Method Detail

ECEF_To_Geo

public static double[] ECEF_To_Geo(double[] ECEF_Coords)

Converts ECEF coordinates to Geocentric coordinates Conversion from Earth-Centered, Earth Fixed coordinates (x, y, z) to Geocentric coordinates (Latitude, Longitude, Height) with units {rad, rad, meters}

Parameters:

ECEF_Coords - The List of X,Y,Z values to convert to Geocentric coordinates

Returns:

LatLong double array

LatLong[0] = Latitude in radians

LatLong[1] = Longitude in radians

LatLong[2] = Altitude in meters

EquatorialToLocalHorizontal

public static double[] EquatorialToLocalHorizontal(double RA,
                                                   double Dec,
                                                   double Lat,
                                                   double Long,
                                                   T_JulianDate t)

Converts Right Ascension and Declination values to local Azimuth, Elevation Equatorial (RA, Dec) with units (deg, deg) are converted to Local horizontal coordinates (Azimuth, Elevation) with units {deg, deg}

Parameters:

RA - The Right Ascension coordinate to convert

Dec - The Declination to convert

Lat - The Latitude of the location the observer is at

Long - The Longitude of the location the observer is at (reckoned negative WEST)

t - The T_JulianDate object representing the time for the conversion

Returns:

AzEl double array.

AzEl[0] = Azimuth in degrees reckoned clockwise from north.

AzEl[1] = Elevation in degrees.

main

public static void main(java.lang.String[] args)

Test program for T_Coordinates

Parameters:

args - Arguments
