Satellite Sequencing Optimization Using A Genetic Algorithm, Andrew Verstraete
Research and Creative Activities Poster Day
The problem of mission design for a robotic servicing satellite in geosynchronous Earth orbit (GEO) was investigated. A representative set of potential client satellites was selected, and operational needs were randomly assigned based on the average number of GEO retirements, anomalies, and repositioning maneuvers that currently occur each year. An objective function was developed to represent the value of servicing mission sequences, including client fees, time penalties, and operational risk. A genetic algorithm was then used to find sequences of operations on the potential client set that maximized the objective function’s value. Scenarios were analyzed with the database of satellites …

Introduction
- The motivation for this project is the development and proposed use of novel nanoengineered polymeric materials in many industrial and commercial applications. This necessitated the development of a robust metallic coating that can withstand aggressive environmental conditions.
- This research explores the methods of electroplating nickel and copper to the substrate, including the effects of various duty cycles and cathode current density
