Experimental observations of carrier phase acceleration in conditions of polar ionosphere

Abstract

The paper presents a comparative analysis of the quality of measuring the phase carrier of signals from GLONASS and GPS navigation satellites and spectrum of small-scale irregularities of electron density in conditions of a nonstationary and inhomogeneous polar ionosphere. It is shown that small-scale irregularities of the electron density in the ionosphere can lead to a substantial nonstationary increase in the acceleration of the phase carrier of both GPS and GLONASS by a factor of 1.3–2.5 from the background level.
