Title: Conversion of New Zealand's 30m Telecommunication Antenna into a Radio Telescope Author: Lewis Woodburn, Tim Natusch, Stuart Weston, Peter Thomasson, Mark Godwin, Sergei Gulyaev (version, v3)
We describe our approach to the conversion of a former 100-foot (30-m) telecommunication antenna in New Zealand into a radio telescope. We provide the specifications of the Earth Station and identify the priorities for the conversion. We describe implementation of this plan with regards to mechanical and electrical components, as well as design of the telescope control system, telescope networking for VLBI, and telescope maintenance. Plans for RF, front-end and back-end developments based on radio astronomical priorities are outlined.
Title: Warkworth 12-m VLBI Station: WARK12M - 2012 Authors: Stuart Weston, Hiroshi Takiguchi, Tim Natusch, Sergei Gulyaev
The Warkworth 12-m Radio Telescope is operated by the Institute for Radio Astronomy and Space Research (IRASR) at AUT University, Auckland, New Zealand. This report briefly reviews the characteristics of the 12-m VLBI station. We report on a number of activities and technical developments.
Delegates who visited the Warkworth Observatory included, legendary Australian astronomer Dr Ron Ekers who helped demote Pluto from planet status, WiFi inventor Dr John O'Sullivan, and observatory director professor Sergei Gulyaev. North Auckland will miss out on a radio telescope dish site if Australia and New Zealand win the right to host the $2.5 billion international Square Kilometre Array, a mega-science radio astronomy project.

Title: Warkworth 12-m VLBI Station: WARK12M Authors: Sergei Gulyaev, Tim Natusch, Stuart Weston, Neville Palmer, David Collett
This report summarises the geodetic VLBI activities in New Zealand in 2010. It provides geographical and technical details of WARK12M - the new IVS network station operated by the Institute for Radio Astronomy and Space Research (IRASR) of Auckland University of Technology (AUT). The details of the VLBI system installed in the station are outlined along with those of the collocated GNSS station. We report on the status of broadband connectivity and on the results of testing data transfer protocols; we investigate UDP protocols such as 'tsunami' and UDT and demonstrate that the UDT protocol is more efficient than 'tsunami' and 'ftp'. In general, the WARK12M IVS network station is fully equipped, connected and tested to start participating in regular IVS observational sessions from the beginning of 2011.
A South African consortium is also on the shortlist to build the project. The winner will be chosen in 2011 by an independent scientific community panel called the International SKA Site Advisory Committee (ISSC). The panel has already cut two of the original four contenders: China and Argentina / Brazil. The 12m dish, sitting on an 8-tonne pedestal, was built by Michigan's Patriot Systems, then shipped across the Pacific before being assembled at its new home at the Warkworth Satellite Station, north of Auckland.
At 4.15pm today, AUTs $1 million radio telescope will go live the first stage in a trans-Tasman bid to win right to build a $NZ4 billion megascience project called the Square Kilometre Array (SKA). The dish, built by Michigans Patriot Systems and assembled at the Warkworth Satellite Station north of Auckland, will serve as a proof-of-concept project, along with 44 dishes in Australia.
