TITLE: South West Seismic Zone 2002, GPS Analysis [PDF_380k]
Date: November 2002
Author: John Dawson
Summary: This document overviews the GPS data analysis undertaken using the 2002 Geoscience Australia South West Seismic Zone (SWSZ) GPS data set. Unless specified otherwise all further dates in this report follow the SINEX date convention - YY:DDD[:SSSSS], where YY is a two digit year, DDD is the day of year and SSSSS is the second of the day. GPS antenna and receiver names follow the International GPS Service (IGS) convention.
TITLE: Geoscience Australia Activities Related to the International GPS Service [PDF_1.5Mb]
Forum: IGS 2002 Analysis and Data Workshop
Location: Ottawa, Canada
Date: April 2002
Author: Manning et al.
Summary: The International GPS Service (IGS) and Geoscience Australia continue to have a strong relationship. Geoscience Australia (formerly the Australian Surveying and Land Information Group, AUSLIG) currently provides data from 15 permanently tracking GPS stations to the IGS, these stations are known as the Australian Regional GPS Network (ARGN). Future development of the ARGN will focus on the availability of near real time data and the augmentation of precise clocks and meteorological equipment at selected stations. Additionally Geoscience Australia has been an IGS Regional Network Associate Analysis Centre (RNAAC), contributing an Australian regional GPS solution, for almost six years. Apart from these contributions to the IGS, NMD is currently making use of IGS products, including precise GPS trajectories, Earth Orientation Parameters (EOP) and station coordinates and velocities in the delivery of an Internet based precise GPS processing service (AUSPOS) widely used by both the Australian and International GPS communities. In this poster Geoscience Australia’s IGS related activities are reviewed.
TITLE: The AUSPOS Systems Description [PDF_1.5Mb]
Date: September 2001
Author: John Dawson, Ramesh Govind & John Manning
Summary: The AUSLIG’s (now Geoscience Australia) Online GPS Processing Service (AUSPOS) provides users with the facility to submit via the Internet, dual frequency geodetic quality GPS RINEX data observed in a 'static' mode and receive rapid turn-around precise coordinates. The service is free and provides both ITRF and GDA94 coordinates. This Internet service takes advantage of both the International GPS Service (IGS) product range and the IGS GPS network and works with GPS data collected anywhere on Earth. Aspects of the design, implementation, usage and future plans of this system are reviewed. The AUSPOS system can be found at www.ga.gov.au/geodesy/sgc/wwwgps/

TITLE: GPS/GLONASS Geodesy [PDF_1.46Mb]
Forum: Proceedings, 4^th International Symposium on Navigation Technology and Applications
Location: Brisbane, Australia
Date: 20 - 23 July, 1999
Author: Ramesh Govind, John Dawson & Geoff Luton
Summary: Data and graphics from this Symposium. The AUSLIG (now Geoscience Australia) Space Geodesy Analysis Centre undertakes Global Positioning System (GPS), Satellite Laser Ranging (SLR), Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) and GLONASS data processing and analysis, and the combination of these techniques. In addition, development of the combination solutions have further progressed to include Very Long Baseline Interferometry (VLBI) results, the Solution Independent Exchange Format (SINEX files), which are produced by VLBI Analysis Centres.
TITLE: The Monitoring of National and Regional Geodetic Networks [PDF_720k]
Forum: Proceedings, International Workshop in Advances in GPS Deformation Monitoring
Location: Perth, Australia
Date: 24 - 25 September, 1998
Author: John Manning, Ramesh Govind & Peter Holland
Summary: AUSLIG (now Geoscience Australia) is the agency with principal responsibility for geodesy at federal government level in Australia. AUSLIG (now Geoscience Australia) coordinates its national geodesy activities with State and Territory agencies through the Intergovernmental Committee on Surveying and Mapping. The national geodesy program involves the monitoring of movement of the Australian landmass and offshore territories as the basis of a geodetic framework for the Australian Spatial Data Infrastructure. Crustal deformation in a global context requires global observations to best monitor the slow deformation of the earth, and to provide the information essential to support satellite based positioning systems such as GPS. Geodetic data is acquired by AUSLIG (now Geoscience Australia) from a network of global positioning system and satellite laser ranging stations located in the region and is distributed through the internet in the form of data and analysis products to the national and global community. This contribution enables use to be made of the global systems for local application of GPS for deformation purposes. This paper describes the AUSLIG (now Geoscience Australia) geodesy program and its contribution to the monitoring of national, regional and global geodetic networks.
TITLE: The Asia and the Pacific Regional Geodetic Network (APRGN) [PDF_58k]
Forum: GEODYSSEA Concluding International Symposium
Location: Penang, Malaysia
Date: 14 - 18 April, 1997
Author: John Manning & Ramesh Govind
Summary: The second meeting of the Permanent Committee on GIS infrastructure for Asia and the Pacific was convened in Sydney on 30 September 1996. The plenary session of the meeting adopted three resolutions proposed by the Regional Geodetic Networks Working Group (GNWG). The role of the GNWG is "to establish and maintain a precise relationship between permanent geodetic observation sites across the region to provide a base on which to build a homogeneous Spatial Data Infrastructure (SDI) for Asia the Pacific Region". For the purpose of this project the definition of SDI includes products for geodynamics applications; meeting accuracy specifications for geodynamics are therefore implicit.
TITLE: Geodetic Fixing of Tide Gauge Benchmarks of the Australian Baseline Sea Level Monitoring Array: Results of the May 1995 GPS Campaign [PDF_170k]
Forum: Ocean Atmosphere Pacific Conference
Location: Adelaide, Australia
Date: October, 1995
Author: Ramesh Govind, Gary Johnston & Geoff Luton
Summary: In order to monitor changes in absolute sea level, the vertical motion of the crust at the tide gauge location must also be monitored in an accurate, global terrestrial reference frame. During the last week of May 1995, five days of GPS data was observed at over 30 inland and coastal sites related to the tide gauge array. In addition, the data set includes 10 Australian Fiducial Network (AFN) sites, 3 Australian Antarctic Territory sites and 17 global sites of the International GPS Service for Geodynamics (IGS). The computations are undertaken in stages that comprise the precise orbit determination of the GPS satellites from the IGS/AFN global data set and, then estimating the positions of the inland and coastal tide gauge benchmarks. The data set and the computation procedure (including observable, orbit, and station modelling) are briefly described and the results for this epoch are presented.
