Celestial Navigation in the GPS Age


Book Description

Many books on celestial navigation take shortcuts in explaining concepts; incorrect diagrams and discussion are often used for the sake of moving the student along quickly. This book tells the true story-and the whole story. It conveys celestial navigation concepts clearly and in the shortest possible time.It's tailored for navigation in the GPS age-a time of computers, calculators, and web resources. Although it covers all of the traditional methods of 'working a sight, ' the primary thrust is using the (under $10) scientific calculator. By using equations that you key into your calculator, this book guides you toward a better understanding of the concepts of celestial navigation.You will learn novel ways to plot lines of position, ways to check your sextant accurately by star sights, and how to tell what time it is from a moon sight. The many appendices are a treasure of references and explanations of abstract ideas. Celestial Navigation is a crucial skill for the offshore navigator to know, this book provides the shortest path to that knowledge.




The Flight Navigator Handbook


Book Description

The Flight Navigator Handbook provides information on all phases of air navigation and is a source of reference for everyone in the field, from navigators to navigator students. This handbook explains how to measure, chart the earth, and use flight instruments to solve basic navigation problems. It also contains data pertaining to flight publications, preflight planning, in-flight procedures, and low altitude navigation. Specific topics covered throughout the pages of this informational and helpful guide include: Reading maps, charts, and grids Dead reckoning Radio aid fixing and radio navigation Celestial concepts and special celestial techniques Computing altitude Pressure pattern navigation And much more! Additional information can also be found in the four included and up-to-date appendixes. This includes a listing of references and supporting information used in this publication; mathematical formulas to use as an aid in preflight and in-flight computations; chart and navigation symbols; and a Celestial Computation Sheet.

Beginning Spatial with SQL Server 2008


Book Description

Microsoft SQL Server 2008 introduces new geography and geometry spatial datatypes that enable the storage of structured data describing the shape and position of objects in space. This is an interesting and exciting new feature, with many potentially useful applications. Beginning Spatial with SQL Server 2008 covers everything you need to know to begin using these new spatial datatypes, and explains how to apply them in practical situations involving the spatial relationships of people, places, and things on the earth. All of the spatial concepts introduced are explained from the ground up, so you need not have any previous knowledge of working with spatial data. Every section is illustrated with code examples that you can use directly in SQL Server. All of the topics covered in this book apply to all versions of SQL Server 2008, including the freely available SQL Server 2008 Express. What you’ll learn Understand the fundamental concepts involved in working with spatial data, including spatial references and coordinate systems. Apply these concepts in the collection and storage of spatial data in SQL Server 2008, using the new geometry and geography field types. Create different types of spatial data objects—points, lines, and polygons—and use these to describe real–world objects. Learn how to analyze spatial data using a range of supported methods, and be aware of a number of different practical applications for these methods. Be shown how to integrate SQL Server with other tools, such as Microsoft Virtual Earth, to display a visual representation of spatial data. Know how to ensure the performance of spatially enabled databases by creating appropriate spatial indexes. Who this book is for SQL Server developers who wish to use spatial data in Microsoft SQL Server 2008.




Operational Terms and Graphics


Book Description

This manual is a dual-Service US Army and US Marine Corps publication introducing new terms and definitions and updating existing definitions as reflected in the latest editions of Army field manuals and Marine Corps doctrinal, warfighting, and reference publications. It complies with DOD Military Standard 2525.
