Celestial Navigation Workshop Sept. 7 & 8
Sep 7, 2019 9:00 AM - Sep 8, 2019 4:00 PM
Strawbery Banke Museum
14 Hancock Street, Portsmouth, New Hampshire 03801, United States
In this concise, two-day practicum in the theory and practice of Celestial Navigation, the methods commonly utilized—primarily the sun, but also the moon, planets and stars—will be laid bare and made clear.
Sights of the sun will be taken (weather permitting) with a simple sextant provided for you to take home, and sight reduction and plotting the resulting Lines of Position will complete the process. You will leave with enough knowledge to enable you to take and reduce your own sights and to plot your charted position.
These methods have been developed over centuries to allow normal people without any particular mathematical background to become effective navigators. And they still work today! In simplest form the processes are completed by the use of look-up tables. We will cover all of that, but also offer insight into more sophisticated methods using hand calculators and computers.
The necessary materials will be provided for you to use and take home – a simple Davis sextant, a current almanac, sight reduction forms, plotting sheets, and a CD of the course materials. We ask that you bring along a pencil and eraser, perhaps a set of dividers and tablet of paper. Please also bring your interest and curiosity.
