DETAILS
This Perl script finds the orbiting body closest to the given position at the given time as seen from a pre-programmed location: Parliament House, Canberra ACT, Australia.
The arguments are the desired time (in a format suitable for Date::Manip), the right ascension (in decimal degrees, not hours), the declination (also in decimal degrees), and the names of one or more files containing satellite TLE orbital element sets.
The output is the OID of the closest body at the given time, and its right ascension, declination, and angular separation from the given position in degrees, as seen from the observing station.
