PPT-Satellite Safety and Circularizing Orbits:

A Study in Simplifying Models Anthony Ko Motivation Why this is important Despite popular belief a significant amount of satellites experience drag which causes them to fall to Earth and gain eccentricity . Such a satellite is used to study th e universe help forecast the weather transfer telephone calls over the oceans assist in the navigation of ships and aircraft monitor crops and other resources and support military act ivities Following are the fo Lecture 05.
