Ivan I. Mueller

Ivan Istvan Mueller (* 9. January 1930 in Budapest ) is an American surveyor and emeritus professor at the Ohio State University , which is the most important training center for Geodesy is in the US.

Mueller has shaped satellite geodesy from its beginnings and in particular designed several projects for intercontinental networks of satellite triangulation , one of which is considered to be groundbreaking with the use of Doppler satellites (1973/74). It was combined with the world network of satellite triangulation by Hellmut Schmid (USA / Switzerland 1974) to provide the most precise determination of coordinates across all seas to date and achieved a standard deviation of around ± 3 m, which was around 20 times more accurate than the terrestrial methods that at that time required extremely lengthy measurements over island chains .

Among his many other ideas and projects, one should mention Satellite Laser Ranging (SLR), which was used to research the geodynamics of California. Mueller suggested that the laser - distance measurements not by numerous ground stations carry out, but an active laser satellites with runtime measurement to develop on board. This could result in significant savings and acceleration of the measurements. The idea turned out to be technically not yet feasible, but was adopted in a similar form around 1990 for the French DORIS Doppler measurement system.

In addition to being a top researcher, Mueller is also an excellent organizer and has received several honorary doctorates . He is a member of several scientific academies , including those of Austria and Hungary . He was also a leader in several courses at the International School of Geodesy ( summer schools ).
