| Abstract: | The models and methods for combined treatment of coordinate data and tilt angle are focused on. Coordinate data of control points are obtained from total station. Trim and list are from by tiltmeters. At first, based on large angle coordinate transformation, the tilt data serves as observed data during the process of adjustment. The next step is to analyze the impact of different accuracies of tiltmeters and different layouts of common points. The model has been already validated in engineering examples. The result shows that the model can improve the accuracy and reliability of attitude. |
