Autonomous orbital rendezvous using angles-only navigation
This study assesses navigation performance for rendezvous and close approach applications where on-board navigation must be accomplished through the use of angles-only measurements by developing various relative motion orbital trajectories. Chaser vehicle maneuvers designed to enhance the …

Orbital rendezvous using an Augmented Lambert Guidance scheme
The development of an Augmented Lambert Guidance Algorithm that matches the position and velocity of an orbiting target spacecraft is presented in this thesis. The Augmented Lambert Guidance Algorithm manipulates the inputs given to a preexisting Lambert guidance algorithm to control the boost of a …

Planning and scheduling proximity operations for autonomous orbital rendezvous
… operations scheduling problem for autonomous orbital rendezvous. The algorithm of this thesis allows the operator to specify planned modes, which encode the chase satellite's operations. The scheduler optimally places these modes in the midst of the environmental conditions that fall out of …

Optimal, impulsive, time-fixed orbital rendezvous and interception with path constraints
… solutions are obtained for the problem of orbital rendezvous and interception with path constraints. The coplanar case and a restricted class of path constraints are analyzed. A theory based on the extended problem of Bolza in the calculus of variations has been established to determine …

A Monte-Carlo performance analysis of Kalman filter and targeting algorithms for autonomous orbital rendezvous
Autonomous orbital rendezvous with an orbiting sample (OS) is seen as an enabling technology for a Mars Sample Return (MSR) mission, so several demonstrations have been planned. With CNES cooperation a proposed rendezvous demonstration was governed by ITAR restrictions, and a guidance and …

Orbital Debris Removal Technologies: A Hybrid Electrodynamic Tether and Ion Beam Shepherd Satellite Design for Fuel Efficient Contactless Debris Removal
… for the EDT is outlined which is used for orbital rendezvous with debris. Results show that a hybrid technology between EDT and IBS far outperforms the individual technologies of similar mass as it utilizes the strengths of both in order to overcome each of their weaknesses. Furthermore, …

Autonomous Visual Servo Robotic Capture of Non-cooperative Target
… capture stage by robotic manipulators after the orbital rendezvous and proximity maneuver being completed. Two challenges have been identified and investigated in this stage: the dynamic estimation of the non-cooperative target and the autonomous visual servo robotic control. First, an integrated …

On-orbit inspection of a rotating object using a moving observer
Many objects in space such as orbital debris, defunct satellites, and natural objects are uncooperative, meaning that they are not equipped with working sensors or actuators. There are several reasons to want to visit these uncooperative space objects with an inspector satellite: to deorbit or …
