"This book is by far the most comprehensive and orderly treatment of the subject. It is the work of experts with a wealth of both theoretical and practical experience with the subject and its connecting disciplines. It is an integral work... concepts and notation are at the same consistent level throughout the book. Quality of Service (QoS) is an absolutely critical part of any telecommunication services. This work fills a gap in the literature of what possibilities there are for satellites in providing global Internet services." Excerpted from the Foreword by Raymond L. Pickholtz, The George Washington University

Riccardo Giacconi Harvard/Smithsonian Center for Astrophysics The meeting of the High Energy Astrophysics Division of the American Astronomical Society, held in Cambridge, Massachusetts on January 28- 30, 1980, marks the coming of age of X-ray astronomy. In the 18 years since the discovery of the first extrasolar X-ray source, Sco X-l, the field has experienced an extremely rapid instrumentation development culminating with the launch on November 13, 1978 of the Einstein ObÂ servatory (HEAO-2) which first introduced the use of high resolution imaging telescopes to the study of galactic and extragalactic X-ray sources. The Einstein Observatory instruments can detect sources as faint as 10-7 Sco X-lor about 17 magnitudes fainter. The technological developments in the field have been paralleled by a host of new discoveries: in the early 1960's the detection of 9 "X-ray stars", objects 10 times more luminous in X-rays than the Sun and among the brightest stellar objects at all wavelengths; in the late 1960's and early 1970's the discovery of the nature of such systems which were identified as collapsed stars (neutron stars and black holes) in mass exchange binary systems, and the detection of the first few extragalactic sources.
