Mission Timeline Control Scheme • Jettison timing controls amount of aerocapture ΔV • Guidance algorithm: numerical predictor-corrector • Only atmospheric accelerometer measurements required • Monte Carlo results show robustness to uncertainties in entry FPA, atmosphere, and burns Trajectory Modeling • End-to-end simulation models vehicle trajectory and uncertainties • 3-DOF integration of atmospheric equations of motion • Key outputs: • Deceleration • Heat Rates • Orbit uncertainties
