From the Bronze Age mariners of the Mediterranean to contemporary sailors using satellite-based technologies, the history of navigation at sea, the art of finding a position and setting a course, is fascinating. The scientific and technological developments that have enabled accurate measurements of position were central to exploration, trade, and the opening up of new continents, and the resulting journeys taken under their influence have had a profound influence on world history.

In this Very Short Introduction Jim Bennett looks at the history of navigation, starting with the distinctive cultures of navigation that are defined geographically - the Mediterranean Sea, and the Pacific, Indian, and Atlantic Oceans. He shows how the adoption of mathematical methods, the use of instruments, the writing of textbooks and the publication of charts all combined to create a more standardised practice. Methods such as longitude-finding by chronometer and lunar distance were complemented by the routine business of recording courses and reckoning position 'by account'. Bennett also introduces the incredible array of instruments relied on by sailors, from astrolabes, sextants, and chronometers, to our more modern radio receivers, electronic equipment, and charts, and highlights the crucial role played by the individual qualities of endeavour and resourcefulness from mathematicians, scientists, and seamen in finding their way at sea. The story of navigation combines the societal, the technical, and the human, and it was vital for shaping the modern world.

Institutional Reform Of Air Navigation Service Providers

Institutional Reform of Air Navigation Service Providers deals with the changes that have taken place in this major, technologically progressive industry as many countries moved away from direct provision by the government to forms of corporate or private provision. The author provides an up-to-date institutional and economic analysis of air navigation service providers' efforts to reform their governance and funding structures under these changes. The book discusses air navigation service providers in great detail, with a focus on the historical evolution of the industry's institutional and regulatory frameworks as well as the ongoing developments in the industry (e.g. the Single European Sky in Europe and NextGen in the US). The author departs from the more conventional quasi-descriptive analysis by performing economic and econometric analyses of the industry that explicitly include institutional variables, e.g. to explore whether the nature of ownership can be associated with different economic efficiency outcomes. The result is a rigorous assessment of the structures of various air navigation service providers, strengthened by the use of case studies and policy analysis of potential reform. The theme and scope of this book will appeal to anyone interested in the institutional and regulatory history of air navigation service providers, and its accessible approach will appeal to policy-makers and professionals as well as people who are interested, more broadly, in economic regulation.


Astronavigation 2017

This book acts as a manual for the ancient methods of navigating by the stars, which continue to provide the sailor or pilot with a timeless means of determining location. Despite the prevalence of GPS, a comprehensive set offormulae that can be evaluated on any inexpensive scientific calculator in the event of a catastrophic software or systems failure is a vital failsafe. It also serves as a living link to centuries of explorers from centuries past.

Beginning with the basics ofpositional astronomy, this guide moves on to the more complex math necessary to understand the ephemerides, tables showing the future positions of the stars and planets. These astronomical almanacs were the satellite navigation of their day. The objective of this book is twofold: to provide the reader with a concise, comprehensible manual on positional astronomy as it appliesto astro-navigation and to furnish the concise algorithms for findingthe position of the Sun and various navigational stars at any given instant.

In a world where too many mariners and aeronauts rely solely on technology and are vulnerable to solar flares, electrical issues, and the like, this knowledge can be a life-saving backup, not to mention a fascinating study in its own rights. Included is an exact mathematical way to determine your position inthe air or on the sea far more quickly and accurately than by using the old celestialnavigational method, without evenneeding to know or understand the underlying mathematics. Thereis even a section that teaches how to measure the azimuth of a star usingan analog wrist watch so if a sextant gets damaged, locating position is still possible. This book offers mathematicians and adventurers a way to determine position when the skies go dark.

The U.S. Navy has recently realized that their electronic navigation systems are vulnerable to cyberattack, and as a result has instructed the Naval Academy to begin teaching celestial navigation again.
