1st Workshop on Data Science for GNSS Remote Sensing
2022-06-13 - 2022-06-15 | GFZ Potsdam, Telegrafenberg, Potsdam, 14473, Germany
There has been recently a rapid progress in Earth observation using GNSS signals from numerous ground and satellite based platforms as well as modern data scientific approaches for their analysis, including machine learning and data assimilation techniques. We believe it is the right time to gather scientists interested in interdisciplinary activities linking these two research areas to foster a creative and intense scientific exchange and collaborations. Our ultimate goal is the provision of advanced and versatile GNSS Remote Sensing data products on different spatio-temporal scales for Earth System science and related operational applications to advance early warning systems and numerical weather forecasts.
This meeting will be hosted by the German Research Centre for Geosciences GFZ and will take place on the historic “Telegrafenberg” in Potsdam on June, 13-15, 2022. At the moment, it is planned as a face-to-face meeting. However, the organizers carefully observe the pandemic situation and will adapt the meeting format accordingly.

GGOS has its own session at the next EGU General Assembly 2022. Be aware, that the dates of EGU GA 2022 was moved from begin of April to 23-27 May 2022.
More information will follow …

The Global Geodetic Observing System: Geodesy for Science and Society
The Global Geodetic Observing System (GGOS) provides measurements of the time varying gravity, rotation, and shape of the Earth using space and terrestrial geodetic techniques. These measurements must be accurate to better than a part per billion in order to advance our understanding of the underlying processes responsible for temporal changes in the Earth’s rotation, gravity, and shape. Demanding applications of geodesy include mass transport in the global water cycle, sea level and climate change, and crustal deformation associated with geohazards. All these measurements require a common reference with the same precision, like the Terrestrial Reference Frame and the Unified Height System. GGOS is designed to unite the individual observations and model into one consistent frame with the highest precision available to be realized as Global Geodetic Reference Frame (GGRF). This session welcomes contributions on general GGOS topics, particularly those related to scientific and social aspects of GGOS applications.

Global Geodesy Forum - The Power of Where
2021-04-22 10:30 - 12:00
The Value of Geodesy to Society
Every 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.
An amazing panel of speakers will present the benefits of geodesy to society in a virtual open forum on Earth Day, the 22 April 2021, starting at 10.30 am (UTC).
The Global Geodesy Forum “Power of where: The value of Geodesy to Society” is organized by the UN-GGIM Subcommittee on Geodesy and will focus on the significance of geodesy for the wellbeing and betterment of society, environment and economy.

Global Geodesy Ambassador
The United Nations Secretary-General’s Special Envoy for the Ocean, the Honorable Ambassador Peter Thomson, who is also the Global Geodesy Ambassador, will provide the opening address. Ambassador Peter Thomson from Fiji introduced the resolution ‘A Global Geodetic Reference Frame for Sustainable Development’ (A/RES/69/266) to the United Nations General Assembly in 2015.
Crucial role of geodesy
The forum will also highlight the benefits enabled by an accurate and reliable Global Geodetic Reference Frame (GGRF), and the crucial role of geodesy in providing safer and more resilient communities. Target groups are policy- and decision makers, chief executives, director-generals and senior executives from Member States and relevant stakeholders in the global geospatial community. If decision makers and donors do not understand the value of an investment in the GGRF, they are unlikely to prioritize GGRF investments above other initiatives

GGOS Session:
G022 – The Global Geodetic Observing System: Resilient Infrastructure for Sustainable Scientific Activities I
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 measurements. All these measurements require a common reference with the same precision, like the Terrestrial Reference Frame and the Unified Height System. This 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.
This year the GGOS Session was held online. All contributions (pre-recorded oral presentations and posters) were available for registered AGU participants over the whole time from 1-17 December. GGOS Session Infos & Schedule
