Verification of a Micro-Thrusting Model to Maintain Satellites in Low Orbit.

Abstract

New concepts in aerospace travel have renewed interest in modeling and compensating for the effects of upper atmospheric drag. In particular, the SDI constellation requires strict orbital element maintenance. This thesis is a qualitative verification of a propellant longevity model for low-altitude earth orbit satellites verification of a propellant longevity model for low altitude earth orbit satellites doing intrack micro-thrusting to overcome atmospheric drag. Pertinent orbital mechanics and atmospheric concepts are reviewed. The model and its computer program are described. The results of trend and sensitivity analysis reasonableness tests are presented. Finally suggestions for use are made. Many plots of mission life predictions are presented. The model computer program and sample input and output are also included. Keywords: Low earth orbits; Drag compensation; Micro thrusting; Satellite orbital lifetime model; Propellent longevity; Orbital element design.
