Ephemeredes of the Sun and Determination of Position 2.0   (details) 28 ENG   64 KB
Provides quick and accurate ephemeris of the sun without the bulk or cost of the yearly almanac. The program can be used to calculate the declination (Dec) and Greenwhich hour angle (GHA) of the sun for any time between March 1, 1900 and February 28, 2100. If the sunís observed altitude and your assumed position are also entered the program will provide the calculated altitude (Hc), azimuth angle (Azn) and intercept (Ic) thus allowing you to plot a line of position (St Hilaireís method).
