Session 1: Permanent GPS arrays, current and future
Conveners: Yehuda Bock (UCSD; ybock@ucsd.edu), and Yuki Hatanaka (GSI; hata@gsi-mc.go.jp)
Recent developments in regional permanent GPS arrays allow accurate, rapid monitoring of crustal deformation with high temporal and spatial resolution, and open the door to a wide variety of other applications, for example, in Meteorology, Ionospheric Science, and Engineering. Outstanding problems in achieving the inherent sub-mm positioning resolution of GPS include local-scale effects such as monument instability, antenna phase center modeling, signal multipath and scattering, and network-scale effects such as tropospheric and ionospheric refraction and propagation of terrestrial reference frame errors. Improvements are being made in GPS instrumentation and other site hardware (e.g., antenna domes, antenna adapters), site calibration, monumentation, data communications, and GPS analysis and modeling algorithms to mitigate these effects. We welcome contributions that cover current and future developments in regional permanent GPS arrays and the prospects for further improvements in the accuracy, reliability, and timeliness of network products.

Session 2: GPS meteorology: atmospheric sensing with ground and space-based GPS receivers
Conveners: Bill Kuo (UCAR; kuo@ucar.edu), Mike Bevis (Hawaii Univ.; bevis@soest.hawaii.edu), Yoaz Bar-Sever (JPL; yeb@cobra.jpl.nasa.gov), Randolph Ware (UCAR; ware@ucar.edu), Nobutaka Mannoji (JMA; nmannoji@npd.kishou.go.jp), and Toshitaka Tsuda (Kyoto Univ.; tsuda@kurasc.kyoto-u.ac.jp)
Phase and amplitude variations induced in GPS signals by the lower and upper atmosphere can be observed from the ground and from space. Observed from the ground, GPS phase delays can be used to estimate integrated values of tropospheric moisture along each of the dozen or so ray paths to GPS satellites in view. Observed from space, GPS phase delays can be converted into refractivity profiles. Ground and space-based GPS data have great potential for mesoscale modeling and prediction. Other applications include correction of atmospheric effects in GPS geodesy, calibration of satellite radiometry, correction of synthetic aperture radar images for crustal deformation applications, climatology, hydrology, coastal meteorology, detection of scintillation associated with atmospheric turbulence in the lower troposphere. We welcome presentations on these and related topics.

Session 3: A new view of the tectonic deformations in the Pacific and Asia using space geodetic techniques (joint with APSG)
Conveners: Shui-Beih Yu (Academia Sinica; eayusb@ccvax.sinica.edu.tw), Jeff Freymueller (Alaska Univ.; jeff@giseis.alaska.edu), Takao Tabei (Kochi Univ.; tabei@cc.kochi-u.ac.jp), and Minoru Kasahara (Hokkaido Univ.; mkasa@eos.hokudai.ac.jp)
The Asia-Pacific region includes many active plate boundaries, including the broad India-Eurasia plate collision zone and several continental margins - island arc systems. These plate-boundary deformation zones are the focus for geodetic studies because large deformation signals are expected over a range of spatial and temporal scales. Furthermore, hazards from geophysical events affect large numbers of people and infrastructures in the region. This session will focus on new insights into the kinematics of the deformation zones in the Asia-Pacific region derived from recent space geodetic measurements. Topics of particular interest include: (1) plate coupling and interaction at plate boundaries, (2) new definitions of tectonic blocks in the region, (3) processes of strain accumulation and release in the earthquake cycle, (4) monitoring of volcanic activities, and (5) motions along major active faults.

Session 4: Determination and interpretation of global and regional plate motions deduced from space geodetic techniques
Conveners: Kristine Larson (Univ. Colorado, kristine@colorado.edu), and Kosuke Heki (NAO, heki@miz.nao.ac.jp)
For this session we seek contributions concerned with the determination of global plate motion using space geodetic techniques such as GPS, VLBI, SLR, DORIS. Scientific discussions may focus on such topics as comparisons with time-averaged plate motion models and between different techniques, significance of vertical signals in global solutions, and large-scale internal deformation of tectonic plates. We also welcome contributions on the definition of new tectonic blocks and regional-scale crustal deformation studies in non-Asia-Pacific regions.

Session 5: Combination of space geodetic techniques for global dynamics and reference frames
Conveners: Thomas Herring (MIT, tah@mit.edu), Zuheir Altamimi (IGN, altamimi@ensg.ign.fr"), Shigeru Matsuzaka (GSI, shigeru@gsi-mc.go.jp), and Yukio Takahashi (CRL, takahashi@crl.go.jp) ... Convener changed
The combination of measurements from multiple geodetic systems allows the development of a unified terrestrial reference frame to support tectonic, geodynamics, and Earth rotation studies. Comparison of results from different techniques permits the assessment of systematic errors in each system, and the analysis of possible common non-modeled signals. Papers are sought that address the combination of data and results from VLBI, SLR, GPS, GLONASS, DORIS, and PRARE both in the form of parametric combinations and analyses at the observable level.

