Modelling of satellite control thruster plumes
… Such thrusters are normally fired for attitude control. The prediction of such effects must be undertaken at the design stage of the vehicle.<br/>In this study, the modelling of such plumes was undertaken. The following prediction techniques were implemented into computer programmes: (a) the …

Model-based guidelines for user-centric satellite control software development
Three persistent common problems in satellite ground control software used by satellite controllers are obsolescence, lack of desired features and flexibilities, and endless software bug fixing. The obsolescence problem occurs when computer and ground equipment hardware become obsolete usually …

Achieving broad access to satellite control research with zero robotics
… in 2006, the SPHERES facility, including three satellites aboard the International Space Station (ISS), has demonstrated many future satellite technologies in a true microgravity environment and established a model for developing successful ISS payloads. In 2009, the Zero Robotics program began …

Dynamic programming applied to electromagnetic satellite actuation
… While much work has been done for EMFF control for large separation distances, little work has been done for close-proximity EMFF control, where the system dynamics are quite complex. Dynamic programming has been heavily used in the optimization world, but not on embedded systems. In …

Adaptive Control of VSCMGs for Satellite Attitude Tracking
… In order to achieve these requirements, new satellite control algorithms are required. Adaptive control offers a strong solution to the uncertainty problem. This thesis develops several adaptive control algorithms for satellites equipped with momentum management devices. Momentum management …

Dynamics and Control of Satellite Relative Motion: Designs and Applications
… proposes analytic tools for dynamics and control problems in the perspective of large-scale relative motion without perturbations. Specifically, we develop an exact and efficient analytic solution of satellite relative motion using a direct geometrical approach in spherical coordinates. …

Analyses of algorithm performance for an oversubscribed scheduling problem
… application, scheduling for the Air Force Satellite Control Network (AFSCN). AFSCN scheduling assigns access requests to specific time slots on antennas at ground stations. The application is oversubscribed: not all tasks can be accommodated given the available resources. As a special class …
