CALL FOR PROPOSALS
for hosting the Central Bureau of the International Gravity Field Service

(with updated Proposal deadline)

INTRODUCTION

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 IGFS was established by the International Association of Geodesy Executive Committee at the IUGG General Assembly in Sapporo, Japan, August 2003, and is an IAG ‘level-2’ service under IAG Commission 2 – Gravity Field. One of the main arguments for establishing the IGFS was to provide a leading role of the gravity field services, as one of the three fundamental pillars in the IAG’s first project - GGOS, the Global Geodetic Observing System, which now is a major Component of the IAG.

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.

Another important role of the IGFS is to take new initiatives and coordinate international data collection projects, such as, e.g., Arctic and Antarctic Gravity and Geoid Projects, and the support of development of high and ultra-high resolution global geopotential models, such as NGA’s EGM08 and its evaluation.

The IGFS is not handling gravity field data distribution directly. The IGFS will function as a unifying service and contact for the following gravity field related services (IGFS Centres):

- BGI – International Gravimetric Bureau – collection, archiving, distribution of gravity data. Hosted by CNES, Toulouse.

- IGeS – International Geoid Service – collection and distribution of geoid models and related software, geoid schools – hosted by Politecnico di Milano.

- ICET – International Centre for Earth Tides – collection and archiving of global Earth tide data, including data from the Global Geodynamics Project – hosted by the University of French Polynesia.

- ICGEM – International Centre for Global Earth Models – distribution of satellite and surface spherical harmonic models – hosted by GFZ Potsdam.

- IDEMS – International DEM Service – provision of Global Digital Terrain Models – hosted by DeMontfort University, UK.

- IGFS Technical Centre – National Geospatial-Intelligence Agency, USA (G&G dept.) - advises on global models, geoid and gravity, supplementing other services .

The structure of the IGFS centres is shown in Figure 1, and can be seen on www.igfs.net.

Figure 1: Structure of the IGFS.

Current working groups under the IGFS include

· Working Group on Absolute Gravimetry - Standardization and Networks – chaired by H. Wilmes, BKG, Germany.

· Working Group on Evaluation of Global Earth Gravity Models, chaired by J. Huang, Geodetic Survey Division, Natural Resources Canada.

The IGFS held a Retreat in 2008, and has identified areas such as implementation of a new global vertical datum, coordination of repeated global absolute gravity measurements, and the unification of temporal satellite gravity field solutions, as potential future tasks for the IGFS.

The Role of the Central Bureau

Charter

2009 Tsuboi Prize of the Geodetic Society of Japan

Prof. Akito Araya of Earthquake Research Institute, the University of Tokyo has been awarded the 17th Individual Prize of the Tsuboi Prize, and ALOS/PALSAR InSAR observation group led by Dr. Masanobu Shimada of Japan Aerospace Exploration Agency has been awarded the 9th Group Prize.

The Tsuboi Prize of the Geodetic Society of Japan (Individual Prize) was established in 1993 to encourage young geodesists in Japan after the late Prof. Chuji Tsuboi who was one of the greatest geodesists in Japan. Since then, the prize winner has been awarded annually.

Prof. Akito Araya has been engaged in developing various geodetic instruments which utilize laser interferometry. In particular, a 100m laser strainmeter installed in Kamioka mine, which has extremely high sensitivity of 10^-13 strain, has been successfully utilized for the studies of the Earth tides, seismic strain steps and other geodynamic phenomena. He is also developing a new absolute gravimeter, a satellite on-board optical accelerometer. These works have proved his outstanding talents in the fileds.

Recognizing the importance of group organization in geodetic studies, the Group Prize was established afterward in 2001 and has been awarded to a group which has achieved outstanding contributions to geodetic studies.

Advanced Land Observation Satellite (ALOS) has been launched in 2006 and PALSAR (Phased Array type L-band Synthetic Aperture Radar) mounted on ALOS has been providing high quality SAR data. L-band SAR data provided by ALOS/PALSAR has advantages in particular in vegetated areas, and it has successfully revealed crustal movements associated with 2007 Noto Hanto earthquake in Japan, 2008 Sichuan Earthquake in China. Contributions of the group to developing and operating ALOS/PARSAR system have been highly recognized.

