GLONASS

GPS signal jamming effect in Svalbard Island and its elimination by using GLONASS, Galileo and Beidou satellites

The Svalbard Islands are located in the Arctic Ocean, halfway between Norway and the North Pole. Because of this, the Svalbard Islands exhibit a number of special properties that make it an interesting region for studying interactions between the atmosphere, sea ice, and ocean. In this study, satellite signals of three points (NABG, NYA2 and NYAL) on the island of Svalbard in the Barents Sea were examined. On January 8, 2022, signal jamming effects appeared at all three points.

Methodology and preliminary results of experimental researches of the effectiveness of use of GLONASS signals during RTK measurements

The preliminary results of research on the effectiveness of GLONASS when performing RTK measurements. It is shown that a significant effect on the use of GLONASS is observed only at short distances from the base station (30 km). At large distances (121 km),it makes almost no effect or no shows.
