Draper Laboratory is seeking a highly-motivated Graduate-level summer student interested in the design of Guidance, Navigation, and Control (GN&C) algorithms and software for complex civilian or commercial space applications. The candidate will work in a team responsible for the development of simulation models and analysis tools to evaluate GN&C functionality and performance. Specific activities will include simulation development, stability analysis, guidance and control law development, navigation accuracy assessments, robustness analysis, and support of GN&C software development and testing. This task will also require the development and maintenance of high-fidelity, 6-Degree-of-Freedom (6-DOF) dynamic simulation models of the vehicle. The Graduate Intern will implement non-real-time simulations and perform simulation-based analysis to define GN&C system requirements and capabilities.
