Download or read book Multipath in Air Traffic Control Frequency Bands Volume I Classification of Multipath Effects of Multipath on Systems and Causes of Multipath written by Institute for Telecommunications Sciences (U.S.) Office of Telecommunications and published by . This book was released on 1974 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The handbook has collected theories and techniques which have one or more of the following qualities: It has been in frequent use by engineers; it has been shown to be accurate; it can be applied to a wide variety of problems; it offers an easily obtainable upper or lower bound. Most of the problems arising because of multipath cannot be solved or described precisely, but instead involve assumptions or approximations, the effects of which cannot be quantified. The responsibility for the decision on which approximation or assumption to use for a particular problem is with the reader. Since the handbook is directed toward air traffic control (ATC) frequencies, most of the material presented is oriented toward frequencies above VHF, and toward line-of-sight paths. Two special sections, one on Omega and one on Loran are included. No information on HF propagation or ionospheric scatter is included. Finally, selection of the material in this handbook has been heavily influenced by the systems presently used by the FAA.

Download or read book Position Navigation and Timing Technologies in the 21st Century written by Y. Jade Morton and published by John Wiley & Sons. This book was released on 2021-01-13 with total page 902 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covers the latest developments in PNT technologies, including integrated satellite navigation, sensor systems, and civil applications Featuring sixty-four chapters that are divided into six parts, this two-volume work provides comprehensive coverage of the state-of-the-art in satellite-based position, navigation, and timing (PNT) technologies and civilian applications. It also examines alternative navigation technologies based on other signals-of-opportunity and sensors and offers a comprehensive treatment on integrated PNT systems for consumer and commercial applications. Volume 1 of Position, Navigation, and Timing Technologies in the 21st Century: Integrated Satellite Navigation, Sensor Systems, and Civil Applications contains three parts and focuses on the satellite navigation systems, technologies, and engineering and scientific applications. It starts with a historical perspective of GPS development and other related PNT development. Current global and regional navigation satellite systems (GNSS and RNSS), their inter-operability, signal quality monitoring, satellite orbit and time synchronization, and ground- and satellite-based augmentation systems are examined. Recent progresses in satellite navigation receiver technologies and challenges for operations in multipath-rich urban environment, in handling spoofing and interference, and in ensuring PNT integrity are addressed. A section on satellite navigation for engineering and scientific applications finishes off the volume. Volume 2 of Position, Navigation, and Timing Technologies in the 21st Century: Integrated Satellite Navigation, Sensor Systems, and Civil Applications consists of three parts and addresses PNT using alternative signals and sensors and integrated PNT technologies for consumer and commercial applications. It looks at PNT using various radio signals-of-opportunity, atomic clock, optical, laser, magnetic field, celestial, MEMS and inertial sensors, as well as the concept of navigation from Low-Earth Orbiting (LEO) satellites. GNSS-INS integration, neuroscience of navigation, and animal navigation are also covered. The volume finishes off with a collection of work on contemporary PNT applications such as survey and mobile mapping, precision agriculture, wearable systems, automated driving, train control, commercial unmanned aircraft systems, aviation, and navigation in the unique Arctic environment. In addition, this text: Serves as a complete reference and handbook for professionals and students interested in the broad range of PNT subjects Includes chapters that focus on the latest developments in GNSS and other navigation sensors, techniques, and applications Illustrates interconnecting relationships between various types of technologies in order to assure more protected, tough, and accurate PNT Position, Navigation, and Timing Technologies in the 21st Century: Integrated Satellite Navigation, Sensor Systems, and Civil Applications will appeal to all industry professionals, researchers, and academics involved with the science, engineering, and applications of position, navigation, and timing technologies. pnt21book.com

Download or read book Isochronous Wireless Network for Real time Communication in Industrial Automation written by Henning Trsek and published by Springer. This book was released on 2016-02-26 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation proposes and investigates an isochronous wireless network for industrial control applications with guaranteed latencies and jitter. Based on a requirements analysis of real industrial applications and the characterisation of the wireless channel, the solution approach is developed. It consists of a TDMA-based medium access control, a dynamic resource allocation and the provision of a global time base for the wired and the wireless network. Due to the global time base, the solution approach allows a seamless and synchronous integration into existing wired Real-time Ethernet systems.
