Summary
Several hundred privately owned satellites hurtling though space are currently pulling in revenues exceeding $300 billion per annum. And, over the past 30 years, those impressive revenues have been growing at an average compound rate of 17.5 percent each year. In this 4day short course, instructor Thomas S. Logsdon will use 400 fullcolor visuals jampacked with useful information to summarize the salient features of the two most important spaceage technologies making those handsome profits possible: commercial communication satellites and international GPSstyle radionavigation systems.
Using hard data from a variety of realworld sources, this gifted instructor will cover all the topics you will need to know to become a worldranking expert in these two rapidly emerging fields.
Instructor:
For more than 30 years, Thomas S. Logsdon has conducted broadranging studies on communication satellites, spaceborne radionavigation techniques, booster rocket design, and orbital mechanics at Douglas Aircraft, Boeing Aerospace, and at Rockwell International. He has also taught and lectured at more than two dozen toptier universities, including Berkeley, USC, Oxford, Johns Hopkins, Cal Tech, Hong Kong University and the technology universities at Sydney, Australia, and Barcelona, Spain.
In his spare time, Mr. Logsdon has taught 300 wellcrafted short courses on a variety of technical topics. He has also lectured, consulted, and acted as an expert witness in 31 countries sprinkled across six different continents. And he has written and published 40 technical papers, magazine features, journal articles together with 32 technical books, including Mobile Communication Satellites, The Navstar Global Positioning System, Orbital Mechanics: Ideas and Insights, Understanding the Navstar, and Striking It Rich in Space.
