October 1995 marked the fiftieth anniversary of Arthur C. Clarke's
famous article in Wireless World proposing the use of satellites
placed in geosynchronous orbit for worldwide communications relay.
The article proved prophetic, for it heralded the modern era of
telecommunications. Beginning in the early 1960s, several series of
satellites were launched into Earth's orbit; collectively they
transformed the latter twentieth century, creating a global village
of instantaneous communications. Previously, the ionosphere had
defined the limits of radio communication; today, by going beyond
the ionosphere, broadband telecommunication has entered a new age.
This book describes the first attempts to go beyond the ionosphere,
including both the earliest uses of the Moon as a passive, natural
relay satellite and Project Echo, the massive inflated satellite
off which Earth stations bounced radio signals, as well as
contemporary communications via active-repeater artificial moons in
orbit about the Earth. It analyzes both American and foreign
satellite communications, the histories of several satellite
communications companies, the roles of government agencies, and the
contribution of research laboratories. The book is a collection of
papers originally presented during an international symposium held
in Washington, D.C., at the time of the fiftieth anniversary of
Clarke's 1945 article. Contributions from historians and other
scholars from throughout the world present a stimulating analysis
of one of the most important global technologies at work today-and
how it originated and evolved.
