Positioning with astronomic and geodetic method
Yilmaz, Nazan and Celalettin Karaali
Geodesy is a science whose goal is to determine the whole or part of earthhs shape. To determine its shape in other words to be showed in a coordinate system, we must obtain information with observations at proper points which are on physical surface. Among the information, there is also information obtained from astronomical observations which are done to celestial bodies. Geographical positions of earthhs points can be obtained both astronomic and geodetic. Astronomic latitudes and longitudes ) , ( Λ Φ are achieved by astronomic observations. Geodetic latitudes and longitudes ) , φ ( λ are geographical coordinates relating to be chosen ellipsoid and today they can be achieved by GPS technology easily. Satellite based positioning technique GPS is widely used in engineering measurements and practical geodetic applications. In this study, astronomic observations and GPS observations have been done in 7 points of a network with 17 points which has been established in the campus area of Karadeniz Technical University. So, both astronomic and geodetic latitudes longitudes have been determined in these 7 points. In addition, astronomic and geodetic latitude longitude values which belong the same points have been compared by each other.
