Precise Estimation of the Geometrical Parameters of the Bam Fault Using Least Squares Method

Based on the improvement of the geodetic techniques for the observation of the fault mechanism, it became very important to determine the stability and accuracy of the measurements. Following the new technologies such as GPS and high quality observations, many studies on tectonic problems can be initiated and improved. However, the quality and reliability of data obtained and results deduced from these studies depend on the location of stations, in other words, the design of geodetic networks, measurements techniques and observation errors. The purpose of this study is the optimum designing for the geodynamic networks which estimates the most accurate values for the geometric parameters of the fault. For this scope, a simple and one dimensional model for a strike-slip fault is used and number of stations is fixed around the fault and it is assumed that we observe the deformations with these station positions correctly, and, using simulations, we checked the relationship between the accuracy of deformation model parameters based on errors (correlated noise and monument instability) and then investigate the sensitivity of the parameters according to the number of the stations and the distance from the fault.
