Next generation satellite orbital control system
… architectures for the Next Generation Satellite Orbital Control System (NG-SOCS) are developed from compiled system specifications and a review of existing technologies. From the developed architectures, the recommended architecture is selected based on real-world considerations that face …

Coupled Attitude And Orbital Control System Using Spacecraft Simulators
… flying missions. This motion is coupled because orbital control is dependent on the spacecraft attitude for vectored thrust. Formation flying spacecraft have a limited mass and volume for propulsion systems. We want to maximize the efficiency of the spacecraft, which leads to minimizing the error …

Orbit control for a spacecraft around a splitting contact binary asteroid
This thesis examines an orbit control problem for a spacecraft around a contact binary asteroid considering the dynamics of both the spacecraft and the asteroid itself. It is known that approximately 15\% of the near-Earth asteroids are binary, and among these the fraction of contact binaries is …

The design, fabrication and testing of micro-fabricated linear and planar colloid thruster arrays
New space applications such as orbital control of micro-satellites and precise interferometry have created a demand for high precision, low thrust efficient space engines. Electrospray propulsion is a serious candidate for this new technological niche. Electrospray thrusters are space propulsion …

On the dynamics, navigation and control of a spacecraft formation of solar concentrators in the proximity of an asteroid
… Two concepts, and the corresponding dynamics and control, are presented based on previous trade-off and optimisation studies. The first uses a paraboloidic reflector to concentrate the solar radiation onto a solar-pumped laser, which is then directed onto a specific spot on the NEO by a small …
