Application for computing positions of celestial bodies of solar system

The Astronomical Almanac application calculates the exact position of objects in the solar system, their sunrise and sunset for a given time and place. The time of the onset of the lunar phases and lunar days is also calculated.

To improve the accuracy of determining the location of the observer, geographical maps are used.

Calculations are made in the date range from 3000 BC. until 3000 A.D.

The program uses the Steve Moshier algorithms.

Designed for astronomical observations.

The following parameters are calculated for celestial objects:

 - UT, TDT, Julian Day

 - Sideral time, Delta T
