Unreferenced date April 2009 A geodetic network is a network of triangle s which are measured exactly by techniques of terrestrial surveying or by satellite geodesy . In classical geodesy up to the sixties this is done by triangulation , based on measurements of angle s and of some spare distances the precise orientation to the geographic north is achieved through methods of geodetic astronomy . The principal instruments used are theodolite s and tacheometer s, which nowadays are equipped with infrared distance measuring, data base s, communication systems and partly by satellite links. Electronics Electronic distance measurement EDM was introduced around 1960, when the prototype instruments became small enough to be used in the field. EDM increased network accuracy accuracies up to 1 1 million 1 cm per 10 km today at least 10 times better , and made surveying less costly. The geodetic use of satellite s began around the same time. By using bright satellites like Echo satellite Echo I , Echo II and Pageos , global networks were determined, which later provided support for the theory of plate tectonics . Another important improvement was the introduction of radio and electronic satellites like Geos Geos A and B 1965 70 , of the Transit satellite Transit system Doppler effect 1967 1990 &mdash which was the predecessor of GPS and of laser techniques like Lageos USA or Starlette F . Despite the use of spacecraft, small networks for cadastral and Technology technical projects are mainly measured terrestrially, but in many cases incorporated in national and global networks by satellite geodesy. Nowadays, several hundred geodetic satellites are in orbit, supplemented by a large number of remote sensing satellites and navigation systems like GPS and Glonass , which will be followed by the European Galileo satellite navigation Galileo satellites in 2013. While these developments have made satellite based geodetic network surveying more flexible and cost effective than its te ... more details
