Hi all, The direction of motion of a satellite relative to a geographic parallel is dependent on the latitude of the location. For example, for an orbital inclination of 12.0deg, a satellite cannot pass overhead at a geocentric latitude greater than 12.0deg N or 12.0degS and would be moving due east (Az=90deg) at the north and south apex. It would only have an angle of + or - 12.0 deg when crossing the equator. The geographical/geodetic latitude of Armstrong/Bustinza is ~32.76S which represents a geocentric latitude of 32.59S. For an azimuth of 78.56deg at this geocentric latitude, the implied orbital inclination is 34.3deg. Hope this helps in narrowing down the candidates.
