The method that is proposed in the present paper is a special case of squared Msplit estimation. It concerns a direct estimation of the shift between the parameters of the functional models of geodetic observations. The shift in question may result from, for example, deformation of a geodetic network or other non-random disturbances that may influence coordinates of the network points. The paper also presents the example where such shift is identified with a phase displacement of a wave. The shift is estimated on the basis of wave observations and without any knowledge where such displacement took place. The estimates of the shift that are proposed in the paper are named Shift-Msplit estimators.

Przedstawiona w pracy metoda jest szczególnym przypadkiem kwadratowej Msplit estymacji. Dotyczy ona bezpośredniej estymacji przesunięcia miedzy wartości parametrów występujących w funkcjonalnych modelach obserwacji. Takie przesuniecie (shift) może na przykład wynikać z deformacji sieci geodezyjnej lub innych nielosowych zakłóceń obciążających jej współrzędne. W pracy przedstawiono także przykład, w którym shift jest utożsamiany z przesunięciem fazowym fali. Przesuniecie to jest estymowane na podstawie pomiarów wartości fali, realizowanych bez informacji o punktach, w których takie przesuniecie występuje. Zaproponowane estymatory nazwano ogólnie Shift-Msplit estymatorami.
