ECTS - University of Pisa
The course gives an overview of current methods in mission analysis and design for space systems. The main ideas of dynamical systems and optimal control theories enabling derivation of non linear astrodynamics solutions are introduced. The general n-body dynamics are treated by decoupling the problem in simplified models spanning from the classical patched conic approach to perturbation techniques. Mainly, restricted three body models, with their inherent features, are presented together with optimization principles of non-Keplerian low thrust trajectories. Practical examples are discussed with reference to real mission applications.
The final exam aims at evaluating the student preparation on the topics covered by the lectures with specific reference to the following aspects: - knowledge acquisition; - critical understanding; - capability of using in a creative and constructive way the information from the course lectures to develop original solutions to an engineering problem. The student will be assessed on his/her demonstrated ability to: - illustrate the derivation from first principles of his/her solution to the given problem(s) by the introduction of the relevant simplifications and/or approximation; - justify the introduction of the simplifications and/or approximations used in the derivation; - assess and discuss the expected level of accuracy and limits of application of the proposed solution. The student must be able to illustrate the reading matter thoughtfully, clearly, synthetically, effectively and with propriety of expression.

Further information:
The final exam consist in an interview where the student will typically be required to: – develop in writing of the solution to an original problem addressable by using the information from the course lectures in a creative and constructive way; - illustrate orally or answer questions on one or more topics of the course. Both aspects will be weighted equally (50%).
