Australian Space Academy
The following table gives look angle data for the geosynchronous satellite belt as visible from the Australian
Space Academy at Meckering in Western Australia. The look angles are given in both horizon coordinates (azimuth and elevation) and celestial (astronomical or equatorial) coordinates (hour angle and declination).
The first column is the geosat longitude. The next two columns are the horizon look angles (elevation and azimuth). The next two columns are the astronomical look angles (hour angle in hours and declination in degrees). The penultimate column is the line of sight range to the geostationary satellite in kilometres, while the final column is the great circle distance along the Earth to the subsatellite point on the Earth's surface, directly below the satellite.
The sign convention used here is that positive angles are east and negative angles are west.