Session 6: Space and terrestrial techniques for advanced crustal deformation research
Conveners: Will Prescott (USGS; wprescott@usgs.gov), Frank Webb (JPL; fhw@jpl.nasa.gov), Seiichi Shimada (NIED; shimada@geo.bosai.go.jp), and Takeshi Matsushima (Kyushu Univ.; mat@sevo.kyushu-u.ac.jp)
This session will focus on the results of crustal deformation observations by GPS, InSAR and other terrestrial techniques such as trilateration, leveling, tiltmeter, strainmeter, creepmeter, water level, extensometer measurements, and so on. Such high precision space techniques, combined with terrestrial techniques, are required for monitoring earthquakes, volcanoes, post-glacial rebound, and other agents of change that produce crustal deformation. Presentations of new findings of crustal deformation observations are especially welcome.

Session 7: Application of GPS for monitoring Earth's environmental and global sealevel change
Conveners: Erik R. Ivins (JPL; eri@scn1.jpl.nasa.gov), and Yoshiaki Tamura (NAO; tamura@miz.nao.ac.jp) ... Convener changed
The Earth's environment is affected by human activities on a global scale. Monitoring the environmental changes in sealevel, ground water, ice-sheet volume, and Earth rotation are required across a variety of spatial and temporal scales. This session highlights the application of GPS to monitoring global environmental changes. Topics on monitoring sealevel, vertical datum realization, observations in Antarctica, etc., are welcome.

Session 8: Application of GPS for ionospheric research and impact of solar maximum for GPS measurements
Conveners: Richard Langley (Univ. New Brunswick; lang@unb.ca), and Akinori Saito (Kyoto Univ.; saito@kugi.kyoto-u.ac.jp)
This session will deal with the results of ionospheric research using the GPS/GLONASS systems, and the ionospheric effects on these positioning systems, especially during the upcoming solar maximum. Topics of the session include: (1) TEC variations associated with geophysical activities, such as geomagnetic storms and solar events, (2) effects of ionospheric irregularities on the GPS systems and techniques to mitigate these effects, (3) ionospheric tomography, including occultation observations, (4) comparison of GPS observations with ionospheric models or other observations using radar and optical measurements.

Session 9: Modeling of the crustal process based on GPS measurements
Conveners: Paul Segall (Stanford Univ.; segall@pangea.stanford.edu), Manabu Hashimoto (Kyoto Univ.; hasimoto@rcep.dpri.kyoto-u.ac.jp), and Takeshi Sagiya (GSI; sagiya@gsi-mc.go.jp)
The recent deployment of dense arrays of continuous GPS stations gives new insights into the spatio-temporal variations in crustal deformation and plate motion, and may result in a paradigm shift in our understanding of the physical processes in the Earth. In addition, computational methods and tools are also rapidly developing, which may solve some of the mysteries in Earth science, such as seismic coupling, seismic cycle, etc. This session welcomes papers related to the modeling of crustal deformation and plate motion, including data assimilation techniques, and numerical modeling.

Session 10: Theory and Methodology of GPS and other space techniques
Conveners: Peter Teunissen (Delft Univ. Tech.; P.J.G.Teunissen@geo.tudelft.nl), and Peiliang Xu (Kyoto Univ.; pxu@rcep.dpri.kyoto-u.ac.jp)
The aim of this session is to exchange ideas on theoretical and methodological aspects of the GPS and other space techniques (GLONASS, GNSS, and SAR) for precise positioning. Papers on methods for improved functional and/or stochastic modeling, including those of estimation and validation are especially welcome. This includes topics such as data quality assessment theory and stochasticity, bias reduction techniques (atmosphere, multipath, etc.), integer ambiguity resolution (GPS/GLONASS), phase unwrapping (SAR), statistical testing and quality control.

Session 11: Kinematic application of GPS technology to Earth sciences
Conveners: Oscar Colombo (NASA/GSFC; ocolombo@olympus.gsfc.nasa.gov), and Tetsuichiro Yabuki (STA; tyabuki@cue.jhd.go.jp)
Topics appropriate to this session are those applications of kinematic GPS (both real-time and post-mission) that may enable a more precise and effective use of scientific remote-sensing from moving platforms, such as laser and radar airborne terrain-mapping (including SAR and InSAR), photogrammetry, use of buoys for tidal and oceanographic mapping, hydrographic charting with airborne laser depth-sounders, and multi- beam and interferometric sonar.

Session 12: Issues of data quality management and hardware/software technological problems in GPS
Conveners: James L. Davis (Harvard-Smithsonian Center for Astrophysics; jdavis@cfa.harvard.edu), Peng Fang (UCSD; pfang@pgga.ucsd.edu), and Akio Yasuda (Tokyo Univ. Mercantile Marine; yasuda@denshi.tosho-u.ac.jp)
This session intends to address any technical issues that may bring about improvement in achieving the scientific objective of extracting the highest quality through reliable and efficient data collection procedures and data processing schemes. Contributors are encouraged to present innovative methods that overcome hardware or software limitations. New designs in quality control and data management are also welcome.

Session 13: GPS for gravity field and geoid determination
Conveners: Rene Forsberg (KMS; rf@kms.dk), and Yoichi Fukuda (Kyoto Univ., fukuda@kugi.kyoto-u.ac.jp)
This session seeks to address the impact of kinematic GPS in gravity field determination through airborne and shipborne gravity measurements, satellite GPS for gravity field recovery, and the use of GPS for geoid and height determination on both regional and continental scales.
