Developer's Description

iMariner Celestial Navigation is a complete toolbox: sight, fix, meridian, starfinder, solar compass. Also embedded: nautical almanac (sun, moon, planets, starts) and astronomical computation (no more need for HO-249/HO-229 tables). v2.3: Update the value of DeltaT (67.4s) for 2013 from maia. usno. navy. mil. displays almanac informations: Sun, Moon, Venus, Mars, Jupiter, Saturn and 92 brightest stars. At this step, you can use these almanac data with HO. 249 tables, if you want to reduce manually. reduces a sight: getting your observed altitude and the precise time, it calculate Intercept and Azimut. You don't need any calculation. Simply report Intercept and Azimut to your navigational chart. You can save your observations by passages and send them by email in CSV format. take a fix: with two sights, iMariner is able to calculate your position (latitude/longitude). meridian passage: iMariner helps you to take observations mandatory to know your position (latitude/longitude). sight preparation: iMariner proposes you the best objects, here position (azimut and elevation), and the approximate time of the day the observation can take (nautical_twilight or nautical dawn). iMariner is a standalone application. It doesn't require internet connection. It is light and calculations are optimized to save energy on your boat. Includes a solar compass (and moon compass too).
