## Description

**Nautical Astronomy** is a comprehensive Chrome extension designed for enthusiasts and professionals interested in traditional celestial navigation techniques. Using the classic tools of astronavigation, it allows you to calculate Latitude and Time by observing celestial bodies like the Sun and the North Star (Polaris) with a sextant.

The extension supports multiple calculation methods including Latitude by Polaris, Noon sight, Sun's meridian sight, and more. Input data easily by tapping parameters such as Date, Time, Dead Reckoning (DR), and sextant sight data, then use the built-in calculator to get precise navigation solutions. The app simplifies complex astronomical navigation by doing all calculations internally while still letting you practice the classic methods.

Additional features include location setting through Google Maps or GPS, examples and manuals provided by the developer, and permissions management for location and storage for seamless use. Nautical Astronomy is perfect for those wishing to hone their astronavigation skills using modern technology as a training companion.
