Mobile Satellite Communications Handbook

With a Preface by noted satellite scientist Dr. Ahmad Ghais, the
Second Edition reflects the expanded user base for this technology
by updating information on historic, current, and planned
commercial and military satellite systems and by expanding sections
that explain the technology for non-technical professionals.

The book begins with an introduction to satellite communications
and goes on to provide an overview of the technologies involved in
mobile satellite communications, providing basic introductions to
RF Issues, power Issues, link issues and system issues. It
describes early commercial mobile satellite communications systems,
such as Marisat and Marecs and their military counterparts.

The book then discusses the full range of Inmarsat and other
current and planned geostationary, low earth orbiting and hybrid
mobile satellite systems from over a dozen countries and
companies. It is an essential guide for anyone seeking a
comprehensive understanding of this industry and military
tool.

• Revised edition will serve both technical and
  non-technical professionals who rely every day on mobile satellite
  communications

• Describes and explains historic, current, and planned
  civil, commercial, and military mobile satellite communication
  systems.

• First Edition charts and tables updated and expanded
  with current material for today's mobile satellite technology
