for hosting the Central Bureau of the International Gravity Field Service



The International Gravity Field Service (IGFS) is a unifying ‘umbrella’ IAG service which

·         coordinates collection, validation, archiving and dissemination of gravity field related data,

  • coordinates exchange of software for gravity field activities,

·         coordinates courses, information materials and general public outreach relating to the Earth’s gravity field.

The overall goal of the IGFS is to coordinate the servicing of the geodetic and geophysical community with gravity field related data, software and information. The combined data of the IGFS entities data will include satellite-derived global models, terrestrial, airborne and marine gravity observations, time-dependent gravity data, GPS levelling data, digital models of terrain and bathymetry, as well as ocean gravity field and geoid from satellite altimetry. Thus both the static and the temporal variations of the Earth’s gravity field will be covered by the IGFS.

2009 ILRS Technical Workshop on SLR Tracking of GNSS Constellations

Metsovo, Greece, Sept. 14-19, 2009


Dear Colleagues,


We have the pleasure to announce that the International Laser Ranging Service (ILRS) in collaboration with the National Technical University of Athens, Greece (NTUA) is organizing an ILRS Technical Workshop entitled:

SLR Tracking of GNSS Constellations

50 Years of Satellite Geodesy and Geodynamics

in Metsovo, Greece, from September 14 to 19, 2009, on the occasion of Prof George Veis 80th birthday and the 50th anniversary of his doctoral thesis, a document that laid the foundations of satellite geodesy. Details and the Second Circular are available from the workshop web page http://www.ntua.gr/MIRC/ILRS_W2009.



  • Overview of the two techniques with emphasis on their synergism
  • Review of GNSS and SLR constellations & networks and current stale of the art
  • Satellite geodesy applied in geodynamics, POD, positioning, gravity, etc.
  • Survey of the likely gains in science from SLR tracking ofGNSS constellations
  • Examine approaches to help accomplish the goals set by GGOS, investigating options  such as:

·         higher repetition rates,

·         optimal normal point formulation,

·         interleaving tracking of targets, better sampling of orbits,

·         allocating targets to sub-networks, etc.

  • Optimization of the network design and deployment of the appropriate space segment
  • Discussion of the fundamental differences, geometric and dynamic, between geodetic cannonball type targets (LAGEOS) and the complicated GNSS spacecraft
  • Discussion of applications specifically enabled through the synergism of the two techniques. e.g. the likely improvement of LEO POD with the improved GNSS orbital products and their impact on Earth Observation products relying on these orbits (radar and laser altimetry, geopotential missions, atmospheric lidar and sounding missions, topography missions, SAR and InSAR missions, etc.).


We would like to invite you to participate in the workshop and submit presentations to the sessions of your choice.

We look forward to seeing you all in Metsovo!

Report on the 19th Symposium of the IAG Reference Frame Sub-commission for Europe (EUREF)

May 27-30, 2009 in Florence/Italy



At invitation of the Italian Military Geographic Institute (Istituto Geografico Militare - IGM), the IAG Reference Frame Sub-commission for Europe (EUREF) held its 19th Symposium from May 27-30, 2009 in Florence/Italy. The EUREF Technical Working Group (TWG) met as usual the day before the beginning of the symposium, i.e. on May 26.

The symposium took place in the conference hall of the Istituto Geografico Militare. Nearly 190 geodesists representing 29 countries met for this 2009 annual EUREF symposium. The attendees mainly represent universities, research centres and the NMCA’s (national napping and cadastre agencies). The EUREF Symposia are an open forum and may be attended by any person interested in the work of the Sub-commission. The symposium was opened by General C. Colella, Commander of the Italian Geographic Military Institute, further welcome addresses of the hosting institutions were presented by Prof. L. Surace, President of ASITA and General R. Panunzi, Commander of the Italian Army Logistic. On behalf of the IAG, Z. Altamimi, President IAG Commission 1 "Reference Frames" and J. Torres, President IAG sub-commission 1.3 "Regional Reference Frames" as well as J. Ihde, Chairman of the EUREF Sub-commission expressed their good wishes for a successful conference.

EUREF is the Reference Frame Sub-commission for Europe of the IAG (International Association of Geodesy), a component of the Regional Reference Frames Sub-commission, integrated in Commission 1-Reference Frames. The long-term objective of EUREF, as defined in its Terms of Reference, “is the definition, realization and maintenance of the European Reference Systems, in close cooperation with the pertinent IAG components (Services, Commissions, and Inter-Commission projects) as well as EuroGeographics”.

The results and recommendations proceeding from EUREF support the use of the European Reference Systems in all scientific and practical activities related to precise geo-referencing and navigation, Earth sciences research and multi-disciplinary applications. EUREF makes use of the most accurate and reliable terrestrial and space-borne techniques available, and develops the necessary scientific background and methodology.

