摘要

The definition, maintenance and improvement of space geodetic reference frames, as well as the transformations between each other, is a prerogative of several different observing networks organized by the International Association of Geodesy (IAG) which in 2003 created the Global Geodetic Observing System (GGOS). This paper is intended to give a description of the main observing techniques and technologies, as well as the most important results deriving from them.
