Lunar Azimuth and Altitude Estimation Algorithm

Predict the Lunar Azimuth and Altitude within +/- .2 deg of any lat and lon for a given UTC

Vous suivez désormais cette soumission

This algorithm will accept a Latitude, Longitude and Altitude location as well as a specific universal coordinated time. It will use this information and calculate the position of the moon in a local coordinate frame (az and alt aka az and el).

Example Function Call:
[Az El] = LunarAzEl('1991/05/19 13:00:00',50,10,0)

Input List:
UTC Date and Time - Use format YYYY/MM/DD hh:mm:ss
Latitude - Site Latitude in degrees -90:90 -> S(-) N(+)
Longitude - Site Longitude in degrees -180:180 W(-) E(+)
Altitude - Site Altitude in km

Output List:
Az - Lunar Azimuth angle in degrees
El - Lunar Elevation/Altitude Angle in degrees
