ABSTRACT In a local area network for engineering purposes the external accuracy of different RTK techniques is analysed in detail. Three different solutions for the network are produced by varying the kind of the necessary reference station. First of all a local reference station resulting in very short baselines is used for the RTK-measurements. A second solution for the network is produced by using the nearest SAPOS reference station (SAPOS: Satellite Positioning Service of the German National Survey) resulting in an average baseline length of about 6.8km. At least so called virtual reference stations – derived from a network solution of the surrounding SAPOS-stations – are used for a third RTK-solution.
