摘要

Fielding smaller spacecraft able to perform the same tasks as larger predecessors is an on-going emphasis for the aerospace community. This is largely driven by high launch costs incurred on a per-mass basis. In addition to the desire for smaller spacecraft, there is a parallel course of emphasis to enable existing and future spacecraft to have longer operational lifetimes. Less frequent launches could reduce the long-term costs of maintaining a presence in space. One solution is to have a separate spacecraft that can rendezvous with and inspect, re-boost, or refuel target satellites. To minimize costs, this satellite should be as small as possible, yet still have capabilities of fulfilling the mission objectives. A critical aspect of an inspector satellite is the propulsion system utilized to move around in orbit to its target(s) and to perform the desired proximity operations upon arrival.; The initial step in the current research was to explore similar previous missions, with an eye on subsystems and practices used to directly enable rendezvous and proximity operations.
