Pageos had a diameter of exactly foot (m), consisted of a mil (µm ) thick mylar plastic film coated with vapour deposited aluminium enclosing a volume of cubic foot (m3) and was used for the Weltnetz der Satellitentriangulation (Worldwide Satellite Triangulation Network) – a global cooperation organized by Hellmut Schmid (Switzerland & USA) 1969-1973. Finished in 1974, the network connected 46 stations (3000–5000 km distance) of all continents with an accuracy of 3–5 m (approx. 20 times better than terrestrial triangulations at that time).
