Learning Outcomes
The module imparts knowledge in the basics of space flight mechanics. Space system engineers need the knowledge of space flight
mechanics for different application areas in space mission design and analysis, and orbit and attitude control of a spacecraft. The
engineering applications of space flight mechanics include the design of satellite orbits and interplanetary trajectories, rocket ascent
trajectories, re-entry and landing concepts, rendezvous and docking maneuvers. Part of the outcome is the understanding of satellite orbit
disturbances, different types of orbits, the basic laws of celestial mechanics, and time and reference systems. Further, a focus is set on
introducing the programmatic aspects, thus developing the basic skills required to analyze and develop qualitative solutions for a real-life
problem in the relevant application areas.
After successful completion of this course, students will be able to
- describe the characteristics of orbits, time and reference systems,
- explain the laws of celestial mechanics applicable to undisturbed satellite orbits,
- model gravitational and non-gravitational forces acting on an orbiting spacecraft,
- explain the influence of gravitational and non-gravitational forces on an orbiting spacecraft ,
- apply perturbation theory to develop qualitative solutions for a real space mission analysis and design problem,
- calculate the ground tracks using the orbital elements for a given orbit,
- explain the principles of relative motion applicable to the field of formation flight, rendezvous and docking,
- calculate the parameters of impulsive orbit maneuvers (e.g. delta-V, transfer time, and orbital elements),
- explain the basics terminologies and concepts of spacecraft re-entry.
