You need a Nautical Almanac to do celestial navigation. In today’s digital age, why buy a new book every year when you can buy a digital Nautical Almanac that provides 100 years of Nautical Almanacs (1960 - 2059) for less than half the price of a single year of the book. All data is formatted and organized exactly as you are used to seeing it in the official Nautical Almanacs published by USNO and HMNAO. Here are some things you can do with ezNA that you can’t do with your book: - Generate and use 100 years of Nautical Almanac pages for the years 1960 through 2059. - Easily go directly to the page you want without thumbing through pages. - Highlight the data you are looking for by touching the row and column headings on the page. - Zoom and pan to clearly read the tables. - Using Zoom, pan, and highlight makes the almanac easy to use on a phone as well as a tablet. - Functions are provided to do the necessary table lookups to perform basic Cel Nav activities. - The function pages show all almanac values used in the function with an almanac icon. - Click or touch the icon to go to the correct page with that value highlighted. The concise sight reduction tables are included and the sight reduction function demonstrates how to use them. If you have never used them then you are in for a big surprise. They are amazing! In the format I am generating them, they are a total of 16 pages (32 pages in the official Nautical Almanac). With this few pages and a few extra steps to use them you can still generate sight reductions that are typically within about 1 NM of those produced by Pub 229. Pub 229 has about 400 pages per volume and there is a total of 6 Volumes! ezNA performs all astronomical calculations using the NOVAS 3.1 software from the US Naval Observatory (USNO) and a JPL ephemeris that covers the years 1960 through 2059. Since all calculations are performed in the app, ezNA is fully functional with no dependency on a data connection. Please note that this digital Nautical Almanac is already included in ezAlmanacOne, which is our full celestial navigation solution. There is no need to purchase ezNA if you already have ezAlmanacOne. ezNA is NOT a full celestial navigation solution. It is a digital Nautical Almanac with functions to support using the Nautical Almanac tables. You can only do a single full sight reduction at a time. Using ezNA and manually recording and plotting your reductions you can still generate a fix manually! ## Key features - 100 years of almanac data (1960-2059) - Instant page access - Data highlighting - Zoom and pan functionality - Offline astronomical calculations - Concise sight reduction tables ## Chart rankings - #177 in Top Paid · Navigation (US App Store) ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/ez-nautical-almanac/id6468887411/reviews.md ### 5/5 — Great Program *2025-01-27* I’ve been doing celestial navigation for 3 1/2 years now and I’ve used his annual nautical almanac every year. I bought then for $10 and I love them. A month ago I bought this program and it’s so easy to use. If I head out to sea I’m able to print up the pages that I need for the time I’ll be gone. I might even make it back up copy and keep it in someplace very very dry. If you are new to celestial navigation and want to practice but don’t have a horizon you could build a celestial navigation platform and on three adjustable bolts you can set up a mirror. Level up with an accurate level and then when you use the stars at night you’re able to adjust it even more to a great fine-tuning. During the day you can flip the mirror upside down and slowly pour water on it and you get about a 16th of an inch water mirror which works very very accurately. I’ve taken literally thousands of shots at the sun moon stars and planets. The moon for me still is a bit sketchy but the stars planets and sun have given me a lot of joy since June of 2021. The guy who put this together did great job. Christopher Cody ## Frequently asked questions about EZ Nautical Almanac ### What is EZ Nautical Almanac?
