Simulazione di reti GPS permanenti per il monitoraggio di fenomeni franosi: strategie e problematiche

The aim of this paper is the mathematical design of GPS permanent networks devoted to monitor different landslides located in the Italian area. First we evaluated the error budget due to the sistematic effects relevant for this kind of networks. Then we performed two different kinds of simulations, corresponding to two different situations: the «network solution», to verify the precision achievable during the landslides quiescence and the «single session» solution, to verify the precision achievable during the landslides activity. The results show different behaviours between the landslides whose points are «homogeneously» distributed with respect to the height and those where is even only one point with a height very different from the others.
