Azimuth

Calculates azimuth and elevation angle in the local horizon system for a sky position given in equatorial coordinates (RA Dec J2000).Function Call: [Az El] = RADec2AzEl(350,58, '2008/02/18 13:10:00',60,15,0)Input:RA - Right ascension (J2000) of sky position in degrees (0:360)Dec - Declination...

Predict the azimuth and elevation of the Sun within +/- 1 degree at any geodetic latitude, longitude and altitude.Function Call: [Az El] = SolarAzEl('2008/02/18 13:10:00',60,15,0)Input List:UTC Date and Time - Use format YYYY/MM/DD hh:mm:ssLatitude - Site Latitude in degrees -90:90 -> S(-)...

Using this script, you can generate a set of data regarding Sun Azimuth Positions at various instants of time for any location on Earth. This data can be used in many applications, like, in determination of orientation of any plane's azimuth from True North.The syntax is 'sun_azimuth_data' (no...

In 1975, Vincenty published a rapidly converging algorithm for computing the distance between points on an ellipsoidal earth. The algorithm is precise to within a few millimeters. Since then, his algorithm has since seen significant implementation in geodesy and engineering. After adjusting the...
