About iMariner Celestial Navigation
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)
- 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).

iMariner has been inspirated by astronomical works of the following people.
