Abstract:

This thesis presents the implementation issues of an ion propulsion subsystem IPS on a geosynchronous communications satellite. As an example, Ultra High Frequency UHF Follow-On class satellite is selected for this study. The issues include 1 impact of integration of IPS with other subsystems, such as the electrical power subsystem to take care of the heavy demand of power requirements and location of the subsystem with least impact on attitude control and plume impingement on solar arrays, 2 environmental considerations- particulate contamination, electrostatic discharge ESD, and electromagnetic interference EMI, and finally risks and benefits. Ion propulsion offers significant advantages over chemical propulsion due to its high specific impulse and the advent of xenon thruster technology, multikilowatt spacecraft, and nickel-hydrogen Ni-H2 batteries with demonstrated high cycle life have combined to make the ion thruster attractive for North-South Station Keeping NSSK.
