geodetic astronomy वाक्य

The Polish seismologists include the geodetic computer scientist Zdzislaw Adamczewski from the Institute of Higher Geodesy and Geodetic Astronomy at Warsaw University of Technology.
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 ).
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.
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.