Its activities are focussed on a continuous innovation and on the changing user needs, as well as on the maintenance of an active network of people and organizations, and may be summarized as follows:

  • to maintain the ETRS89 (European Terrestrial Reference System) and the EVRS (European Vertical Reference System) and upgrade the respective realizations;
  • to refine the EUREF Permanent Network (EPN) in close cooperation with the IGS;
  • to improve the Unified European Levelling Network (UELN);
  • to contribute to the IAG Project GGOS (Global Geodetic Observing System) using the installed infrastructures managed by the EUREF members.

These activities are reported and discussed at the EUREF Symposia, an event that occurs every year since 1990, with an attendance of numerous participants coming from nearly all countries in Europe and other continents, representing universities, research centres and the NMCA (National Mapping and Cadastre Agencies). It's an open forum, and may be attended by any person interested in the work of the Sub-Commission.

The organization of the EUREF Symposia has been and will be supported by EuroGeographics, the consortium of the European NMCA, reflecting the importance of the EUREF work for practical purposes. This involvement is consolidated by a formal liaison between EUREF and EuroGeographics.

For the year 2009 we had the kind invitation from the Italian Istituto Geografico Militare (IGM), to hold the 2009 Symposium in Florence, from 27 to 30 May.

The scientific programme covered the following topics:

  • Activities of the EUREF Technical Working Group (TWG)
  • New Developments in GNSS Networks
  • Modelling the Earth with GNSS
  • Mitigation of GNSS Error Sources
  • Height, Gravity, Geoid, and Combination of Techniques
  • Improvements and Densifications of the ETRS89
  • National Reports

In about 60 oral presentations (including National Reports) as well as 20 posters various aspects of EUREF and neighbouring topics were treated. The available texts will be published as usual in the EUREF Proceedings within the publications series of the German Bundesamt für Kartographie und Geodäsie (BKG). By courtesy of our colleague Carl Calvert, UK, a “Best Student Poster Award” was handed over again to a young scientist. This award was give to A. Graziani, Universitŕ di Bologna, for the submission of a poster by him together with R. Bertacia and P. Tortora entitled ‘Detection of the Multipath Effect in the ING2 GPS station with a new developed software’.

The scientific sessions were accompanied by a social programme with impressive arrangements of Italian hospitality and culture.

A detailed overview on this symposium (programme, participants, ppt-files of presentations, photo gallery

etc.) can be found in the EUREF homepage – see symposia. There also the previous symposia are documented.

The EUREF Sub-commission acknowledges the financial support given by EuroGeographics for the

enabling the participation of delegates from economical weak countries.

By courtesy of the Swedish colleagues the EUREF Sub-commission is invited to hold its 2010 Symposium in Sweden. Details will be published in the EUREF homepage in time.


Resolutions of the EUREF Symposium in Florence,  May 27-30, 2009


Resolution no. 1

The IAG Reference Frame Sub-commission for Europe (EUREF)

recognising that

 –  From December 2007 to January 2008 the Italian Rete Dinamica Nazionale (RDN) was observed and

 –  all the results were submitted to the EUREF Technical Working Group, where they were accepted as Class B standard

endorses the set of points for Italy submitted to the Technical Working Group as an improvement and extension of ETRS89.


Resolution no. 2

The IAG Reference Frame Sub-commission for Europe (EUREF)


 –  the importance of the INSPIRE Directive,

 –  and the importance of ETRS89 and EVRS to this Directive,

 –  and the requirement to implement this Directive by 2011/2016

and considering NMAs are responsible for their national realisations of ETRS89 and EVRS

encourages NMAs to make their expertise in these systems available to the other participants in the INSPIRE implementation process.


Resolution no. 3

The IAG Reference Frame Sub-commission for Europe (EUREF)


 –  the importance of ETRS89 and its future maintenance

 –  and the importance of the national realisations of ETRS89 in use today

invites the member countries of EUREF to submit coordinates of EPN stations in their national realisation of ETRS89 to the TWG before September 15, 2009.


Resolution no. 4

The IAG Reference Frame Sub-commission for Europe (EUREF)

noting that past EPN data analysis was based on different reference frame realisations, orbits, Earth orientation parameters, standards and analysis strategies

and recognising that, therefore, the historic coordinates and tropospheric parameters are not consistent with the most recent analysis

encourages the EPN Special Project on Reprocessing to start the re-computations of the EPN in order to provide a long time span of consistent coordinates and tropospheric parameters.


Resolution no. 5

The IAG Reference Frame Sub-commission for Europe (EUREF)

recognising the advantage of combining gravity field parameters with geometric observations to stabilise geodetic reference systems

and considering

 –  the availability of the new realisation of the European Vertical Reference System EVRF2007 and the advanced status of the EUVN-DA project

 –  and the continuation of the EUREF project “European Combined Geodetic Network” (ECGN)

asks the TWG to contact the European Geoid Project in order to develop a combined European geoid to link ETRS89 and the EVRS.


Resolution no. 6

Considering the need for a wider understanding of EUREF products

and recognising the establishment of the “EUREF Working Group on the Future Development of ETRS89”

requests that the Working Group considers ways to foster the science and the methods employed by EUREF to a broader group of users.


Resolution no. 7

The IAG Reference Frame Sub-commission for Europe (EUREF)
