SHEFEX is a DLR-led series of missions for scienti c experiments and reentry technology development. SHEFEX-2 was successfully launched from Norway (Andoya Rocket Range) in June 2012. To go on with the e ort to increase the technological level for real space missions, a new challenge in the next years with the development of SHEFEX-3 arises. SHEFEX-3, foreseen to be launched in 2016, will be more complex than SHEFEX-2 in virtue of the presence of a real guided re-entry phase, while for SHEFEX-2 an autonomous Guidance and Control phase was only partially foreseen. As a consequence, the mission will be ambitious, especially in the development of the GNC subsystem. DLR GNC Systems Department will be responsible for the development of Guidance and Navigation modules, while Control will be developed by Airbus Defense and Space, in cooperation with DLR. In this work the development of the nominal entry guidance, based on the use of PseudoSpectral Methods, is discussed. This feedforward control is then coupled with a Gain-Scheduled LQR tracking controller to reduce the error on the terminal points of the mission. Results show that the proposed approach meets the requirements on the physical constraints and the terminal states, satisfying at the same time the strong limitations coming from the need to have a highly-constrained angle of attack pro le.
