GGOS: A Long and Strong International Collaboration in Geodesy

Modern Geodesy should be viewed from the global perspective and efforts of all branches of this science should be bundled to serve one and the same goal: the scientific understanding of the System Earth to address societal challenges. Discover…

A Modern Network of Geodetic Sensors for the Observation of the Earth

The wide-range of signals emitted by changes in the System Earth are not detectable by a single measurement technique. While positioning techniques (VLBI, SLR, GNSS, DORIS) have demonstrated be an efficient tool to determine the kinematics of…

High and Consistent Performance through Standardisation

Different geodetic sensors register different System Earth signals. To produce an integral and global picture of this System, all geodetic observing techniques and analysis methods should be brought together consistently. The same standards,…

Geodetic Space Weather Research

Space weather describes physical processes mainly caused by the Sun’s radiation of energy in the magnetosphere, ionosphere, thermosphere, and exosphere. Severe space weather events have strong damaging impacts on modern society. They can for…

GNSS Enhanced Tsunami Early Warning System

Geodetic observations have a clear role in helping to reduce the risk of disasters, as well as contribute to disaster preparedness with better mitigation and response. The GGOS Focus Area “Geohazards” successfully submitted content for the…

Satellite Laser Ranging School

,
Prior to the 2019 ILRS Workshop, the ILRS scheduled a one-day introductory course to give non-practitioners in SLR an opportunity to broaden their knowledge about laser ranging to Earth-orbiting satellites and the Moon. The course also provided attendees with some experience in the field an opportunity to refresh and strengthen their knowledge and increase their appreciation of this powerful measurement technique that supports geoscience and applications.

Report on the ILRS Technical Workshop 2019

,
This year’s International Laser Ranging Service (ILRS) Technical Workshop was hosted by German Aerospace Center (DLR) in Stuttgart, Germany, from October 21st to 25th. Following the motto “Laser ranging: To improve economy, performance, and adoption for new applications” the presentations were focused on the technical challenges for the satellite laser ranging (SLR) ground segment.

IAG ICC on “Geodesy for Climate Research”

, ,
During the IUGG General Assembly in Montreal the IAG Executive Committee (EC) established a new IAG Inter-Commission Committee on "Geodesy for Climate Research" (ICCC) to enhance the use of geodetic observations for climate studies. The goal is to establish a systematic and comprehensive approach among the various geodetic communities, but also to establish and foster links to climate science.
