Complete almanac of Sun, Moon, planets, and 57 navigational stars
Comprehensive trip manager
Supports quick-sight reduction
Descripción del producto
Celestial is a complete package for celestial navigation on your Android device. It can perform celestial sight reductions, calculate fixes, present them visually, manage sights on multiple trips and assist in sight planning. It also includes a complete Almanac of the Sun, Moon, planets and stars. All this for less than the price of the Nautical Almanac for a single year!
In detail: - Supports quick sight reduction. Enter all sight values to quickly calculate an intercept or to double-check your own manual sight reduction. - Includes a comprehensive trip manager that allows you to manage sights taken during a trip. Keep your sights with you forever! - Multiple sights can be grouped and averaged together and a fix can be calculated. Lines of Position (LOP's) and fixes can be plotted on a virtual plotting sheet. - Running fixes are supported! - Includes a star finder and times of rise/set phenomena. Plan your sights and be on deck when it is time. - Includes the complete Almanac of the Sun, Moon, planets, 57 navigational stars, Aries and Polaris for the years 1980-2099. - Context-sensitive screen help for every screen so you always know what the intended function of the software is.
All sight reduction algorithms are based on the algorithms described in the Nautical Almanac (Sight Reduction Procedures). Celestial object positions are predicted using software from the US Naval Observatory.

1,0 de 5 estrellasUnusable when out at sea thanks to Amazon DRM

If not for one fatal flaw, I'd give this app five stars. Because of that flaw however, I must give it only one star.
I liked the software very much when I was practicing with it at home after buying it. However when I got out on the ocean and was taking sextant sights for real... when I most needed the app to work for me... my Kindle refused to run the app! When I tried to open the software on the Kindle all I got was an error message saying that an internet connection was required. I kid you not. A software package that is designed and marketed for used out on the ocean wouldn't work when I was out on the ocean because the Kindle wouldn't open the app without a WiFi connection and of course there's no WiFi available out on the ocean. How ridiculous can things get?
In defense of the Navimatics folks I should say that they were very helpful in tracking down the problem (after I got back to port without the help of their app). Their customer support team deserves a five star review. It turns out that it's not Navimatics's fault that their app didn't work without WiFi. It's Amazon's fault. Amazon reportedly requires an internet connection every few weeks in order to verify that all your apps are legally purchased. They call it "Digital Rights Management" (DRM). If your Kindle can't talk to the Amazon "mothership" periodically then the Kindle locks you out from using the apps.
I hope that all of you will join me in demanding that Amazon change their absurd DRM policy for this app on the Kindle. A celestial navigation program that doesn't work when you're out of range of WiFi is totally unusable.
Please Note: Navimatics has versions of this app that run on the i-phone, i-pad, or non-Kindle Android devices. So if you have one of those devices buy this app for that other device. Just don't buy it for the Kindle.

This is one of the clunkier apps I have tried to use. Navigation through it is not always intuitive, and sometimes it just doesn't help very much. I wanted something that would be like a celestial almanac because I dabble in astronomy. I don't know if I read the description wrong before I bought this or it just doesn't deliver.
