On behalf if the conveners I would like to draw your attention to this session and encourage you to participate in it. We are developing a rich session that will showcase the improvements to the geodetic observing systems that are being planned or that are
currently underway. I hope that you will be able to join us in San Francisco for this exciting session. More<span style="background-color: rgba(255, 255, 255, 0); -webkit-text-size-adjust: auto; "> information about the 2016 Fall Meeting can be obtained from

<font face="Helvetica" size="3">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.</font></div>
