Hellmut H. Schmid (12 September 1914 – 27 April 1998) was Professor of geodesy and photogrammetry on the ETH Zürich (Switzerland), where he emerited in 1985. In the 1950s, he worked on research projects of space exploration in the United States. Between 1968 and 1974, he promoted the first intercontinental network of satellite geodesy.


Focal points of his research in Europa

  • Geodetic measurement methods at the V2 projekt in Peenemünde (~1942)
  • Bbeginnings of satellite geodesy 1959
  • Theory of analytical photogrammetry and matrix/IT developments (1950s, USA)
  • High precision evaluation of photogram (ca. 1965-1978)
  • Worldwide Satellite Triangulation Network (1969-1973 (publ. 1974): first regular intercontinental network, 46 stations (3000–5000 km apart), pioneering accuracy (±3m)
  • Contributions to the method of least squares, network optimization, Block triangulation
  • Optimization of coordinate transformations (~1975)
  • Development of 3D intersection methods in analytical photogrammetry
