ezAlmanac
Detailed App Info:
Application Description
*** Now includes full HO-229 table generation! Automatically does the sight reduction and graphing of your Almanac data! Saves up to 25 previous sights. Determine your fix from the plotted data.
*** Now supports Nautical Almanac page generation for the years 1973 - 2059!
ezAlmanac is a digital multi-year nautical almanac with digital sight reduction tables for use in celestial navigation. Use it the same way you would use the published Almanac and HO-229 tables, or use the “Expert” tab to do the work for you!
Features:
▪ Generates daily Nautical Almanac data from 1973 to 2059. Displays all data in the same format as the published Nautical Almanac.
▪ Generates all pages and interpolation tables for HO-229 "Sight Reduction Tables for Marine Navigation".
▪ For greatest accuracy, uses IERS Bulletin B earth orientation final values for calculating data from 1973-8/2012. Uses IERS predicted earth orientation values for 9/2012 to 8/2013 calculations.
▪ Performs all astronomical calculations using NOVAS 3.1 software developed by the US Naval Observatory.
▪ Includes Almanac Increment and Correction Tables, allowing you all the tables needed to generate a GHA and Declination value within the app.
▪ Includes Altitude Correction Tables, allowing you to generate an Ho value for an observation made with a sextant.
▪ “Expert” tab automatically generates the correct Universal Time using your local date, time and time zone.
▪ “Expert” tab calculates the GHA and Dec for a selected navigational body using almanac table values.
▪ “Expert” tab calculates the Ho value from the entered object altitude measured by the sextant, height of eye, and atmospheric conditions using the almanac table values.
▪ “Expert” tab displays all almanac values used for the GHA, Dec, and Ho calculations, and can take you to the almanac page with the value highlighted.
▪ “Expert” tab performs sight reduction and graphing of the almanac data, and can take you to the HO-229 page with the values used highlighted.
▪ Drag the DR position on the sight reduction plot to recalculate the sight reduction from a refined position.
▪ Supports running fixes.
▪ Saves up to 25 previous observations.
▪ Integration with iOS® location services to automatically set your position from the device.
▪ Supports both standard (US) and metric units for temperature, barometric pressure and height of eye values.
▪ Supports zoom and pan on all almanac and HO-229 pages.
