Dear Colleagues:

At the AOGS-AGU (WPGM) Joint Assembly in Singapore, August 13-17, 2012 there will be a session on the Application of New Technologies in Space Science. 
A description of the session is given below. This is an opportunity to review some of the newer technologies that are rolling back the frontiers in space geodesy, 
to hear plans for implementation, and to discuss the impact that these technologies are having on our understanding of the Earth environment. We hope that you 
will join us in Singapore and we encourage you to participate in this session. 

More information about the AOGS-AGUArial”> (WPGM) Joint Assembly can be obtained from its web site at <http://www.asiaoceania.org/aogs2012>.

Please note that the abstract submission deadline is March 12, 2012.

We look forward to seeing you at AOGS-AGUArial”>.

Best regards,

Mike

Application of New Technologies

style=”font-size:10.0pt;font-family:Arial”>New space and
ground technologies are having a major impact on our
understanding of the Earth and its global change. The
integration and combination of space techniques such as VLBI,
font-family:Arial”>SLR style=”font-size:10.0pt; font-family:Arial”>, style=”font-size:10.0pt; font-family:Arial”>GNSS style=”font-size:10.0pt; font-family:Arial”>, DORIS,
altimeters, space-borne gravity field measurements (GRACE,
GOCE), and InSAR have provided us with powerful tools to
measure and monitor details of Earth structure rotation,
gravity field, and mass distribution to unprecedented temporal
resolution and spatial accuracy. The geometric ground based
measurement techniques define the reference frame (IRTF) that
allows us to reliably measure change over time, space, and
evolving technologies and to map mm per year motions on the
Earth’s surface that may be related to natural hazards.
Altimeters are being used to map the topography of the sea
surface, relating information on ocean dynamic, currents, and
weather, and the surface of lakes to provide real-time
monitoring of water level. Measurements from the gravity field
satellites give us information of mass shifts which can be
related to effects from changes in hydrology and Earthquakes;
the combination of altimeters and gravity field mapping gives
us a powerful tool to monitor changes in the ice budget and
its predicted influence in sea level. With occultation
measurements available with style=”font-size:10.0pt;font-family:Arial”>GNSS style=”font-size:10.0pt;font-family:Arial”> and
Formosat-3/COSMIC missions we now have a synoptic tool for
weather, atmospheric and ionospheric research.

style=”font-size:10.0pt; line-height:115%;font-family:Arial”>These
measurements and the resulting data products contribute to a
broad range of Earth sciences. They are increasingly supported
by the ground-based networks in the Asia-Oceania region and
used by regional research organizations, often in cooperation
with the IAG (International Association of Geodesy) Services.
The IAG has established the Global Geodetic Observing Systems
(GGOS) to encourage the application of these techniques to
better understand the dynamics of the Earth and its impact on
society. 

style=”font-size:10.0pt; line-height:115%;font-family:Arial”>This
session welcomes practitioners of the relevant ground and
space technologies and those who develop and apply the data
products. Topics of the
session include the emergence and application of the new
technological developments as well as proposals for new
geodetic satellite projects and space missions. This

session solicits also presentations about ideas, scenarios and
simulation studies for future gravity field and altimetry
missions. Contributions
are welcome from purely theoretical considerations and
simulations to concrete technological realizations and the
presentation and interpretation of recent results.
