The Rubidium atomic clock (Rb) is the workhorse of the satellite navigation systems of which GPS is now a household name. With just the tap of a few keys, drivers and navigators all over the world are able to reach their destination effortlessly with high precision. People are now curious to know what makes this possible. Hence, the need to explain in simplistic terms the Rb atomic clocks that are onboard these satellite navigation systems because no good satellite navigation system is possible without such clocks.But why only Rb atomic clocks when far better and exotic atomic clocks are available? The reasons are as simple as that they are slim, low in weight, easy to build inexpensively. They are also used in numerous military applications such as secure communications, electronic warfare, command and control, telemetry and navigation. Besides, they are used in the measurements of the variation in fine-structure constant, test of relativity, precise spectroscopy and scientific research.This book details the history of time keeping and the chronological development of the Rb atomic clocks, with special focus on the physics Package that accounts for the actual performance of the clock. Researchers and industrialists will find that producing such clocks is relatively simple and inexpensive.

China is flexing its growing military and strategic clout in the pursuit of broadening national security interests. At the same time, the country’s economic and technology policies have also become more nationalistic, state-centered, and ambitious. China’s defense economy has set its sights on catching up with the West by the beginning of the 2020s and is making steady progress in building up its innovation capabilities, although this is presently in the form of incremental and sustaining types of activities. More high-end, disruptive forms of innovation that would lead to major breakthroughs are likely to be beyond China’s reach in the near-to medium term. This volume provides a wide-ranging and detailed assessment of the present state of the Chinese defense economy at a time of rapid change and accelerating advancement in its innovation capabilities and performance. This collection of articles has three main goals: (1) to locate China’s defense innovation dynamics within broader historical, technological and methodological frameworks of analysis; (2) to assess the performance of the Chinese defense economy’s six principal subsectors; and (3) to compare China’s approach to defense industrialization with major counterparts in the Asia-Pacific region. This book was originally published as a special issue of the Journal of Strategic Studies.

A very realistic geopolitical thriller, with all the elements of hybrid warfare, that begins with a murder. In Beijing, the delayed 22nd Communist Party Congress offers an opportunity to the PLA. The elite power brokers and party elders are unable to agree the new leadership line-up. The political stand-off starts fueling international tension surrounding Taiwan and the Diaoyu Islands. The PLA, taking advantage of the situation, seeks to bring matters to a head and resolve the Taiwan, South China Sea and Diaoyu island disputes by force. Or is it that simple? The ambition and designs of China create opportunities for others. In Mexico City, a multi-billionaire uses the conflict to further his ambitions for Mexico. In a diplomatic initiative with echoes of the 1917 Zimmermann Telegram, China makes a move to ensure Mexican and wider Latin American support for China. The implications dawn on a shocked America. As China unleashes its accumulated reserves of financial, economic and diplomatic power, will the debt-burdened and divided United States be able to respond? Will China’s massive gold and foreign exchange reserves and its dominance in global trade and world GDP help it prevail? The US finds itself isolated in confronting China. The Pentagon's attempts to gain the upper hand display a hopeless misunderstanding of the nature of the challenge. As World War Three threatens, is conflict with China inevitable? The First Battle of the Philippine Sea was a decisive naval battle of World War II, which eliminated the Imperial Japanese Navy and decided the war. Will the Second Battle of the Philippine Sea be the decisive naval battle of World War III? In the tradition of all great naval battles both sides will try to inflict a strategic disaster on the other, while avoiding such a fate themselves. Will victory favor the aggressive leadership and battle plan of the Americans or the conservative battle plan of the Chinese? As the crisis deepens and war looms, both sides field their latest technological secrets, in an unseen war in space and the cyber-sphere, as each seeks the virtual high ground in this prescient technothriller. Will we witness a reordering of the international hierarchy - the yielding of global hegemony - as an old empire attempts to replace the new and reclaim its rightful position? Is this fictional account of a clash between the United States and China - that has the unsettling qualities of a techno thriller deploying real and recognizable technical, financial, and military developments discernible today - what we can expect in 2032?

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
