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. </font></font><font

is copied below.<br>
</font></font></font></font></p>
<p><font size="-1"><font face="Helvetica, Arial, sans-serif">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. </font></font><font size="-1"><font

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>

<p>“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.</p>
