Fundamentals of Orbital & Launch Mechanics Summary Award-winning rocket scientist Thomas S. Logsdon has carefully tailored this comprehensive 4-day short course to serve the needs of those military, aerospace, and defense-industry professionals who must understand, design, and manage today’s increasingly complicated and demanding aerospace missions. Each topic is illustrated with one-page mathematical derivations and numerical examples that use actual published inputs from real-world rockets, satellites, and spacecraft missions. The lessons help you lay out performance-optimal missions in concert with your professional colleagues. Instructor For more than 30 years, Thomas S. Logsdon, has worked on the Navstar GPS and other related technologies at the Naval Ordinance Laboratory, McDonnell Douglas, Lockheed Martin, Boeing Aerospace, and Rockwell International. His research projects and consulting assignments have included the Transit Navigation Satellites, The Tartar and Talos shipboard missiles, and the Navstar GPS. In addition, he has helped put astronauts on the moon and guide their colleagues on rendezvous missions headed toward the Skylab capsule, and helped fly space probes to the nearby planets. Some of his more challenging assignments have included trajectory optimization, constellation design, booster rocket performance enhancement, spacecraft survivability, differential navigation and booster rocket guidance using the GPS signals. Tom Logsdon has taught short courses and lectured in 31 different countries. He has written and published 40 technical papers and journal articles, a dozen of which have dealt with military and civilian radionavigation techniques. He is also the author of 29 technical books on a variety of mathematical, engineering and scientific subjects. These include Understanding the Navstar, Orbital Mechanics: Theory and Applications, Mobile Communication Satellites, and The Navstar Global Positioning System.

GPS Technology GPS Solutions for Military, Civilian & Aerospace Applications Each student will receive a free GPS Navigator! Summary In this popular four-day short course, GPS expert Tom Logsdon will describe in detail how precise radionavigation systems work and review the many practical benefits they provide to military and civilian users in space and around the globe. Through practical demonstration you will learn how a GPS receiver works, how to operate it in various situations, and how to interpret the positioning solutions it provides. Each topic includes practical derivations and realworld examples using published inputs from the literature and from the instructors personal and professional experiences. "The presenter was very energetic and truly passionate about the material" " Tom Logsdon is the best teacher I have ever had. His knowledge is excellent. He is a 10!" "The instructor displayed awesome knowledge of the GPS and space technology…very knowledgeable instructor. Spoke clearly…Good teaching style. Encouraged questions and discussion." "Mr. Logsdon did a bang-up job explaining and deriving the theories of special/general relativity–and how they are associated with the GPS navigation solutions."
