• Title: Antarctic 2001 - Casey (Tech. Report 8) [PDF_500k]
  Date: January 2002
  Author: Gary Johnston & Paul Digney
  Summary: In October 2001, maintenance work on the GPS and ancillary equipment at Australia’s Antarctic base at Casey was carried out. This site forms part of the Australian Regional GPS Network (ARGN). In addition accurate measurements were taken of the relationship between the ARGN monument and the three reference marks to check for any possible local movement since the site was established in December 1993. These measurements also provide a reliable base measurement for future monitoring. A GPS connection and difference in height by optical levelling between the ARGN monument and the tide gauge benchmark was also completed. This report documents the methods and results of these surveys.
  
• Title: Antarctic 2000-2001 (Tech. Report 5) [PDF_1.9Mb]
  Date: September 2001
  Author: Gary Johnston & Paul Digney
  Summary: The 2000/2001 Antarctic Geodesy Summer Program consisted of a number of distinct components including - ARGN reference mark surveys and Orthometric height connections at Mawson and Davis. This report details the work completed in the 2000/2001 summer season, by AUSLIG (now Geoscience Australia) geodetic surveyors between November 2000 and March 2001.
  
• Title: Heard Island 2000 (Tech. Report 6) [PDF_4.2Mb]
  Date: June 2001
  Author: Bob Twilley
  Summary: The main objectives of the 2000 geodetic survey of Heard Island were to upgrade and extend the existing geodetic survey network to give a better coverage of the island and to establish accurate, globally compatible coordinates for all spatial data applications on the Island. In addition, GPS observations would provide information for the long-term measurement of horizontal and vertical movement. In the long term, these fundamental positions will provide information on the contemporary motion of Heard Island for comparison with geological records, with special emphasis on the Australia-Antarctic separation and the mid ocean ridge. In the meantime they provide a consistent and globally compatible spatial framework for all other studies on the Island. This report documents the methods and results of these surveys.
