Orbital & Launch Mechanics - Fundamentals

Share |


Technical Training Short On Site Course Quote Every maneuver in space is counterintuitive. Fly your rocketship into a 100-mile circular orbit. Put on the brakes and you will speed up! Mash down on the accelerator and you will slow down! Throw a banana peel out the window and 45 minutes later it will come back and slap you in the face! In this comprehensive 4-day short course, Mr. Logsdon uses 400 clever color graphics to clarify these and a dozen other puzzling mysteries associated with spacecraft maneuvers. He also provides you with a few simple one-page derivations using real-world inputs to illustrate the concepts under study. View course sampler slides



For more than 30 years, Thomas S. Logsdon has conducted broadranging studies on boost trajectories and astrodynamics at McDonnell Douglas, Boeing Aerospace, and Rockwell International. His research projects have included Project Apollo, the Skylab capsule, the nuclear flight state and the GPS radionavigation system.

Mr. Logsdon has taught 300 short courses and lectured in 31 different countries on six continents. He has written 40 technical papers and 34 technical books, including Orbital Mechanics, Striking It Rich in Space, Understanding the Navstar, and Mobile Communication Satellites.

What You Will Learn:

  • How do we launch satellites into orbit and maneuver them to new locations?
  • How do today’s designers fashion performance-optimal constellations of satellites swarming the sky?
  • How do planetary swingby maneuvers provide such amazing gains in performance?
  • How can we design the best multi-stage rocket for a particular mission?
  • What are libration point orbits? Were they really discovered in 1772?
  • What are JPL’s superhighways in space? How were they discovered? How are they revolutionizing the exploration of space?

Course Outline:

  1. The Essence of Astrodynamics. Kepler’s amazing laws. Newton’s clever generalizations. Launch azimuths and ground-trace geometry. Orbital perturbations.
  2. Gliding into Orbit. Isaac Newton’s vis viva equation. Gravity wells. The six classical Keplerian orbital elements.
