G06-2: Global geodetic infrastructure for Earth System Monitoring=

The Global Geodetic Observing System (GGOS) of the IAG provides measurement= s of the static and time-varying shape, orientation and gravity field of th= e Earth, using geodetic instrumentation located on the ground and onboard s= pacecraft. The deployment of the observing networks, technological developments, multi-technique integratio= n, and improvements in modelling capabilities have all led to geodesy being= able to provide critical contributions, both scientifically and for wide s= ocietal benefit. The refinement in the applications and use cases that depend on geodetic products, especi= ally in science areas concerned with global change (e.g. global water cycle= , sea level, climate change), or the monitoring and early warning of geohaz= ards, impose stringent requirements on the products provided by GGOS. What makes this all possible, i.e. the s= et of observatories, analysis, data and combination centres, and the human = resources involved, is what the United Nations Global Geodesy Centre of Exc= ellence calls the Global Geodesy Supply Chain. The infrastructure part of this supply chain, at the GGOS le= vel, is overseen by the GGOS Bureau of Networks and Observations.

Among the most prominent products of the geodesy supply chain are the vario= us reference frames (geometry, height, gravity) required to provide a commo= n link in space and time for scientific observations, as well as for applic= ations such as positioning and navigation on land, sea, air and space. Other than the constant upkeep and modernisat= ion of the geodetic supply chain, the increasing demands in precision, accu= racy and consistency make it paramount that any systematic errors within an= d between the techniques be identified and resolved, paving the way to the GGOS requirements of 1 mm and 0.1 mm/y= r (or equivalent). In this session, we solicit contributions on the infrast= ructure aspects of the global geodetic observing system, such as:
