Global Navigation Satellite Systems

4-Day Course

Summary

A thick swarm of radionavigation satellites – at least 128 of them! -- will soon be orbiting our home planet. They will be owned and operated by six different sovereign nations hoping to capitalize on the technical and financial success of America’s highly successful GPS. In this comprehensive fourday short course Tom Logsdon will describe in detail how these various international navigation systems work and he will review the many practical benefits they are providing to civilian and military users scattered around the globe. He will also describe the salient features of each navigation system, describe its signal structure, and explain how you can use it most effectively 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.
