摘要
In 1993 a precise GPS network was established in the region of Tierra del Fuego. In 1998, a levelling line was measured with origin at Ushuaia tide gauge. Gravimetric measurements were also made to apply the orthometric correction. This line is not enough to obtain a geoid model from GPS observations at the levelling points, so during 2000, new levelling and GPS measurements were made following secondary roads to improve the distribution of the points. In this work, these results are presented and compared with geoid undulations calculated from EGM96 model.
