ezSights for iOS

Please check out www.ezCelestial.com for a full description of the application and in-app help pages. ezSights is a complete celestial navigation package for the iPhone, iPod touch and iPad. It provides simple interfaces for entering sight parameters, planning the navigational bodies to use and time of day to make the observations, and entering the observations made using a sextant. Then with the click of a button a fix is determined from the observations made. Features. Internally calculated Nautical Almanac values, valid through 2059. Performs all calculations with same algorithms used by the US Naval Observatory for the Nautical Almanac. Supports all navigational bodies currently referenced in the Nautical Almanac. Computes rise and set times for the sun and moon. Computes moon phase, HP, parallax and semi-diameter. Animated star map to aid in locating and identifying all navigational bodies. Display of full day, morning, or evening altitude profiles for all navigational bodies. Save current data and up to 7 previous fixes. Each session can have up to 25 observations on up to 3 navigational bodies. Supports running fixes. 2 different methods for determining a fix. Supports practice sights using a bubble horizon, artificial horizon, or large body of water using dip short. Integration with iOS Maps to display saved fixes. Also supports setting the assumed position by dropping a pin on the map. Integration with iOS location services to obtain position and magnetic variance. Integration with iOS devices with compass for direction-up display of the star map and to show azimuth of object currently being observed. Integration with iOS data network for setting UTC time from network time using NTP servers.
