Описание:
Provides technical and scientific descriptions of potential approaches used to achieve indoor positioning, ranging from sensor networks to more advanced radio-based systems
This book presents a large technical overview of various approaches to achieve indoor positioning. These approaches cover those based on sensors, cameras, satellites, and other radio-based methods. The book also discusses the simplification of certain implementations, describing ways for the reader to design solutions that respect specifications and follow established techniques. Descriptions of the main techniques used for positioning, including angle measurement, distance measurements, Doppler measurements, and inertial measurements are also given.
Indoor Positioning: Technologies and Performance starts with overviews of the first age of navigation, the link between time and space, the radio age, the first terrestrial positioning systems, and the era of artificial satellites. It then introduces readers to the subject of indoor positioning, as well as positioning techniques and their associated difficulties. Proximity technologies like bar codes, image recognition, Near Field Communication (NFC), and QR codes are covered--as are room restricted and building range technologies. The book examines wide area indoor positioning as well as world wide indoor technologies like High-Sensitivity and Assisted GNSS, and covers maps and mapping. It closes with the author's vision of the future in which the practice of indoor positioning is perfected across all technologies. This text:
Explores aspects of indoor positioning from both theoretical and practical points of view
Describes advantages and drawbacks of various approaches to positioning
Provides examples of design solutions that respect specifications of tested techniques
Covers infra-red sensors, lasers, Lidar, RFID, UWB, Bluetooth, Image SLAM, LiFi, WiFi, indoor GNSS, and more
Indoor Positioning is an ideal guide for technical engineers, industrial and application developers, and students studying wireless communications and signal processing.

Описание: In April of 1973, a memorandum issued by the Deputy Secretary of Defense consolidated two experimental satellite navigation programs into one effort: The NAVSTAR Global Positioning System was born. After 22 years and $8 billion dollars, the system was finally declared fully operational in 1995.
In 1983, a Reagan Administration directive authorized civilian use of the system. Evidence, however, shows that civil access to GPS was intended all along. Since the Reagan decision, the civil market has grown exponentially, and is predicted to exceed $8 billion in the year 2000. By 1995 alone, civil users outnumbered military users by ten to one.
While civil access is permitted, its users are subject to an intentionally degraded signal called "selective availability" that restricts accuracy to 100 meters. Civil users resent the degradation policy and have resorted to differential GPS techniques to evade the accuracy restrictions. Some commercial providers claim their subscription services allow accuracies close to 45 centimeters. The Department of Transportation is also in the differential GPS business, providing maritime and aviation augmentations. By Presidential decision, selective availability will be removed within ten years.
