ASTOS is a Trajectory optimization and simulation tool for launch and re-entry missions, orbit transfers, design optimization and for re-entry safety assessments.
It solves Aerospace problems with a data driven interface and automatic initial guesses. Since 1989, the European Space Agency has developed, and improved this trajectory optimization environment to compute optimal trajectories for a variety of complex multi-phase Optimal control problems. ASTOS is being extensively used at ESA and aerospace industry community to calculate optimal launch and entry trajectories and was one of the tools used by ESA to assess the risk due to the ATV 'Jules Verne' re-entry. ASTOS is compatible with Windows, Linux and Mac OS platforms.
It is maintained and commercialized by ASTOS Solutions Gmbh for the European Space Agency.
