The geodetic networks should be able to detect the possible earth crust movements caused by active tectonic movements in Turkey. Geodetic networks should also be able to determine the crust movements accurately as well as provide precision and reliability requests. The capacity of geodetic networks to determine the crustal movements can be determined by sensitivity analysis. Robustness analysis consists of strengthening internal reliability analysis with strain techniques. Robustness is defined as the deformation strength induced by the maximum undetectable errors with the internal reliability analysis. The robustness of a geodetic network is determined by the global initial condition, which aims at minimizing the total displacement value in the network. In this study, the local initial condition that aims to minimize the total displacement value at the uniform polyhedron, which consists of observations from each station points. The displacement values obtained according to the local and the global initial conditions are compared with threshold values. The results have also been interpreted.
