Satellites are increasingly used for global communications, as well as for radio and television transmissions. With the growth of mobile communications, and of digital technology, the use of satellite systems is set to expand substantially and already all students of electronics or communications engineering must study the subject.This book steers a middle path between offering a basic understanding of the process of communication by satellite and the methodology used; and the extensive mathematical analysis normally adopted in similar texts. It presents the basic concepts, using as much mathematical content as is necessary to make the process understandable. The principles introduced are backed up by examples of actual applications showing how professional systems engineers have achieved the required system performance capabilities. The practical systems chosen are representative of modern day applications and comprise an international communications system, an international maritime system and a regional system.

This is the first book to cover the Global Marine Distress and Safety System (GDMSS) in a comprehensive and readable way. GDMSS is now being developed to provide a new global communications and locating network to alert search and rescue services, and all students of navigation or maritime technology, and practising navigation officers, will need to be trained in its use.This accessible reference textbook provides students and new radio operators with all the knowledge necessary for a complete understanding of GMDSS and its related systems.

Maritime navigation has rapidly developed since the publication of the last edition of the title with methods of global position fixing for shipping becoming standardized. As in the previous two editions, this edition will provide a sound basis for the understanding of modern navigation systems and brings the student or professional up-to-date with the latest developments in technology and the growing standardization of maritime navigation techniques.Developed with close scrutiny from the US Merchant Marine Academy and the major maritime navigation centres in the UK, out-dated techniques have been replaced by an expanded section on the now standard Navstar GPS systems and the Integrated Nav. In addition, a new chapter on the application of electronic charts will also be included, as well as problems at the end of each chapter with worked solutions.
