On orbit satellite fuel consumption optimization with Analytic Hierarchy Process method

Abstract

Analysis of fuel consumption on orbit satellite is presented. The fuel consumption model is nonlinear based on the orbit thruster and attitude control thrusters' misalignment, and is assumed to have unknown dynamics. The issue regarding as the fuel consumption of orbit optimization can be converted to multi-variable optimization with constraint. A modification of the Analytic Hierarchy Process (AHP) optimization algorithm is introduced, by which the fuel consumption estimation models and judgment matrix are established. Simulation results are presented and the optimization design criterion for AHP is also put forward.
