The Warkworth 12m Radio Telescope[1] at the Warkworth Radio Astronomical Observatory is operated by the Institute of Radio Astronomy and Space Research of Auckland University of Technology. It was constructed in 2008[2][3][4] and is located just south of Warkworth off SH1 about 50 km north of Auckland, New Zealand.

Technical information[edit]

12m diameter antenna designed and constructed by COBHAM Satcom, Patriot Products division.

Antenna type        :  Fully steerable dual shaped Cassegrain
Main dish Diam      :  12.1 m
Secondary Refl Diam : 1.8m
Focal Length        : 4.538 m
Surface precision   :  0.35 mm (RMS)
Pointing accuracy   : 18"
Wavelength          : L-Band, S-Band and X-Band
Mount               : alt-azimuth
Slewing rates       : (5 deg/s in azimuth and 1.25 deg/s in elevation)
Acceleration        : (1.3 deg/s/s)

Dual polarization S and X-band feeds from COBHAM with room temperature receivers, the receiver systems cover 2.2 to 2.4 GHz at S-band and 8.1 to 9.1 GHz at X-band.

Research activity[edit]

In 2010 this dish was used for several Very Long Baseline Interferometry observations[5][6] as part of the Australian Long Baseline Array.[7]

It will also from 2011 be part of the International VLBI Service for Geodesy and Astrometry.[8] As such, it is also co-located with a LINZ/GeoNet 'PositioNZ' GNSS [9] station to help future inclusion in the definition of the International Terrestrial Reference Frame (ITRF).
