node Search and Nonlinear Optimization for Satellite Relative Motion Path Planning
The capability to perform rendezvous and proximity operations about space objects is central to the next generation of space situational awareness. The ability to diagnose and respond to spacecraft anomalies is often hampered by the lack of capability to perform inspection or testing on the target …

Integral Quadratic Constraints and Safety Certificates for Uncertainty Characterization and Control Safety-Aware Filtering of Proximity Operations Between Satellites
Techniques in robust optimization and formal verification methods are used (1) to examine the stability and robust performance of a satellite controller that considers six-dimensional, uncertain state, and often unmodeled dynamics during rendezvous and proximity operations, and (2) to explore the …

Rendezvous approach guidance for uncooperative tumbling satellites
The development of a Rendezvous and Proximity Operations (RPO) guidance algorithm for approaching uncooperative tumbling satellites has multiple purposes including on-orbit satellite servicing, space debris removal, asteroid mining, and on-orbit assembly. This thesis develops a guidance algorithm …

Angles-only navigation technique for maneuver-free spacecraft proximity operations
… the nominal angle profile between the surveyor and the target. In the space environment, the orbital dynamics are inherently nonlinear and natural orbit perturbations have the effect of continuous micro-maneuvers. These advantageous conditions present an opportunity to overcome the ambiguity …
