Geodezinio vertikaliojo tinklo klaidų analizė taikant skirtingus išlyginimo modelius

Abstract

There are different methods to estimate normal heights and to evaluate accuracy in geodesy. In this article we analyse adjective parameters and conditional equation by using vertical network adjustment procedure to eliminate levelling measurements systematic errors. Analysing the introducing effect of initial data errors to adjustment values and to accuracy of parameters, also arbitrary and non-arbitrary networks adjustment variants. Adjustment of networks is applied by the least-squares method, when there are estimate adjustment values and accuracy of parameters in co-variations matrix form.
