[SGD01-01] The Global Geodetic Observing System (GGOS) - its Role and its Activities
Keywords: Space Geodesy, VLBI, SLR, GNSS, Gravity , Co-located geodetic measurements
GGOS advocates for implementation of core and co-location network sites to satisfy GGOS requirements, monitors the present state of the networks and projects their future status, and supports and encourages maintenance and improvement in the infrastructure critical for the development of data products essential to GGOS.
GGOS is focused on the IAG Services and the products they derive on an operational basis for Earth monitoring making use of various space geodetic observation techniques such as VLBI, SLR/LLR, GNSS, DORIS, altimetry, gravity satellite missions, etc. GGOS builds upon existing observing and processing systems of the IAG, supporting its goal of obtaining products of highest possible accuracy, consistency, and temporal and spatial resolution, which should refer to a consistent reference frame, stable over decades in time. To achieve these important IAG goals, GGOS supports the fundamental requirement that common standards and conventions are used by all IAG components for the analysis of the different geometric and gravimetric observations.
In this talk, we will discuss the role of GGOS, its current status and structure, and plans as we move forward.
