Karl Heinrich Ramsayer (29 September 1911, Schwäbisch Gmünd[1] – 24 December 1982, near Stuttgart) was a German geodesist and is well known as one of the most important scientists in geodetic astronomy and in electronic navigation.
Many patents in automatic positioning methods and air guidance systems have their origin in Stuttgart research projects.
Long series of NATO test flights showed the advantages of combining different positioning methods (integrated navigation).
In geodesy and geosciences, Ramsayer's priority was the integration of electronic and astronomic observation methods to improve the mutual quality and the strength of networks.
One of his major works late in life was volume IIa of the Handbuch der Vermessungskunde, published in 1968.
