Introduction to Orbital Mechanics

Learn The Basics of Elliptical Orbits

What is Orbital Mechanics?

Orbital Mechanics, also sometimes called Astrodynamics, covers the motion of orbiting bodies like satellites and space vehicles that move under the influence of gravity.

If you're looking for a course that applies material learned from Physics, Dynamics, Calculus, and more, this is the class for you! We'll start off by deriving the 2-body relative motion equation. Then we'll work our way through the derivations of the trajectory equation, Kepler's equation and more. Orbital elements will also be covered. The Numerical Analysis topics Newton's Method and the 4th order Runge Kutta method will be taught as well and used in the projects.

This course will focus on the most common type of orbit: the elliptical orbit. Although there are other types of orbits, the elliptical orbit provides a great entry into the world of orbital motion.

To enhance your learning, homework sets are provided. These problems will let you apply what you've learned in the lectures. Then, if you want more of a challenge, MATLAB projects are given that combine our Orbital Mechanics material with techniques from Numerical Analysis. Never had a Numerical Analysis course? No worries! We'll cover everything you need to know.

  • Relative 2-body equation

Teaching is my passion. As a University professor I have taught 1000's of students and watched them transform from freshmen into successful engineers. Unlike many STEM professors, I believe in teaching complex material in simple, easy-to-understand terms. I teach my courses in a way I wish I had been taught...no complicated theories and half-worked examples.

In addition to University experience, I also worked as an engineer for 8 years in industry at a well-known defense company. This experience enables me to focus in on topics that are actually applicable in the real world, not just textbook problems.

Who should enroll in this course?

  • Engineering students wanting to get a head start on an upcoming Orbital Mechanics course
  • Students currently taking Orbital Mechanics who need extra examples and explanations
  • Students and professionals who are wanting to apply their engineering knowledge to a new challenging subject

What do I need to know before starting?

The typical prerequisites for this class are Calculus, Differential Equations, and Dynamics. If you want to work on the projects, you should be familiar with MATLAB.

Is there a recommended textbook?

I, along with most students I've taught, really like the Orbital Mechanics for Engineering Students text by Howard Curtis. It covers many topics beyond what will be covered in this course and it is easy to follow. If you don't already have a textbook this one would be a great resource, although it is not required for this course.
