Opis

Space Dynamics: An Introduction is a self-contained introductory textbook covering both orbital mechanics and spacecraft attitude dynamics. Each topic is covered in a rigorous and systematic manner. Practical applications are covered in detail using realistic space flight examples, and solved examples and exercises are also included. While the emphasis is on analytical derivation, numerical methods will also be covered for completeness. Space Dynamics: An Introduction contains answers to selected exercises and is accompanied by a website hosting supplementary material for instructors.