GOCE achieves drag-free perfection

Launched on 17 March and currently progressing through the commissioning phase, GOCE (Gravity field and steady-state Ocean Circulation Explorer) is set to measure Earth's gravity field with unprecedented accuracy.

GOCE was recently switched to drag-free mode as part of the commissioning and instrument calibration activities. The system was found to be working perfectly, demonstrating that the electric ion thruster-based control system automatically produces the right amount of thrust to achieve drag-free flight. This could not be demonstrated at ground level before GOCE launched since it is impossible to create exact in-orbit flight conditions in a laboratory.

Michael Fehringer, ESA's System Manager for GOCE said, "We were very pleased with the results when the ion propulsion system and the gradiometer, which is the main instrument, were commissioned separately a couple of weeks ago. Now, both systems work together flawlessly – the gradiometer continually senses the air drag and feeds the ion-propulsion system with commands to produce thrusts exactly opposite to the drag being experienced. Initial data indicate that this drag compensation system works 10 times better than what we had expected."

Rune Floberghagen, ESA's GOCE Mission Manager stated that, "Knowing that the drag-free control system works perfectly means we now have everything in place to carry out the complex process of calibrating the gradiometer instrument. Once calibration has been completed we will be able to see the true excellence of GOCE's gravity-field measurements."

Obituary

Kurt Bretterbauer (1929-2009)

On Feb 28^th 2009 o. Univ.-Prof. Dr. Kurt Bretterbauer passed away at the age of 80. K. Bretterbauer has chaired for more than 25 years the Institute of Advanced Geodesy at the University of Technology, Vienna, Austria. He was a well known and highly recognized scientist in the fields of geodesy, astronomy and mapping. K. Bretterbauer was an excellent teacher who formed generations of Austrian geodesy students and civil engineers. Furthermore he has been invited to numerous international meetings as key lecturer due to his vivid and always excellent presentations.

Kurt Bretterbauer was born in Vienna in 31^st Jan 1929. After the war he started in 1949 to study surveying at the ‚Technical High-School’ in Vienna where he received his diploma after 4 years. Afterwards he became employed at the BEV (Austrian Federal Office for Surveying and Metrology, Department Geodesy). Besides he studied mathematics and astronomy at the Vienna University.

In 1958 he received a grant which allowed him to join the Department of Geodetic Science of the Ohio State University from fall 1958 until end of 1959. This was a scientific extremely fruitful period and offered him the opportunity to make use of his fundamental knowledge in mathematics and astronomy in state of the art science projects e.g. the World Gravity Project or the mapping of the Moon’s surface.

Back in Vienna K. Bretterbauer kept his position at BEV for more than 8 years. In 1967 he became a research assistant at the Institute of Advanced Geodesy (Professor Ledersteger), where he finished his doctoral thesis about signal refractivity in 1970. In 1973 he was appointed as the chair of the Institute of Advanced Geodesy at TU-Vienna. Within the upcoming 25 years he guided the institute to become a leading research centre in reference systems, point positioning and mapping. Aside he held a number of high ranked administrative functions within the Austrian Geodetic Society like the Bureau of the Austrian Commission for International Geodesy or the Bureau of the National Committee of Geodesy and Geophysics.

The major fields of scientific interest of K. Bretterbauer were Earth rotation, reference systems and time scales, mapping theory and last but not least Global Change. So he was one of the first scientists who described early 1983 the consequences of a partial melting of arctic ice-sheets on potential surfaces and the Rrtation of the Earth. He delivered a considerably large number of scientific contributions investigating the change of the shape and rotational behaviour of the Earth from ancient times until today. Furthermore he promoted research in satellite geodesy and the application of astro-geodetic methods for point determination at the institute. Thus a zenith-camera to determine the deflections of the vertical has been constructed and a CCD-camera for the observation and determination of satellite orbits was developed. Moreover he anticipated the potential of the upcoming GPS-systems for geodetic and geodynamic research.

Kurt Bretterbauer was an excellent teacher and extremely gifted lecturer. He was able to simplify even very complex relations but always without loosing the general theory behind. He was a very appreciated partner in technical and philosophical discussions and he was able to fascinate and delight his audience with his sometimes extraordinary scientific ideas.

Despite of the already known disease over the past years Kurt Bretterbauer died unexpected by just a few weeks after his 80th birthday celebrations. He will be unforgotten as a friend and as a reliable and competent expert.
