The spaceplane configuration and the guidance navigation control related mission aspects are described. The Hermes orbital flight controller functional and operational architecture is presented with special consideration of hierarchical and modular design aspects. The orbital phase of the Hermes mission consists of separation, free flight, rendezvous and servicing on the MTFF (Man Tended Free Flyer), de-orbiting and orbital reentry phase. The dynamic/kinematic response of the spaceplane due to control and disturbance torques and forces is measured by the sensors of the navigation system, which also provides estimates for the control variables. The current status of the Hermes orbital flight controller integrates a baseline architectural design, functional definition and low level control algorithms.
