Overview

Geodesy is the science of mathematically determining the size, shape and position of the earth and the nature of the earth’s gravity field. Geodynamics is a subfield of geophysics dealing with dynamics of the Earth that applies physics, chemistry and mathematics to the understanding of how mantle, convection leads to plate tectonics and geologic phenomena such as seafloor speeding, mountain building, volcanoes, earthquakes, faulting and so on. The department provide PhD program in Geodesy that covers mathematical geodesy, physical geodesy, satellite geode­sy, processing and analysis of measurements, and geo-informatics. Both the theoretical and practical aspects of geodesy are considered. In addition, it also prepares and offer training to the scientific society on the related science with the department goal and mission. Finally, the department works different scientific researches mainly focus on the thematic area of the department as well as the institute that have a great role to the economic and development of the country. The department work different projects in collaboration with the other government and non-governmental institute like GII and MoWIE etc as well as within the ESSTI like Remote Sensing Research and Development Department and High Computing Directorate etc. Scientific activities of the department is mainly con­centrate on geodetic monitoring and analysis of global, regional and local geodynamic pheno­mena, precise positioning by combinations of various geodetic techniques, precise geoid de­termination, metrology and data processing. In the future, the department research area will be supported by an observatory for satellite and space geodesy and geodetic astronomy, a laboratory for geo-informatics, a laboratory for metrology in geodesy, and a reference geodynamic control station in Addis Ababa and Main Ethiopian Rift, inclu­ding a permanent GPS station and reference marks for absolute and relative gravity mea­surements (found in AAU-IGSSA).
