(3) Crew Activity Planning

The crew activity planning workstation combines all on-orbit activity requirements from the user community into a cohesive and detailed plan of all activities while the Orbiter is on orbit. Included in this plan is a detailed plan of all Orbiter attitude maneuvers and time of nominal occurrence.

(4) Measurement and Stimulus

The measurement and stimulus workstation ("MAST") receives the requirements from the flight design and Recon workstations, integrates them with a standard data base, and delivers flight-unique data tapes to various users.

(5) Flight Software

The flight software workstation incorporates the MAST data tapes and other flight-unique inputs into a standard Orbiter flight software base load and produces a flight-unique Orbiter flight software release ("MMU").

(6) Mission Control Center

The Mission Control Center ("MCC") must configure to support each flight (and simulation) using a flight-unique release. To do this, the MCC incorporates the flight-unique MAST data tapes, the flight design trajectory definition, the Orbiter flight software, and user ground display requirements into a base MCC release. This flight-unique MCC release is used for crew/flight controller integrated simulation training as well as for actual flight support.

(7) Shuttle Mission Simulator

The Shuttle Mission Simulator (SMS) incorporates the payload flight-unique model requirements, the flight software, and the MAST data tapes into a base SMS load and produces a flight-unique release. This SMS release is used for both crew and flight controller training. Crew-only training is known as "standalone," whereas training in which the crew in the simulator is linked to the flight controllers in the MCC is known as "integrated."

It should be noted that the delivery of standalone training capability is one key measure of the success of the reconfiguration process, since it is at the end of the process and is essential for a successful flight.
