Abstract Extreme conditions during storms profoundly alter the evolution of equatorial plasma bubbles (EPBs), yet the key dynamics remains poorly understood. We document the rapid expansion, contraction, and decay of super EPBs in South America during the 12 November 2025 storm with Interplanetary Magnetic Field (IMF) Bz/By magnitude exceeding ∼50 nT ...

Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...

Global Long‐Term Trends in Ionospheric TEC From GNSS Observations With Local‐Time Dependence
Abstract Long‐term ionospheric changes are expected as a consequence of thermospheric cooling driven by increasing greenhouse gas concentrations. We analyze global ionospheric total electron content (TEC) derived from GNSS observations for 2000–2024 using the high‐resolution ISEE data set.

CROCOORD – android aplikacija za multi-GNSS izmjeru
Tehnološki napredak hardvera mobilnih telefona i sučelja za programiranje Android aplikacija (API) omogućuje određivanje položaja pomoću mobilnih telefona s povećanom točnošću koja do sada nije bila moguća. Pojavom mogućnosti pristupu neobrađenim GNSS mjerenjima i dvofrekvencijskih GNSS čipova u mobilnim telefonima otvorena je mogućnost korištenja ...
