A Viable Orbital Debris Mitigation Mission using Active Debris Removal
… with a high rotation rate. A rendezvous and deorbit orbital analysis are conducted using both a low fidelity tool (for preliminary results) and a high fidelity tool (for more precise results). The rendezvous analysis is used to select a mission architecture that was composed of two different …

Feasibility of Microsatellite Active Debris Removal Systems
… Analysis of rendezvous, docking, control and deorbit mission requirements determined that the design of a grapple-and-tug system will be driven by sizing of the propellant required to deorbit the target vehicle. Further sensitivity analysis determined that target altitude and mass are critical …

RIDDS: Removal of Irregular Debris Using Double Nets
… space debris to slow down and capture it for deorbit. The target debris will be less than 6U in size and tumble. Capture occurs in two stages. First, an untethered net is launched to detumble the target. Then, a second tethered net is deployed for capture and deorbit. This thesis will focus on …

Design of the control systems operations for the Iridium satellite system
… when necessary, and coordinate launch and deorbit of the satellites. The approach used to code and modulate the telemetry processed by the ground stations is analyzed in order to develop support software for a recommended data network configuration used at the ground stations. A …

The Effect of the Solar Cycle on Satellite Orbital Lifetime
… They could be fined for violating the FCC deorbit limit of five years. This thesis quantifies the effect of launch or processing delays on satellite orbital lifetime based on their orbit altitude and vehicle parameters such as mass, cross sectional area, altitude, and bus size. In general, …

On-orbit inspection of a rotating object using a moving observer
… space objects with an inspector satellite: to deorbit or deflect dangerous debris; to inspect and/or repair defunct satellites; or to observe, sample, or extract resources from natural objects such as asteroids and comets. After performing orbital rendezvous with the target object, the first …
