Australian Geodetic Infrastructure development program

The Federal Department of Education, Science and Training has granted $15.8 million dollars (AUD) to the upgrade of Australia's geodetic infrastructure. This grant is aimed at improving Australia's research capability in geodesy and all of the related spatial fields that rely on accurate positioning. It will of course only achieve these outcomes by integrating effectively into the existing and planned Global Geodetic Observing Systems. The $15.8 million grant will also be supplemented with funds from the state governments, particularly in the area of GNSS deployment.

The current plans for infrastructure improvement include:

  • 3 New VLBI Antenna (Mt Pleasant, Yarragadee, and Katherine (North Central Australia))
  • VLBI software correlator
  • 1 Absolute gravimeter
  • 1 Tidal gravimeter
  • a Multi pier gravity calibration facility (Mt Stromlo)
  • upgrade to the laser power at Mt Stromlo for more effective MEO ranging
  • FTLRS campaign at Burnie (Tasmania) for altimeter calibration
  • Approximately 110 new GNSS sites

“Scientific and Fundamental Aspects of the Galileo Programme”

2-4 October 2007, Toulouse, France.

An international colloquium on fundamental aspects and scientific applications of Galileo and GNSS will be held in Toulouse in October 2007. ANAE (Académie Nationale de l’Air et de l’Espace), Bureau des Longitudes, Académie de Marine and ESA (European Space Agency), are the main instigators of this colloquium meant to contribute to the 50th anniversary celebrations of the launch of Sputnik.

The colloquium will address three major issues:

  • The fundamental aspects of navigation by satellites and Galileo: geodetic and temporal reference frames, relativistic frame, on board and ground clocks, orbits, radiative environment in orbit, intersatellite links, fundamental aspects of propagation, tropospheric and ionospheric corrections, calibration and validation, relations with international organisations (BIPM, IGS).
  • Scientific applications in meteorology, geodesy, geophysics, space physics, oceanography, land surface and ecosystem studies, using either normal or reflected signals, differential measurements, phase measurements, occultations, in real or delayed modes, using receivers placed on the ground, in airplanes or in scientific satellites.
  • Scientific developments in physics and dealing with future systems, particularly in testing fundamental laws, in astronomy, in quantum communication, and in developing clocks or experiments based on GNSS.

This colloquium intends to bring together leading members of the European scientific community and their international partners. One of its aims is to propose to Galileo partners means of enhancing the scientific use of Galileo and to contribute to GNSS development based on scientific approaches.

Symposium on Terrestrial Gravimetry: Static and Mobile Measurements

St. Petersburg, Russia, 20 - 22 August 2007.

The meeting is being organized by Leonid Vitushkin, Chair of the Study Group 2.1 (Comparison of Absolute Gravimeters) of Commission 2. The symposium is officially sponsored by the IAG, co-sponsored by the Institute of Earth Physics of the Russian Academy of Sciences, Moscow; and the BIPM.

The topics of the conference will include the design and investigations of the measuring instruments for the absolute and relative measurement of the gravity field, their applications for terrestrial, shipboard and airborne platforms, and in the metrology of gravimetry. Traditional free-fall, superconducting, and spring-type gravimeters, gradiometers, and new technologies, such as based on atom interferometry, will be especially welcome, as will results and methodologies of static and mobile campaigns, as well as current and future networks. Geophysical interpretation of results and connection with space-borne systems are of limited interest, since the emphasis is on terrestrial (including airborne) instrumentation and methods to extract gravity field measurements for a variety of applications.

More details about the symposium will soon be available on the website of the meeting. Contact person of the Local Organising Committee is Mrs. Margarita Grishina (mgrishina@eprib.ru).

1st AFREF Technical Workshop

Cape Town, South Africa

9-13 July 2006

Introduction and Background

AFREF is designed to unify the co-ordinate reference systems of Africa to create an environment in which all activities requiring sound geo-spatial information such as surveying, mapping, geographical information systems, navigation, engineering projects, atmospheric and geophysics research and applications and disaster monitoring and mitigation are based on a uniform modern international co-ordinate reference system. The project has been initiated from within Africa and is being implemented, managed and executed by African geodesists, surveyors and scientists with assistance from the international community.

