The Digital Zenith Camera - A New High-Precision and Economic Astrogeodetic Observation System for Real-Time Measurement of Deflections of the Vertical
During the last few years, new developments in the field of geodetic astronomy have been sparsely published. This might be due to the fact that the determination of deflections of the vertical still required relatively large efforts, both in time and in manpower, thus keeping the costs per point at a high level. Recently, the development of new high performance image sensors (CCD) at a reasonab...
متن کاملDigital Zenith Cameras – State-of-the-Art Astrogeodetic Technology for Australian Geodesy
Over recent years, significant progress has been made in astrogeodetic research with the development of digital zenith camera systems (DZCSs) at ETH Zurich, Switzerland, and the University of Hanover, Germany. The use of charged coupled device (CCD) sensors for star imaging improved the degree of automation, accuracy and efficiency of this modern astrogeodetic instrumentation. With DZCSs, verti...
متن کاملAstrogeodetic Validation of Gravimetric Quasigeoid Models in the German Alps - First Results
In regions with a rough topography, e.g. the European Alps, the accuracy of geoid or quasigeoid models is often reduced. For the validation and accuracy assessment of gravimetric models, astronomical levelling is a well-suited independent method. In a test area, located in the German Alps, a new astrogeodetic data set was acquired using the Hannover Digital Zenith Camera System. Vertical deflec...
متن کاملThe Use and Abuse of Vertical Deflections
This paper reviews the deflection of the vertical and its use and abuse in geodetic surveying. ‘Importantly, the deflection of the vertical in Australia will change by around 6” upon the implementation of the Geocentric Datum of Australia (GDA94). Therefore, for some applications, the deflection of the vertical may no longer simply be neglected in survey computations and adjustments. With the r...
متن کاملAn Improved Method for Dynamic Measurement of Deflections of the Vertical Based on the Maintenance of Attitude Reference
A new method for dynamic measurement of deflections of the vertical (DOV) is proposed in this paper. The integration of an inertial navigation system (INS) and global navigation satellite system (GNSS) is constructed to measure the body's attitude with respect to the astronomical coordinates. Simultaneously, the attitude with respect to the geodetic coordinates is initially measured by a star s...
