Equatorial To Horizontal

Demo Code



public class EquatorialToHorizontal {
    public static void main(String args[]) {
        double altitude = 0;
        double azimuth = 0;
        double d = Math.toRadians(20);
        double h = Math.toRadians(5);
        double l = Math.toRadians(6);

        altitude = Math.asin(Math.sin(l) * Math.sin(d)
                + (Math.cos(l) * Math.cos(h) * Math.cos(d)));
        azimuth = Math.acos((Math.cos(l) * Math.sin(d) - (Math.cos(d)
                * Math.cos(h) * Math.sin(l))
                / (Math.cos(altitude))));

        System.out.println("Altitude is " + Math.toDegrees(altitude));
        System.out.println("Azimuth is  " + Math.toDegrees(azimuth));
