SUMMARY:United Nations Global Geodesy Forum
DESCRIPTION:[vc_row][vc_column][vc_column_text] \nGlobal Geodesy Forum\nEvery day\, humanity benefits from geodesy. Geodesy is the science of measuring the size\, shape and orientation of our planet and it is a foundation for evidence-based policies\, decisions and program delivery. Geodesy is used every day\, in the fields of civil engineering\, industrial automation\, agriculture\, construction\, mining\, financial transactions\, intelligent transport systems\, disaster response and emergency management\, environmental studies and scientific research. Furthermore\, geodesy enables accurate collection\, management and alignment of nationally integrated geospatial information – a key requirement for societal\, environmental and economic activities\, the measuring and monitoring of progress of the 2030 Agenda for Sustainable Development\, the Sendai Framework for Disaster Risk Reduction\, the Small Island Developing States Accelerated Modalities of Action (SAMOA) Pathway\, and other global\, regional and national development agenda and initiatives. \nThe United Nations Global Geodesy Forum appropriately convened on Earth Day – 22 April 2021 with the title “The Power of Where: The Value of Geodesy to Society”. The virtual open forum organized by the Subcommittee on Geodesy will focus on the significance of geodesy for the wellbeing and betterment of society\, environment and economy. The forum will highlight to policy- and decision makers\, chief executives\, director-generals and senior executives from Member States and relevant stakeholders the benefits enabled by an accurate and reliable Global Geodetic Reference Frame\, and the crucial role of geodesy in providing safer and more resilient communities\, in particular\, to measure the cause and effect of sea level rise\, storm surges\, earthquakes and tsunamis\, and assisting developing countries with effective land and environmental management and efficient digital economies. \nThe United Nations Secretary-General’s Special Envoy for the Ocean\, His Excellency Ambassador Peter Thomson\, who is also the Global Geodesy Ambassador\, will provide the opening address. \n  \nVisit the Global Geodesy Forum event page to learn more.[/vc_column_text][/vc_column][/vc_row]

SUMMARY:IGS Session - Orals
DESCRIPTION:[vc_row][vc_column][vc_column_text] \nAbout this Session\nThe International GNSS Service (IGS) provides the scientific community with a broad range of high-precision products supporting a wide diversity of scientific applications. Currently three fully-deployed GNSS are analyzed by IGS Analysis Centers and included in the currently running reprocessing effort: GPS (USA)\, GLONASS (Russia)\, and Galileo (Europe). Developments including additional GNSS (Chinese BeiDou\, Japanese QZSS\, Indian NavIC\, etc.) are ongoing within the IGS. \nSeveral components of the IGS do already support a fully consistent processing of GPS\, GLONASS\, and Galileo in the operational chain as well as for the currently running reprocessing effort.  The continuous improvement of IGS products in this fast-moving field – with constantly evolving satellites\, systems\, signals\, models\, and data analysis methodology – is a scientific challenge. \nThis session solicits presentations on scientific applications enabled by IGS products and new science enabled by improvements to quality and breadth of GNSS products.[/vc_column_text]VIEW SESSION [/vc_column][/vc_row]

DESCRIPTION:[vc_row][vc_column][vc_column_text] \nAbout this Session\nThe quantification of many geophysical phenomena\, e.g. sea level variation\, co-and post-seismic deformation\, glacial isostatic adjustment\, loading effects\, but also precise orbit determination of artificial satellites\, rely on the availability of a global terrestrial reference frame\, such as the ITRF. The session solicits contributions from scientists determining or using global reference frames for their applications\, focusing on error budgets and other limiting factors. Contributions from analysts of space geodetic techniques (VLBI\, SLR\, GNSS\, DORIS) and their combination in preparation for the ITRF2020\, taking into account improved model updates are welcome.

SUMMARY:GGOS Session - Orals
DESCRIPTION:[vc_row][vc_column][vc_column_text] \nAbout this Session\nThe 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 measurements. All these measurements require a common reference with the same precision\, like the Terrestrial Reference Frame and the Unified Height System. \nThis session provides a platform for discussing diverse scientific targets of GGOS with large dynamic ranges in space and time and geodetic infrastructure to enable stable production of accurate data.[/vc_column_text]VIEW SESSION [/vc_column][/vc_row]
