Dynamic Ground-Track Chasing Constellation Using Atmospheric Drag

摘要

In this paper, we present an autonomous control system that enables satellites flying in formation to maintain their relative position by using atmospheric drag. The control system uses a simple model of the atmosphere and overcomes modelling errors by dynamically adapting the spacecraft ballistic coefficients according to the satellite feedback response. No propulsion system is required for formationkeeping. We show the control of 3 possible formations to demonstrate the performances of the proposed system.
