The Global Geodetic Observing System: Geodesy for Science and Society
The Global Geodetic Observing System: Geodesy for Science and Society
Session ID#: 118642
Session Description:
The Global Geodetic Observing System (GGOS) provides measurements of the
time varying gravity, rotation, and shape of the Earth using space and
terrestrial geodetic techniques. These measurements must be accurate
to better than a part per billion in order to advance our understanding
of the underlying processes responsible for temporal changes in the Earth's
rotation, gravity, and shape. Demanding applications of geodesy include
mass transport in the global water cycle, sea level
and climate change, and crustal deformation associated with geohazards.
All these measurements require a common reference with the same precision,
like the Terrestrial Reference Frame and the Unified Height System. GGOS
is designed to unite the individual observations and model into one
consistent frame with the highest precision available to be realized as
Global Geodetic Reference Frame (GGRF). This session welcomes contributions
on general GGOS topics, particularly those related to scientific and social
aspects of GGOS applications.
