Additionally, covariance matrices were introduced to assess the accuracy of estimation results. The theoretical discussion includes an example of its application in a simulated, three-dimensional geodetic network. The obtained results encourage further, more detailed analysis of real geodetic networks.}, type={Article}, title={Properties and analysis of the accuracy of estimation results obtained by the DiSTFA method in monitoring displacements and strains}, URL={http://journals.pan.pl/Content/121230/PDF-MASTER/5_GK_VOL_58_NO_2009_Kaminski_W%C5%82asnosci.pdf}, keywords={displacements, strains, free adjustment, transformation, unstable reference system, covariance matrices}, }