Although the ideals and concepts of AFREF have been debated for a number of years, the scientific and technical aspects of the project have not been highlighted in a dedicated workshop. In order to close this gap, a technical workshop was held in Cape Town, South Africa between from 9 to 13 July 2006.

Aims and Objectives

The primary objective of the workshop was to introduce representatives of National Mapping Organisations (NMO’s) and academic institutions of African countries to the scientific and technical aspects of the AFREF project. To achieve this, a number of internationally recognised geodesists and Global Navigation Satellite Systems (GNSS) specialists were invited to give presentations on scientific, technical and practical topics of importance to the project. An equally important objective was to facilitate the interaction between the representatives of NMO's and presenters in an informal atmosphere.

Sponsorship

Direct and indirect sponsorship for the workshop was provided by a number of organisations. Airfares and/or accommodation for delegates from Africa, the general running costs of the workshop and social events were paid through direct sponsorship. Indirect sponsorship for the workshop was provided by the home organisations of presenters who paid for their airfares and accommodation. The following government or non-government organisations provided sponsorship for airfares, accommodation or logistic costs (in alphabetical order):

  • Chief Directorate: Surveys and Mapping of the Department of Land Affairs of South Africa (CDSM);
  • International Association of Geodesy (IAG);
  • National Research Foundation of South Africa (NRF);
  • University of Cape Town (UCT);
  • University NAVSTAR Consortium Inc. (UNAVCO); and
  • United Nations Office for Outer Space Affairs (UNOOSA).

The following suppliers of GNSS equipment provided sponsorship for the two social events (in alphabetical order):

  • Leica Geosystems Africa (Pty) Ltd;
  • OmniSTAR Pty Ltd (South Africa);
  • Optron (Pty) Ltd;
  • Sokkia-RSA (Pty) Ltd; and
  • VI Instruments Division of Hudaco Trading Ltd.

The willingness of the above organisations to support the workshop is indicative of their support for the AFREF project and is to be commended.

Country Representation

There was a good geographical distribution of the 17 African countries represented by 38 delegates. In addition, 4 representatives from 2 of the 3 regional centres for mapping in Africa also participated in the workshop viz. the Regional Centre for Mapping of Resources for Development (RCMRD) based in Kenya and the Nigerian based Regional Centre for Training in Aerospace Surveys (RECTAS). 15 speakers gave presentations.

Programme

Apart from an introductory session of formal welcomes and preamble speeches, the programme was divided into 10 sessions covering 4 broad themes viz.:

Background and reports (6 presentations)

Reference systems and frames (7 presentations)

Geodetic stations and permanent GNSS stations (9 presentations)

Data processing and analysis (2 presentations)

The presentations were all of a very high quality and were extremely informative and useful in content. Of great interest to participants was a presentation on the SIRGAS project and the lessons that could be learnt from it. SIRGAS is a project to unite the geodetic reference systems and frames in South America and is very similar to AFREF in its objectives.

A visit was arranged to the offices of the Chief Directorate: Surveys and Mapping in which the control centre for the South African network of permanent GNNS stations (TrigNet) is situated. Another visit was arranged to the Hermanus Magnetic Observatory where, besides being the location of one of the TrigNet remote sites, research is being carried out on ionospheric mapping using TrigNet GNSS data.

Objectives achieved

It is believed that the primary objective of the AFREF Technical Workshop was achieved. The AFREF Steering Committee of the United Nations Economic Commission for Africa’s Committee on Development Information-Geo (CODI-Geo) confirmed this at their meeting held on Friday 14 July. It is believed that the delegates who attended the workshop sessions responded well and learned a great deal of the aims and objectives of AFREF as well as the theoretical, technical and practical implications of the project. It is also believed that delegates will continue to strongly support the project. A critical factor in succeeding in these aims and objectives, however, will rest with the AFREF Steering Committee who will have to maintain the high level of interest in the project through continuing communication, seminars and workshops.
