Simulation and Adjustment of 3D (Three-Dimensional) Networks in the Concept of Integrated Geodesy

摘要

The principles of integrated geodesy are outlined, and the simulation program AREPO is described. The integrated concept is used to determine 3D coordinates of points on Earth and the Earth's gravity field, from a combined adjustment of heterogeneous data. Least squares collocation with parameters is used to solve for the required unknowns. The adjustment of observations simulated by AREPO shows that the collocation method produces good solutions.
