Rendezvous: Stories and a Novella
<p>People are often a product of their environment, and each of the characters in this collection is an example of that shaping effect. These stories take you to the southern plains–land of red dirt, Bluestem, and prairie wind. Themes like hope, loss, and the exploration of frontier appear …

Optimal cooperative power-limited rendezvous
Minimum-fuel rendezvous of two power-limited low-thrust spacecraft is investigated. Both vehicles are active and provide thrust to complete the rendezvous. Total propellant consumption is minimized. Two gravitational field models are investigated: the Clohessy-Wiltshire linearized field and the …

Optimal cooperative time-fixed impulsive rendezvous
… trajectories for the fixed-time cooperative rendezvous of two spacecraft. The method assumes that the vehicles perform a minimum of three impulsive maneuvers with each vehicle being active, that is, making at least one maneuver. The cost of a reference rendezvous solution is improved by an …

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 …

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 …

Fuel optimal rendezvous including a radial constraint
Fuel-optimal rendezvous in orbit is examined using thrust-impulses and coasting arcs. Necessary conditions for the optimality of fuel-optimal rendezvous with and without radial constraints are derived. These conditions are then used to verify the optimality of trajectories obtained from a …

Optimization of Active Rendezvous Trajectories by Genetic Algorithms
… UnderWater Vehicles (UWV) trajectories and rendezvous trajectories of continuous low-thrust spacecraft are examined. One of the methods to solve such problems is the Genetic Algorithm (GA) method. In this work, a GA has been developed using Matlab®. It treats possible solutions to the …

Cooperative Power-Limited Optimal Rendezvous Between Many Spacecraft
<p>The minimum fuel rendezvous problem between several power-limited low-thrust spacecraft neighboring either a circular or an elliptic orbit is investigated. Both cooperative and non cooperative maneuvers are studied. The maximum principle of Pontryagin is applied to the optimal control rendezvous …

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
… 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 the chase …

Six degree of freedom optimal trajectories for satellite rendezvous
… with no imposed constraint on the time of the rendezvous. Further solutions are then found by varying the vehicle center of gravity location along one axis, thereby coupling the rotational motions into two axes of translation thrusters, and by imposing time limits on the rendezvous. A …
