Pub229, Sight Reduction Tables for Marine Navigation PDF Author: NIMA Staff
Publisher: ProStar Publications
ISBN: 9781577851936
Category : Transportation
Languages : en
Pages : 402

Book Description
The Sight Reduction Tables for Marine Navigation (Pub 229) is published in six volumes, each of which contains two-eight degree zones of latitude with a one-degree overlap between volumes. They are designed to facilitate the practice of celestial navigation at sea. The tables are primarily used with the intercept method of sight reduction by entering arguments of latitude, declination, and local hour angle and obtaining tabulated altitudes and azimuth angles. The tables are prepared and published by NIMA on an as-needed basis.

Celestial Navigation

Celestial Navigation PDF Author: Dominique F. Prinet
Publisher: FriesenPress
ISBN: 1460242114
Category : Sports & Recreation
Languages : en
Pages : 120

Book Description
This manual has grown out of all the courses given by Dominique Prinet, a certified Instructor-Evaluator for Sail Canada who has been teaching celestial navigation since 2000. It has benefitted from the thoughtful contributions of over 100 students. The aim of Celestial Navigation is to give a sufficient grounding in the subject to determine position at sea using a sextant for fixes on the sun, moon, stars and planets. Furthermore, the material presented will prepare a reader who wishes to pursue a Celestial Navigation Certificate through self-study. The subject requires some comfort with the basic concepts of navigation, but the prospective navigator only needs to know how to add and subtract either times or angles. Lucid and well-paced, Celestial Navigation starts with fundamentals and definitions which ensure that a motivated student need not bring anything more to the table than his or her willingness to master the subject. Richly illustrated, it includes a chapter with more than forty pages of review exercises covering all topics. The cleverness of many of the concepts, explained here, will bring about great intellectual joy and satisfaction. Whether you are a recreational sailor or an individual pursuing professional certification as a navigator, Celestial Navigation will teach you what you need to know.

Celestial Navigation in the GPS Age

Celestial Navigation in the GPS Age PDF Author: John Karl
Publisher: Paradise Cay Publications
ISBN: 9780939837755
Category : Technology & Engineering
Languages : en
Pages : 292

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.

Coastal Navigation

Coastal Navigation PDF Author: Dominique F. Prinet
Publisher: FriesenPress
ISBN: 1525521233
Category : Transportation
Languages : en
Pages : 143

Book Description
Coastal Navigation for Class and Home Study is based on the notes prepared for students by the author during some 20 years of teaching navigation, initially to private or commercial pilots, and then to sailors and professional mariners. The book is copiously illustrated with graphics which explain chart projections, scales and symbols, and describe lights and other navigation aids. It demystifies the True, Magnetic and Compass Norths as well as problems of time, speed and distances, and explains how to plot courses and take bearings, or draw regular and advanced Lines of Position using the international system of labeling. The book further clarifies the use of vectors to easily determine the impact of a current on the boat speed and direction, and goes on to show how to evaluate tides and currents. The final sections describe the use of GPS and electronic charts, highlighting their limitations. Additional notes and explanations are given in the areas where students traditionally experience difficulties, as well as supplementary examples and exercises. The companion book, Coastal Navigation Exercises, offers all the exercises needed for practice.

100 Problems in Celestial Navigation

100 Problems in Celestial Navigation PDF Author: Leonard Gray
Publisher:
ISBN: 9780939837335
Category : Sports & Recreation
Languages : en
Pages : 166

Book Description
Traditional navigation with a sextant, an almanac, and a book of tables is still thriving, even with the availability of accurate, cheap GPS receivers. Batteries sometimes go dead, and electronic devices fail, especially in salt air. Also, it can be satisfying and fun to work out a position and plot it, all on your own - but getting good at it requires some practice.100 problems is a self-contained book of realistic celestial navigation problems, including excerpts of all the necessary Nautical Almanac pages and sight-reduction tables, with answers and explanations.

Hawaii by Sextant: An In-Depth Exercise in Celestial Navigation Using Real Sextant Sights and Logbook Entries

Hawaii by Sextant: An In-Depth Exercise in Celestial Navigation Using Real Sextant Sights and Logbook Entries PDF Author: David Burch
Publisher:
ISBN: 9780914025184
Category : Sports & Recreation
Languages : en
Pages : 176

Book Description
In the spirit of early Bowditch editions, we offer navigation details of a full ocean passage as an excellent way to learn the ropes of practical celestial navigation. With your own tables and plotting sheets, you can analyze 224 timed sextant sights of sun, moon, stars, and planets to obtain 26 position fi xes to fi nd your way along a 2,800-nmi voyage lasting 17 days. Solutions are provided by computation, workforms, and detailed plots using universal plotting sheets. After completing this passage you will be prepared to navigate by celestial navigation on your own, whether you need to or choose to. Also includes notes on optimizing sight analysis, hurricane tracking, DR error analysis, ocean currents, and use of visible light ranges for nighttime arrivals.

Radar and ARPA Manual

Radar and ARPA Manual PDF Author: A. G. Bole
Publisher: Elsevier
ISBN: 148310222X
Category : Technology & Engineering
Languages : en
Pages : 431

Book Description
Radar and ARPA Manual focuses on the theoretical and practical aspects of electronic navigation. The manual first discusses basic radar principles, including principles of range and bearing measurements and picture orientation and presentation. The text then looks at the operational principles of radar systems. Function of units; aerial, receiver, and display principles; transmitter principles; and sitting of units on board ships are discussed. The book also describes target detection, Automatic Radar Plotting Aids (ARPA), and operational controls of radar systems, and then discusses radar plotting. Errors associated with the true-motion presentation; accuracy and errors of manual plotting; radar plotting aids; and regulations for preventing collisions at seas as applied to radar and ARPA are described. The book also underscores the accuracy and errors of ARPA. The test scenarios; errors generated in the radar installation; classification of ARPA error sources; and errors in displayed data and interpretation are explained. The manual is a good source of information for readers wanting to study electronic navigation.
