Modern Celestial Navigation
April 25 - April 26
This is not your grandparents’ celestial navigation! This is a fast-paced introduction to celestial navigation from a 21st century perspective. In this hands-on two-day workshop, participants will learn how to adjust and use sextants available on the market today. We’ll learn streamlined calculations using a common handheld solar-powered calculator. This workshop is designed especially for yachtsmen and recreational boaters. If you’re dreaming about a trans-oceanic voyage or circumnavigation, in this workshop you’ll learn all the techniques to determine latitude and longitude anywhere on Earth using the Sun and the brighter stars.
Celestial navigation stands as the only autonomous backup to GPS and electronic navigation, and it is a tradition that connects us with maritime history. Weather permitting, class participants will have opportunities to experiment with sextant observations. We’ll also learn how to use the Sun and stars as a highly accurate compass, a technique valuable in near-shore waters as well as blue-water sailing. This is real navigation, celestial navigation for the 21st century, not just a class about navigation
- Basic addition/subtraction, good familiarity with latitude and longitude. Some familiarity with basic algebra, especially positive/negative numbers.
- Recommended for ages 18+, but students as young as age 13 are welcome.
- You’ll need to purchase the recommended scientific calculator for the class: the “Casio fx-260 Solar” (original or newer “II” model) – widely available for less than $10 at Staples, Walmart, and other stores.
The course is taught by Frank Reed, a gifted teacher and a recent guest “expert in celestial navigation” on Neil deGrasse Tyson’s Star Talk science show on The National Geographic Channel. For more information, please visit www.reednavigation.com.
