Черноус С. А. и др. Навигация GPS/ГЛОНАСС в Арктике и полярные сияния 812 S. A. Chernouss, I. I. Shagimuratov, B. A. Vulfovich, N. V. Kalitenkov avigation GPS/GLO ASS in the Arctic and aurora The correspondence of the time-spatial distribution of the radiances of the aurora oval and time-spatial changes in the parameters of the navigation satellites' signal has been shown. For this aim the experimental data on the regional and local heterogeneities of the Total Electron Content (or TEC) and the data on the signal delays in the polar ionosphere have been analyzed. Using the data concerning aurora as the indicator of disturbances in the work of the GPS/GLONASS systems can give the opportunity to increase considerably the accuracy of positioning in the Arctic with the help of satellite navigation systems (SNS). Key words: polar ionosphere, aurora oval, dynamics of oval, signal of navigation satellites, heterogeneity of electronic content, satellite navigation systems, accuracy of positioning.
