Session ID#: 16158

Session Description:
The Global Geodetic Observing System (GGOS) provides measurements of the time varying gravity, rotation, and shape of the Earth using geodetic and gravimetric instruments located on the ground and in space. These measurements need to be accurate to better than a part per billion in order to advance our understanding of the underlying processes that are causing the Earth's rotation, gravity, and shape to change. Mass transport in the global water cycle, sea level and climate change, and crustal deformation associated with geohazards are examples of particularly demanding applications of geodetic and gravimetric measurement systems. Designing and deploying the ground and space-based instruments that are needed to provide geodetic and gravimetric measurements of the accuracy and stability required are an ongoing challenge for GGOS. This session will be a forum for discussing the current status and future plans of the evolving ground and space-based geodetic and gravimetric measurement systems.
