iNA Digitial Nautical Almanac for iOS

By StarPilot $29.99

Developer's Description

iNA computes all ephemeris data available in the daily pages of the USNO Nautical Almanac. This information is required when doing astronomical computations for celestial navigation, local noon, sunrise, and others. The program computes GHA, Dec, SHA, SD, HP, magnitudes, sunrise, sunset, LAN, twilight times, moonrise, moonset, moon age and phase for sun, moon, 5 planets, and 173 stars. INA also computes addition useful information not included in the Nautical Almanac such as ephemeris for Mercury, Hc at LAN, bearing of sunrise and sunset (amplitudes), and the GHA of Aries midway between civil and nautical twilights for star planning.

INA's internal celestial almanac is valid for the years 1582 through 2800 AD.
