This article studies the Optimal Biased Kriging (OBK) approach which is an alternative geostatistical method that gives up the unbiasedness condition of Ordinary Kriging (OK) to gain an improved Mean Squared Prediction Error (MSPE). The system of equ

Modifying Cadzow's algorithm to generate the optimal TLS-solution for the structured EIV-Model of a similarity transformationIn 2005, Felus and Schaffrin discussed the problem of a Structured Errors-in-Variables (EIV) Model in the context of a parame

Geodetic surveying practices require the establishment of new control stations that are tied to higher order stations with known coordinates (reference control stations – fiducial stations), an activity known as densification. The coordinates of th

Adjustment of geodetic data using coordinate-based formulations leads to rank-deficient Gauss-Markov models depending on the observation type. Among alternatives, minimum norm least squares solution (equivalently BLUMBE) is used to overcome this defi

In this study, we formulate two different approaches that will enable us to detect and control inconsistencies when integrating heterogeneous data sets. Through two numerical examples with simulated and real data, we compared both model solutions wit

The modeling of double-difference GPS phase observations for short baselines leads to the condition that the ambiguity parameters must be integers as long as residual biases can be neglected. However, not always is the combination of those integers t

It is well known that Tikhonov’s regularization method for ill-posed problems has a direct correspondence to certain predictors in the context of random effects models. Hence not only the iteration scheme of King/Chillingworth (1979) or E. Schock (
