geodetic astronomy

Geodetic astronomy is the application of astronomical methods into networks and technical projects of geodesy.

Introduction to Geodetic Astronomy (revised and updated printing)

Many national coordinate systems of Gauss-Krüger are defined by ED50 and oriented by means of geodetic astronomy.

It is a 2 second first-order theodolite and is typically used for primary and secondary triangulations, traversing and geodetic astronomy.

The subfield also indexes the following: Geodetic Astronomy, Space geodesy, Gravimetry, and geodetic methods for solving geodynamic problems.

His particular interest in astronomy was the definition and precise measurement of time, and he designed a highly accurate portable printing chronometer for use in geodetic astronomy, which was successfully marketed.

Robbins' scientific publications covered a wide field in Geodesy and Photogrammetry, with outstanding contributions to knowledge in Geodetic Astronomy and the design and development of the Chronochord (printing crystal clock).

In "classical geodesy" (up to the sixties) this is done by triangulation, based on measurements of angles and of some spare distances; the precise orientation to the geographic north is achieved through methods of geodetic astronomy.

Karl Ramsayer (29 September 1911, Schwäbisch Gmünd - 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.

His scientific achievements were recognised by the International Association of Geodesy which elected him Secretary of Section (Control Surveys) of the Association, and President of the Special Study Group on Geodetic Astronomy.
