Sensitivity Optimization at the Densification GPS Networks for Monitoring Crustal Movements

Abstract

Densification GPS Networks must provide the precision and reliability requirements. At the same time, these networks should be able to detect the possible earth crust movements. If the total weight of observation at a point raises, the sensitivity capacity of the point increases with the same rate. However, controllability of these observations weakens relative to neighboring observations. This paradox is a fundamental design problem that it must be resolved in the evaluation phase of geodetic networks. In this study, an improvement strategy has been recommended as a solution to the design problem.
