The objective of this report is the description and discussion of the several positioning systems employing earth artificial satellite systems as proposed or under development. The subject has been developed against a background of terrestrial navigation systems, particularly those employing electromagneitc radiation. (Author).
Fifty years after Sputnik, artificial satellites have become indispensable monitors in many areas, such as economics, meteorology, telecommunications, navigation and remote sensing. The specific orbits are important for the proper functioning of the satellites. This book discusses the great variety of satellite orbits, both in shape (circular to highly elliptical) and properties (geostationary, Sun-synchronous, etc.). This volume starts with an introduction into geodesy. This is followed by a presentation of the fundamental equations of mechanics to explain and demonstrate the properties for all types of orbits. Numerous examples are included, obtained through IXION software developed by the...
This book is a compilation of chapters that discuss the most vital concepts in the field of satellite navigation or global navigation satellite systems. It explores all the important aspects of this field in the present day scenario. Satnav is the technology which uses satellites to provide particular locations. It uses time signals emitted by radio to determine the exact longitude and latitude of areas and also provide altitude of the same. It is used for geo-spatial positioning. It is applied in Global Positioning Systems (GPS) worldwide and is being used by many different countries for their military and security purposes. While understanding the long-term perspectives of the topics, the book makes an effort in highlighting their impact as a modern tool for the growth of the discipline. It presents the complex subject of satellite navigation in the most comprehensible and easy to understand language. This textbook is appropriate for those seeking detailed information in this area.
"This book explores the use of information technology in aviation. It also presents new information technology in education for aviation personal for using decision support systems, expert systems, and artificial intelligence systems"--
Every amateur astronomer - and many non-astronomers - will be familiar with seeing a "star" that shows that characteristic steady slide across the starry background of the sky. Artificial satellites can be seen any night, and some as bright as the planets. But how many of us can identify which satellites or spent launch vehicle casing we are seeing? Artificial Satellites and How to Observe Them describes all the different satellites that can be observed without optical aid, including of course the International Space Station and the many spy satellites operated by different nations. Richard Schmude looks at them in detail and describes how they can be observed by amateurs, how to recognize t...
This authoritative work brings you a timely, unified analysis of the various satellite navigation technologies, applications, and services in operation or development, and of the challenges that lie ahead in this rapidly evolving field. It describes the segments, signal characteristics, performance, and securities aspects of the GPS system, including the advances anticipated in the next-generation GPS-III, and brings you up to speed on the developing European GALILEO system and its innovative characteristics, services, and potential. A look at ground-based and satellite-based augmentation systems (GBAS and SBAS) highlights their performance-improving features and how these systems may serve as connection rings between GPS and future networks like GALILEO.
