Star data is from the Bright Star Catalog (5th Revised Edition), comprising the 9110 brightest stars using J2000 equatorial positions and the International Celestial Reference Frame (ICRF). Corrections are performed for proper motions and parallax.
Planet ephemeris data from Jet Propulsion Laboratory using the DE405 database. DE405 is JPL's latest planetary ephemeris with correction for both nutations and librations. DE405 uses the J2000 International Celestial Reference Frame (ICRF). The portion of this database provided with Pocket Stars covers the years CE 2000 to CE 2020. Other ephemeris date ranges are available for download.
Celestial Navigation Features
Reduction from sextant altitude to observed altitude for any of the 9110 stars, nine planets, and sun and moon.
Corrections for observer height (DIP), refraction (temperature and atmospheric pressure), and vessel movement.
Position from intercept and azimuth by calculation for multiple sextant observations following procedures in The Nautical Almanac by the United States Naval Observatory.
Any number of sextant observations can be individually enabled to compute a best fit when computing a FIX. Results may be plotted, showing the assumed position (AP), FIX, and observations with intercepts and amplitudes.
Intermediate calculations for each observation can be displayed, with selectable formats (DD.dddd, DD MM.mm, DD MM SS) for degrees, minutes, seconds.
Other Features
Rise, set, and meridian times for all solar system bodies.
Lunar Phase calendar and animation showing the relative positions of the earth, moon, and sun.
Images and physical data for planets, moon and sun, Messier and Caldwell objects.
Great Circle distance calculator
Range and bearing calculator
Horizon distance calculator
Julian Day calculator
