Understanding Satellite Navigation

This book explains the basic principles of satellite navigation technology with the bare minimum of mathematics and without complex equations. It helps you to conceptualize the underlying theory from first principles, building up your knowledge gradually using practical demonstrations and worked examples. A full range of MATLAB simulations is used to visualize concepts and solve problems, allowing you to see what happens to signals and systems with different configurations. Implementation and applications are discussed, along with some special topics such as Kalman Filter and Ionosphere. With this book you will learn: How a satellite navigation system works How to improve your efficiency when working with a satellite navigation system How to use MATLAB for simulation, helping to visualize concepts Various possible implementation approaches for the technologyThe most significant applications of satellite navigation systems Teaches the fundamentals of satellite navigation systems, using MATLAB as a visualization and problem solving tool Worked out numerical problems are provided to aid practical understanding On-line support provides MATLAB scripts for simulation exercises and MATLAB based solutions, standard algorithms, and PowerPoint slides

Based on the design theory and development experience of Beidou navigation satellite system (BDS), this book highlights the space segment and the related satellite technologies as well as satellite-ground integration design from the perspective of engineering. The satellite navigation technology in this book is divided into uplink and reception technology, broadcasting link technology, inter-satellite link technology, time-frequency system technology, navigation signal generation and assessment technology, navigation information management technology, autonomous operation technology of navigation satellite. In closing, the book introduces readers to the technological development status and trend of BDS and other GNSS, and propose the technologies of future development. Unlike most current books on this topic, which largely concentrate on principles, receiver design or applications, the book also features substantial information on the role of satellite system in the GNSS and the process of signal information flow, and each chapter not only studies on the theoretical function and main technologies, but also focuses on engineering development. Accordingly, readers will gain not only a better understanding of navigation satellite systems as a whole, but also of their main components and key technologies.

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.

The objective of this book is to provide you the reader a complete systems engineering treatment of GNSS. I am an expert with practical experience in GPS/GNSS design and similar areas that are addressed within the book. I provide a thorough, in-depth treatment of each topic. Within this and the rest of the series, updated information on GPS and GLONASS is presented. In particular, descriptions of new satellites, such as GPS III and GLONASS K2 and their respective signal sets (e.g., GPS III L1C and GLONASS L3OC), are included. In this book I provide in-depth technical descriptions of each emerging satellite navigation system: BeiDou, Galileo, QZSS, and NavIC. Dedicated chapters cover each system's constellation configuration, satellites, ground control system and user equipment. Detailed satellite signal characteristics are also provided. Recently, I've heard from many engineers that they learned how GPS receivers work from this title. In this title, the design is included, and treatment of receivers is updated and expanded in several important ways. New material has been added on important receiver components, such as antennas and front-end electronics. The increased complexity of multiconstellation, multifrequency receivers, which are rapidly becoming the norm today, is addressed in detail. Other added features of this title are the clear step-by-step design process and associated trades required to develop a GNSS receiver, depending on the specific receiver application. This subject will be of great value to those readers who need to understand these concepts, either for their own design tasks or to aid their satellite navigation system engineering knowledge. To round out the discussion of receivers, updated treatments of interference, ionospheric scintillation, and multipath are provided along with new material on blockage from foliage, terrain, and man-made structures. Now there has been major developments in GNSS augmentations, including differential GNSS (DGNSS) systems, Precise Point Positioning (PPP) techniques, and the use of external sensors/networks. The numerous deployed or planned satellite-based augmentation system (SBAS) networks are detailed, including WAAS, EGNOS, MSAS, GAGAN, and SDCM, as are groundbased differential systems used for various applications. The use of PPP techniques has greatly increased in recent years, and the treatment in this title has been expanded accordingly. Material addressing integration of GNSS with other sensors has been thoroughly revamped, as has the treatment of network assistance as needed to reflect the evolution from 2G/3G to 4G cellular systems that now rely on multiconstellation GNSS receiver engines. While this title has generally been written for the engineering/scientific community, one of the series is devoted to GNSS markets and applications. Marketing projections (and the challenge thereof) are enumerated and discussion of the major applications is provided. As in the other series, this book is structured such that a reader with a general science background can learn the basics of GNSS. The reader with a stronger engineering/scientific background will be able to delve deeper and benefit from the more in-depth technical material. It is this ramp-up of mathematical/technical complexity along with the treatment of key topics that enables this publication to serve as a student text as well as a reference source.

This thoroughly updated third edition of an Artech House bestseller brings together a team of leading experts providing a current and comprehensive treatment of global navigation satellite systems (GNSS) that readers won’t find in other resources.
