OTIS4 is used to support actual launches at the NASA Kennedy Space Center. The OTIS4 results compare extremely well to those of the legacy codes used by the Launch Vehicle providers to generate their final ‘as-will-be-flown-tomorrow’ trajectories. State vector comparisons in various frames such as Body Inertial, EME 2000, Flight Path, and Orbtial elements, all compare well. Detailed trajectory plots also show good comparisons of a wide range of trajectory/mission/vehicle parameters, including steering profiles.
