Dear Colleagues,<br>
<br>
As you may be aware, February 8 is the abstract deadline for the
REFAG2018 Symposium ("Reference Frames for Applications in
Geosciences") to be held at the COSPAR 2018, 42nd Scientific
Assembly, from July 15-21 in Pasadena, California, USA, as
COSPAR Scientific Event B1.2, officially co-sponsored by the
International Association of Geodesy. The REFAG2018 Symposium
description posted at <a class="moz-txt-link-freetext" href="http://www.cospar-assembly.org">http://www.cospar-assembly.org</a> is copied
below.<br>
<br>
We anticipate having 6 half-daily sessions during the week
assuming participation is similar to the level of previous REFAG
Symposia (held every 4 years). In addition, 4 half-daily
sessions at COSPAR2018 are anticipated for the Panel on
Satellite Dynamics Meeting (COSPAR Scientific Event PSD.1).<br>
<br>
Note that in this four-year cycle of IAG's structure, IAG
Commission 1 on "Reference Frames" is now addressing a very
broad variety of topics related to reference frames, including
(for example) relativistic geodesy, co-location using common
parameters in space, co-location using clocks and new sensors,
troposphere ties, next generation reference frames,
environmental loading effects, etc. We therefore would
especially encourage abstract submission from all of you working
with Commission 1, including the many subcommissions and their
working groups, joint study groups, and joint working groups.
Abstracts relating to reference frames are welcome from all
researchers irrespective of IAG affiliation. <br>
<br>

<br>
Thank you for considering your participation in Pasadena in
July. Note that COSPAR is hosted by Caltech and NASA's Jet
Propulsion Laboratory, and provides a great opportunity to visit
colleagues at both institutions.<br>

COSPAR-18-B2.1: REFERENCE FRAMES FOR APPLICATIONS IN GEOSCIENCES
(REFAG2018)<br>
Description<br>
<br>
“Reference Frames for Applications in Geosciences” (REFAG2018)
continues the quadrennial series of symposia of IAG Commission 1
“Reference Frames”, which is identical to COSPAR Sub-Commission
B2 “International Coordination of Space Techniques for Geodesy.”
Reference systems and frames are of primary importance for
research in the geosciences, satellite orbit determination,
precision navigation, as well as for practical applications in
geo-information. For the geosciences, precisely defined
reference frames are needed for an improved understanding of the
Earth's rotation and its gravity field, geocenter motion,
glacial isostatic adjustment, surface loading deformation and
global redistribution of water, sea level change with time,
tectonic plate motion and plate boundary deformation, the
earthquake cycle, and other crustal displacements. We solicit
presentations dealing with theoretical aspects and the practical
realization of reference frames, as well as their applications
in the geosciences. Further emphases of the session are on
global terrestrial and regional reference frames, celestial
reference frames, and the co-location of space geodetic
techniques on ground and in space. Additionally, we encourage
scientific reports from the many dedicated participants of IAG
Commission 1, its sub-commissions, and associated working
groups.<br>
