Deformation Analysis of Geodetic Networks by Applying M_split Estimation with Conditions Binding the Competitive Parameters

Abstract

In this paper, the use of the parameter estimation method in a split functional model in the analysis of geodetic network deformation is presented. Special attention is drawn to the situation when competitive parameters fulfill certain independent conditions in the systems of observation equations. It is also proposed that the so-called reversal-point effect can be eliminated from the Msplit estimation using conditional equations binding the competitive parameters. It is shown that the introduced extension of the Msplit estimation method does not deprive the studied method of its qualities, including its robustness.
