Historically-oriented studies of the arms race tend to focus on major weapons and ignore the associated subsystems. In this book, the authors consider one subsystem--the navigation instruments and land-based transmitters--of the submarine-launched ballistic missile (SLBM) system. Paying particular attention to the Loran-C and Omega navigational units, the authors are able to draw conclusions on the accuracy of submarine-launched missiles and the reliability of America's sea-based nuclear deterrent.

General conclusion of various sources from the non-Soviet literature and some practical data obtained as a result of observation of the operation of a 'LORAN-C' during the time period 1963-1965 are presented. In operation the pulse-phased system, by comparison with other systems, utilizes a more complicated method of transmission of long radio waves and more complicated shipboard equipment is necessary for obtaining a similar reading of the navigational data. This definitely makes it difficult to study the operation of the pulse-phased system. Therefore, the present work may help master the basic operating principles of the pulse-phased system and correctly evaluate the technical and navigational possibilities of the LORAN-C radio navigation system.

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

The Global Positioning System (GPS) is a satellite-based navigation system that was originally designed for the U.S. military. However, the number of civilian GPS users now exceeds the military users, and many commercial markets have emerged. This book identifies technical improvements that would enhance military, civilian, and commercial use of the GPS. Several technical improvements are recommended that could be made to enhance the overall system performance.

The Federal Aviation Administration (FAA) has accepted the Loran-C navigation system as a supplemental navigation aid for enroute use. Extension of Loran-C utilization to instrument approaches requires establishment of a process by which the current level of performance of the system is always known by the pilot. This system 'integrity' translates into confidence that, if the system is made available to the pilot, the guidance will be correct. Early in the consideration of Loran-C for instrument approaches, the Loran-C Planning Work-Group (LPW) was formed with membership from the FAA, the US Coast Guard, various state governments, aviation users, equipment manufacturers and technical experts. The group was hosted and co-chaired by the National Association of State Aviation Officials (NASAO). This forum was ideal for identification of system integrity issues and for finding the correct process for their resolution. Additionally, the Wild Goose Association (WGA), which is the international Loran-C technical and user forum, regularly brings together members of the FAA, Coast Guard, and the scientific community. Papers and discussions from WGA meetings have been helpful. Given here is a collection of the issues in which Ohio University became involved. Issues definition and resolution are included along with the recommendations in those areas where resolution is not yet complete. Lilley, Robert W. and Brooks, N. Kent Unspecified Center NAG1-816...

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.

This report describes an extensive evaluation of Loran-C for use by general aviation. Flight, ground, and antenna tests were done. Flight tests measured the accuracy and the ability to make approaches. Receiver reliability and susceptibility to atmospheric noise were also studied. Ground tests looked into grid stability and grid war page. Antenna tests were done to evaluate three antenna configurations -- ADF, vertical whip, and trailing wire antennas. The measured accuracy met FAA AC 90-45A requirements for all phases of flight. Loran-C was found to be satisfactory for approaches within AC 90-45A specifications. Reliability was 99.7%, the receiver was insensitive to atmospheric noise. The time difference grid was stable in the long run. Antenna tests showed the ADF and vertical whip antennas to be suitable for airborne use. It is concluded that Loran-C is suitable for navigation as an alternative to VHF RNAV. This navigation system is suitable for use in general aviation aircraft.
