Design and Development of Miniature Dual Antenna GPS-GLONASS Receiver for Uninterrupted and Accurate Navigation

Journal of Telecommunications and Information Technology, 2014
Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), and GPS-GLONASS receivers are commonly used for navigation. However, there are some applications where a single antenna interface to a GPS or GPS-GLONASS receiver will not ...

Ionospheric Mechanisms Leading to Plasma‐Bubble Zonal Drift Reversal and Deformation During the 12 November 2025 Geomagnetic Storm

Space Weather, Volume 24, Issue 10, October 2026.
Abstract We present a multi‐instrument analysis of the ionospheric response to the intense geomagnetic storm of 12 November 2025 over the American sector, with emphasis on the longitudinally asymmetric deformation, latitudinal expansion, and zonal drift reversal of equatorial plasma bubbles (EPBs).

Influence of geomagnetic disturbances on scintillations of GLONASS and GPS signals as observed on the Kola Peninsula

Solar-Terrestrial Physics, 2023
We have compared effects of geomagnetic disturbances during magnetic storms of various types (CME and CIR) and during an isolated substorm on scintillations of GLONASS and GPS signals, using a Septentrio PolaRx5 receiver installed in Apatity (Murmansk ...

ScintPi 4.0: A New GNSS‐Based Low‐Cost, Multi‐Constellation, Multi‐Frequency Ionospheric Scintillation and TEC Monitor for Education, Citizen Science, and Research Initiatives

Space Weather, Volume 24, Issue 10, October 2026.
Abstract ScintPi is a series of alternative ionospheric scintillation and total electron content (TEC) monitors. ScintPi monitors have been built by combining single‐board computers (Raspberry Pi) and commercial off‐the‐shelf (COTS) Global Navigation Satellite System (GNSS) receivers.

Physics‐Based Ensemble of Models for F2 Peak Parameters of the Ionosphere: Comparison With COSMIC‐2 Measurements

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Space weather events can significantly alter the ionospheric electron density, affecting signal transmission and navigation accuracy in satellite‐based systems. Consequently, there is an urgent need for reliable forecasting of the Thermosphere‐Ionosphere (TI) system.

Impacts of Mid‐Latitude Ionospheric Dynamics on RF Applications During the November 2025 Superstorm Event

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...
