Abstract

A two series of the global and national normal heights has been used for determination of geopotential W0 of a local geoid. This scientific articale presents results of using of a met-hod of mathematical processing of double meassurements for detecting and correcting sys-tematic error in above mentioned two series and proposes criterion for determination of erroneous series. Experiment results on the 17 co - located GPS observations first order benchmarks showed effectivity of researched method.
