Station locations on the ATCA
There are 45 stations on which the antennas usually reside. There are 39 on the 3km east-west track (labelled W), 5 on the north-south track (labelled N), and 1 for the 6 km antenna. The east-west stations are numbered according to their distance from the eastern end in units of 15.306 m and starting at W0. The north-south stations are numbered according to their distance from the intersection with the east-west track at W106 and in units of 15.306 m.
The following table shows the station name (Stn
), and
the corresponding distance in metres (Dist
). The table also
gives the names of some stations in an old naming convention.

Also of relevance are the array configurations themselves.
Note: The design of the primary monitor system places the following restrictions on some stations:
Station | Hosts only |
---|---|
W0 | CA01 |
W2 | CA01 CA02 |
W4 | CA01 CA03 CA03 |
W6 | CA01 CA02 CA03 CA04 |
W172 | CA02 CA03 CA04 CA05 |
W173 | CA02 CA03 CA04 CA05 |
W182 | CA03 CA04 CA05 |
W189 | CA04 CA05 |
W190 | CA04 CA05 |
W195 | CA05 |
W196 | CA05 |
That is, the end stations of the east-west track do not take all antennas. This is only of relevance if a shuffle of antennas is being used.
The following stations are not used by any standard arrays: W6, W12, W14, W16, W129, and W189.
Note that some of these were used in obsolete or special arrays.
