Universal astronomy ephemeris App for calculating high precision ephemeris
Astronomy ephemeris App for calculating high precision ephemeris and positions of Sun, Moon and the Planets for engaged amateur astronomers and planetary observers, prefering data and facts instead of pritty pictureapps. Planetdroid finds rise, culmination and set times, the beginning of seasons, lunar phases and planetary aspects.
New: Augmented reality AR view beta version: See the planet39;s positions live on a camera image and search your selected object with your phone Version 4.0
Since version 3.0 Planetdroid comes with a visibility diagram. You see the elevation above the horizon of your selected body white line of the current nicht and the elevation of the sun dark yellow line, as well as the twilight times. The horizontal black line ist the horizon, the vertical red line your selected time.
Since version 3.3 it is possible to save locations offline. The file containing the locations is sdcard.com.stricklinglocation.txt. It can be edited with any test editor. To start the editor, simply click menu in the location selection form.
Download elements for asteroids and comets from the internet.
Supports GPS localization.
Calculates select or deselect different items in the menu:
time of rise, culmination, set,
azimut of rise and set
equatorial right ascension and declination
ecliptical coordinates and distance
azimut an elevation
equation of time, true local time, sidereal time
diameter, brightness, central meridian, position angle of the axis
for comets and asteroids: motion velocity and direction
Civil, nautical and astronomic twilight
begin of the seasons, lunar phases, and lunar age
times of opposition, conjunction and greates elongation for planets.
time of perihelion for comets

On some devices without front camera Google Play Store will indicate, that Planetdroid is not compatible with your device. The front camera is needed for the augmented reality screen. If you like to install Planetdroid without using augmented reality, please install it from my website http:www.strickling.netandroidengl.htmPlanetDroid

Thanks to Mark Huss for his AstroLib containing the VSOProutines and to the translators Nenad Trajkovic Serbian, Alfredo Caronia Italian, IDris a.k.a. MANsur, GhostUnit Russian and Alexej Pace Maltese.
