dc.description.abstractThe feasibility of using a three axis control, momentum bias system with magnetic actuators for sun-oriented operations is explored. Relevant equations of motion are developed for a sun-oriented coordinate system and control laws are developed for: initial spacecraft capture after launch vehicle separation; reorientation from Earth-oriented to a sun-oriented operations mode; sun-oriented attitude control; and momentum wheel control. Simulationsdemonstratingthestabilityandtimeresponsivenessofthesystemareperformed. Sensornoiseinputtests are performed to investigate the systems susceptibility to imperfect conditions. Cross product of inertia effects are also input to test for system instability.en_US
dc.description.abstractThe purpose of this research is to determine the mission readiness impact that would result if the allowance levels of Trident HM&E On-Board-Repair-Parts were reduced by 5%, 10%, 15%, or 20%. The dollar value of the reduced inventories is calculated to estimate the potential cost savings to the Operations and Maintenance, Navy (OM&N) appropriation account. The study concludes that reducing Trident HM&E allowance levels up to 20% wouldhavenoimpactonmissionreadiness. Atthe20%inventoryreductionlevel, the procurement cost savings to the OM&N appropriation for one Trident submarine is estimated to be more than $500,000 per inventory cycle.en_US
