By combining individual components with intelligent analytical algorithms, modern measuring systems such as robot tacheometer or the Global Positioning System, (GPS) allow many new areas of application in modern engineering surveying. Use of this equipment is initially limited to static, quasi-static or stop-and-go techniques. Today, these efficient measuring sensors are used increasingly for kinematic measuring tasks. Different applications for the precise description of the movement track and for optimizing the horizontal and vertical availability require a combination of these measuring sensors, which operate separately. Normally both these measuring instruments cannot be combined without changing hardware or software (firmware) This thesis presents a method that allows a synchronization of independent measuring systems without a common basis through a comprehensive observation of all factors of disturbance and influence. Calibration of terrestrial and global measuring sensors for kinematic applications is also discussed in detail. With respect to the description of dynamic movement processes, a calibration of this kind of kinematic measuring sensors requires an expansion of conventional geodetic strategies. Based on static characteristics, these sensors must be tested using kinematic testing methods relating to the type, size and behaviour of target points affected by measuring uncertainty. In addition, the real time capability of the measuring system and the synchronization of individual subsystems must be verified and, if required, minimized by corresponding calibration functions. The result is a hybrid measuring system for kinematic applications that, independent of the type of movement, allows a precise derivation of the movement path based on discrete measuring points on a millimeter scale. For example, these hybrid measuring systems can be employed for the following: as a high precision positioning system for navigation and control of process flows in road and railways track construction (machine guidance), for special applications involving maximum availability and accuracy requirements for land and water vehicles or aircraft, as a reference system to verify the feasible accuracy of positioning and application techniques, and to analyze technical reaction times of partial and overall systems in the precision farming sector. The descriptions of selected applications in this thesis are limited to testing of section specific land use with the Landwirtschaftlichen BUS System LBS, (DIN 9684 and ISO 11783) with respect to position accuracy, precision, quality, and size of disturbances occurring. Investigations have been partly funded by a joint research project within the Forschungsverbund Agrarökosysteme München, (FAM) research alliance, which took place at the Chair for Geodesy in cooperation with the Department for Bio Resources and Land Use Technology, Crop Production Engineering (both at the Technical University of Munich).
