Mission Planning & Operation Director (M-POD)

The goal of this initiative, funded by the Air Force and Wright-Patterson Air Force Base, was to develop a novel, radical approach for mission planning and operation that uses principles of dynamic inversion and constraint orthogonal polynomial basis (COPB) functions for solving a two-point boundary value problem for a non-flat (under-actuated) non-linear differential equation of motion.  The Mission Planning and Operation Director (M-POD) for Space Access Vehicles technology allowed mission planners to prepare a complete mission plan in a matter of hours instead of months.

The M-POD architecture was designed with an off-line component that defines and designs an optimal and nominal mission plan and an online component that assists in overcoming any off-nominal conditions resulting from trajectory reshaping and re-targeting.  Another important outcome of this effort was the advancement in technology for real time on-line trajectory solution under feasibility constraints.  The COPB functions facilitate implementation of boundary and in-flight constraints, and the dynamic inversion approach allows for the solving of a set of algebraic equations that strictly satisfy the non-linear differential equations of motion.  Our investigations demonstrated that a combination of dynamic inversion and smooth trajectory functional representation using COPB functions provides a powerful technique for the fast computation of feasible trajectories for a dynamic system.
