ENHANCEMENTS TO THE ASTRODYNAMICS SOFTWARE AND SCIENCE ENABLING TOOLKIT (ASSET)

The Astrodynamics Software and Science Enabling Toolkit (ASSET) is a free and opensource software library enabling rapid spacecraft mission design and analysis. The software is a parallel, object-oriented C++ library, with a Python front-end for quick development, and ease-of-use. ASSET is being developed at the University of Alabama’s Astrodynamics and Space Research Laboratory (ASRL) and is funded by NASA. This paper outlines new enhancements added to ASSET since its initial release, including improved adaptive mesh refinement techniques for collocation based optimal control problems, and vectorized integration routines.
