    Work Experience:

     

    2008 – 2012  : Comtech AeroAstro, Littleton, CO

                Modeling and Simulations / Principal Systems Engineer

     

    • Mission Analysis: Responsible for design, analysis and performance evaluation of various small satellite systems.  Used STK/Matlab to perform various parametric trade studies, analyze orbital events and optimize vehicle design configurations to support proposal and design efforts. Typical examples:

     

    • Satellite eclipse, beta-angle analysis, and solar angles of incidence
    • Optimal placement and orientation of star-trackers
    • Orbit maintenance, station-keeping maneuvers and propellant budgets
    • Orbital decay and de-orbit burn requirements
    • Constellation design with coverage and access requirements
