Description

AstroNav, the one-stop solution to finding your position with celestial bodies. Use this app in conjunction with its inbuilt sextant or a commercial one to find your position on Earth at any time. All you need is the Sun, Moon, a star or planet in the sky and a steady hand. You do not even need a sextant to use this app as this functionality is built in and can give you accuracies to within a degree with practice, which is good enough to give your position to a few miles. It is of course not a replacement to the iPhones ability to find your location nor is it as accurate, but this is how sailors and explorers used to navigate for hundreds of years and it gives a tremendous feeling of achievement to find your location with only a few celestial bodies! Features: -Inbuilt sextant which can be calibrated for time (internet connection required) and angle correction either using the horizon or a known body as a guide. -Sight Reduction with over 50 stars, Sun, Moon, Venus, Mars, Jupiter and Saturn. -A map to display your intercepts, the option to show the full position circle around the celestial body and a probability heat map for your position fix. -A tutorial and glossary to get you started. The data and algorithms used are accurate to within a fraction of a minute and have been compared to commercially available almanacs, giving a precision of better than ±0.4’ (±1.0' for the Moon). They consider the effects of: precession, nutation, aberration, parallax and more. Ideal for the beginner who has an interest in celestial navigation but is not yet ready to invest a large sum of money on a sextant and the sextant users who does not like the chore of doing calculations on paper.
