Description
In 2014, Thinking Systems began work on a parallel processing tool that incorporates the numerical engine from the General Mission Analysis Tool (GMAT) into a system, Paramat, designed to use the processing capabilities of modern, multi-core computer platforms. This paper opens with a brief description of recent changes to Paramat. Paramat is then used to model an orbital capture at Jupiter that uses gravity assists at Callisto, Io, and Ganymede to reduce the orbital insertion costs for the capture. That mission segment is presented as a baseline trajectory for Monte Carlo analysis of the costs of the insertion sequence. Perturbations are applied to the nominal capture trajectory and to parameters related to the course correction maneuvers in order evaluate the maneuver contingency costs for the capture. Analysis of these data provide insight into the total delta-V costs and margins for the capture phase of the mission, along with an estimate of the orbit determination requirements for each phase of the capture trajectory.
