During 1999 – 2000 Italian expedition in Antarctica started a new Geodetic Program with the aim to extend Northward and Southward the existing GPS geodetic network for the crustal deformation control of northern Victoria Land. The network is named VLNDEF (Victoria Land Network for DEFormationn control).A network of 20 stations, spanning an area of 700 km northward and 300 km westward, with an average distance of 70–80 km, and covering the area from TNB to Pacific Ocean Oates Coast was established and surveyed. Because of some rather long baselines, the session duration was not less than 40 hours and network stations were connected to the GPS permanent stations of Terra Nova Bay Station (TNB1), McMurdo (MCM4) and Dumont DTJrville (DDU).VLNDEF project was made within the activity of GIANT (Geodetic Infrastructure of Antarctica) SCAR (Scientific Committee on Antarctic Research) Program. GIANT is being developed for several years with the goal to study the infrastructure and the geodynamics of Antarctica continent by the analysis of different geophysical and geodetic data, GPS (SCAR GPS Epoch campaigns) and permanent tracking stations, Gravimetry, VLBI, Remote Sensing and tide gauges. Moreover the geodetic activities are coordinates and finalised within the actions of ANTEC (ANTarctic NeoTECtonics) SCAR Group of Specialists.
