Instructed by Bong Wie, Professor Emeritus of Aerospace Engineering at Iowa State University
- This course introduces the fundamental problems of classical astrodynamics, such as the two-body problem, Kepler’s problem, Lambert’s problem, and orbit perturbations
- This course will include astrodynamical application examples to enhance the learning experience: ballistic missile and lunar trajectories; orbital transfer, intercept, and rendezvous guidance problems; orbit analysis and simulation of LEO and GEO satellites; hypersonic entry guidance and counter hypersonics
- It will further explore the technically challenging problem of developing a space-based missile defense system (e.g. the Golden Dome).
- All students will receive an AIAA Certificate of Completion at the end of the course
LEARNING OBJECTIVES
- The fundamentals of classical orbital dynamics and modern computational astrodynamics
- The orbital transfer, intercept, and rendezvous guidance problems
- A variety of astrodynamical guidance laws required for the successful development of a space-based interceptor missile system (e.g. the Golden Dome).
KEY TOPICS
- Classical Two-Body Problem
- Kepler’s Problem and Its Solution via Universal Variables
- Lambert’s Problem and its Various Computational Solutions; Lambert Guidance
- Perturbed Orbit Simulations of LEO and GEO Satellites
- Clohessy-Wiltshir-Hill (CWH) Relative Equations of Motion

AUDIENCE
This course is intended
for aerospace GNC engineers and researchers, space mission designers, space
systems engineers, technical managers, and graduate students, who want to enhance
their basic understanding of orbital dynamics and astrodynamical guidance, especially
as applied to the technically challenging problem of designing a space-based
missile defense system (e.g. the Golden Dome). This introductory course focuses on the basic
physical concepts and mathematical tools required for the analysis and design
of advanced space missions and GNC systems of space-based intercept missiles.
