Summary

An astonishing total of 128 radio navigation satellites will soon be in orbiting along the space frontier. They will be owned and operated by six different sovereign nations hoping to capitalize on the financial success of the GPS constellation. In this four-day short course,Tom Logsdon describes in detail how these various international navigation systems work and reviews the many practical benefits they are providing to civilian and militar users scattered around the globe. Logsdon will explain how each radionavigation system works and how you can use it in practical situations.

"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!"

"Mr. Logsdon did a bang-up job explaining and deriving the theories of special/general relativity - and how they are associated with today's navigation solutions."

"I loved his one-page mathematical derivations and the important points they illustrate."

Instructor

Tom Logsdon has worked on radionavigation satellites and their constellations for more than 20 years. He helped design the Transit Navigation System and the GPS and he acted as a consultant to the European Galileo Spaceborne Navigation System. His key assignments have included constellation design, military and civilian applications, survivability enhancements and spacecraft autonomy studies.

Over the past 30 years Logsdon has taught more than 300 short courses in 31 different countries scattered across six continents. He has also made two dozen television appearances, helped design an exhibit for the Smithsonian Institution, and written and published 1.8 million words, including 34 non-fiction books. These include Understanding the Navstar, Orbital Mechanics, and The Navstar Global Positioning System.
