ASTOS, a reconfigurable software for design of mega constellations, operation of flying laptop and end-of-life disposal

Abstract

ASTOS (Analysis, Simulation and Trajectory Optimization software for Space applications) allows the user to set up arbitrary space scenarios with multiple vehicles. The versatility and reconfigurable capability of ASTOS enables its application during all the mission phases: from feasibility to end-of-life disposal. The paper presents the capabilities of ASTOS modelling mega constellations like OneWeb, supporting the operations of the Flying Laptop small satellites from the University of Stuttgart (DE) and the re-entry of the European Automated Transfer Vehicle (ATV).
