The International GNSS Service (IGS) is an international activity involving more than 200 participating organisations in over 80 countries with a track record of one and a half decades of successful operations. The IGS is a service of the International Association of Geodesy (IAG). It primarily supports scientific research based on highly precise and(More)
Preamble A proof of concept for the International Global Positioning System (GPS) Service for Geodynamics (IGS) was conducted with a three-month campaign during June through September 1992, and continued until December 1993 as a Pilot-Service until the establishment of the IGS as a service of the International Association of Geodesy (IAG). The IGS formally(More)
a PhD in Satellite Geodesy in 1980. Chris is currently the Head of the School of Surveying and Spatial Information Systems at UNSW, where and he established in the early 1990s the Satellite Navigation and Positioning group, today the premier academic GPS and wireless location technology R&D laboratory in Australia. Chris is the Vice President of the(More)
Modern geodetic observations from a wide range of space and terrestrial technologies contribute to our knowledge of the solid Earth, atmosphere, ocean, cryosphere, and land water storage. These geodetic observations record the " fingerprints " of global change processes and thus are a crucial independent source of high accuracy information for many global(More)
The primary aim of this study was to investigate the functional neuroanatomy of motor planning, initiation and execution in a cohort of young adults (mean age 20 years) who were born very preterm (VPT; <33 weeks of gestation), as these individuals are at increased risk of experiencing neuromotor difficulties compared to controls. A cued motor task was(More)
Geodetic observations are necessary to characterize highly accurate spatial and temporal changes of the Earth system that relate to sea-level changes. Quantifying the long-term change in sea-level imposes stringent observation requirements that can only be addressed within the context of a stable, global reference system. This is absolutely necessary in(More)
