Mahajan, Bharat (2018-05-08)In 1959, Dirk Brouwer pioneered the use of the Hamiltonian perturbation methods for constructing artificial satellite theories with effects due to nonspherical gravitational perturbations included. His solution specifically ...
-
Johnson, Kirk Wayne (2016-08-25)This dissertation explores new approaches for modeling perturbed and unperturbed satellite relative motion. It extends Hoots orbit theory, an analytical averaging-method perturbation solution to the Zonal Problem, to ...
-
Morris, Jeffery C. (2010-01-14)Automated spacecraft docking is a concept of operations with several important potential applications. One application that has received a great deal of attention recently is that of an automated docking capable unmanned ...
-
Satak, Neha (2013-05-06)The purpose of this dissertation is to apply behavior learning concepts to incomplete-information continuous time games. Realistic game scenarios are often incomplete-information games in which the players withhold ...
-
Fritz, Matthew Peyton (2011-02-22)Relative global positioning system (GPS) navigation is currently used for autonomous rendezvous and docking of two spacecraft as well as formation flying applications. GPS receivers deliver measurements to flight ...
-
Menon, Ramesh Gopal (Texas A&M University. Libraries, 1992)This dissertation presents a family of computationally efficient methods for the simulation of large, flexible multibody systems. Non-recursive order N formulations for the transient dynamic analysis of multibody systems ...
-
Kumar, Mrinal (2011-02-22)This dissertation addresses design and analysis aspects of stochastic dynamical systems using Fokker-Planck equation (FPE). A new numerical methodology based on the partition of unity meshless paradigm is developed to ...
-
Karimi, Reza (2012-07-16)A perfect duality exists between the problem of space-based orbit determination from line-of-sight measurements and the problem of designing an interplanetary autonomous navigation system. Mathematically, these two problems ...
-
Sovinsky, Michael Charles (Texas A&M University, 2007-04-25)The Poincare equations, also known as Lagrange's equations in quasi coordinates, are revisited with special attention focused on a diagonal form. The diagonal form stems from a special choice of quasi velocities that were ...
-
Sengupta, Prasenjit (Texas A&M University, 2007-04-25)The study of satellite relative motion has been of great historic interest, primarily due to its application to rendezvous, intercept, and docking maneuvers, between spacecraft in orbit about gravitational bodies, such as ...
-
Kim, Euisok (Texas A&M University. Libraries, 1993)The purpose of this research is to investigate the dynamics of a tethered satellite system in which the flexibility of the tether is considered and to design control laws for the deployment and retrieval of the tethered ...
-
Yan, Hui (Texas A&M University, 2006-10-30)In this dissertation the solutions of the dynamics and real-time optimal control of magnetic attitude control and formation flying systems are presented. In magnetic attitude control, magnetic actuators for the time-optimal ...
-
Weitz, Lesley Anne (Texas A&M University, 2005-11-01)Due to projectedincrea ses in air traffic, there are several research efforts underway to evaluate ways to safely increase the capacity of the National Airspace System (NAS), improve operational efficiency, andre duce ...
-
Wilkins, Matthew Paul (Texas A&M University, 2006-04-12)In this research, constellations of satellites all having orbits compatible with rotating reference frames are considered. That is to say, no matter how many satellites are considered for the constellation, when viewed ...
-
Sinclair, Andrew James (Texas A&M University, 2005-08-29)This dissertation addresses the generalization of rigid-body attitude kinematics, dynamics, and control to higher dimensions. A new result is developed that demonstrates the kinematic relationship between the angular ...
-
Park, Keun Joo (Texas A&M University, 2004-11-15)This dissertation explores both the estimation of various parameters from a multiple antenna GPS receiver, which is used as an attitude sensor, and attitude determination using GPS-like Pseudolite signals. To use a multiple ...

Gandhi, Varun R. (2010-07-14)The Electron Energy Corporation (EEC) along with the National Aeronautics and Space Administration (NASA) is researching magnetic bearings. The purpose of this research was to design and develop a high-temperature (1000�F) ...
-
McCrate, Christopher M. (2010-07-14)The solution of optimal control problems through the Hamilton-Jacobi-Bellman (HJB) equation offers guaranteed satisfaction of both the necessary and sufficient conditions for optimality. However, finding an exact solution ...
-
Bai, Xiaoli (2011-10-21)The solution of initial value problems (IVPs) provides the evolution of dynamic system state history for given initial conditions. Solving boundary value problems (BVPs) requires finding the system behavior where elements ...
