Sequential Generation of Multi-GNSS Multi-Frequency PPP-RTK Products and Their Performance Using the EUREF Permanent GNSS Network

open access: yesRemote Sensing, 2023
In the classic Precise Point Positioning (PPP) approach, observations of Global Navigation Satellite Systems (GNSS) are processed at the network level to generate satellite clocks and positions.

Biodiversity under pressure: In search of sustainable planning strategies

open access: yesPeople and Nature, Volume 7, Issue 10, Page 2451-2464, October 2025.
Abstract Land use change in and around urban areas is a major driver of biodiversity loss. Such processes have mostly been studied in large cities, and to a much lesser extent in towns and villages. There is an urgent need for nature positive planning principles that recognize the planetary boundaries and are anchored among decision‐makers.

Evaluating the accuracy of GNSS measurements in RTK mode using commercial and non-commercial correction network

open access: yesТехнічна інженерія
The article presents a comparative analysis of the accuracy of GNSS (Global Navigation Satellite System) measurements in RTK (Real-Time Kinematic) mode using correction services from GeoNet, 1Yocto, EUREF (European Reference Frame) and EGNOS (European ...

Spectral analysis of multi-year GNSS code multipath time-series

open access: yesBudownictwo i Architektura, 2020
In the presented study multi-year time series of changes in the L1 pseudo-range multipath are analysed. Data from 8 stations of the EUREF Permanent Network (EPN) were used in the study.

Characteristics of Large‐Scale Traveling Ionospheric Disturbances During the 10 May 2024 Geomagnetic Storm

open access: yesSpace Weather, Volume 23, Issue 10, October 2025.
Abstract Based on the total electron content (TEC) observation in the Asian‐Australian and American sectors, this paper investigates the characteristics and hemispheric asymmetry of large‐scale traveling ionospheric disturbances (LSTIDs) during the 10 May 2024 superstorm. We found that the amplitudes and meridional phase velocities of LSTIDs in the two

Verification of the Polish Geodetic Reference Frame by Means of a New Solution Based on Permanent GNSS Data from the Years 2011-2014

open access: yesReports on Geodesy and Geoinformatics, 2016
The new solution for the Polish geodetic primary GNSS network was created to verify the currently used reference frame (PL-ETRF2000). The new solution is based on more GNSS data (more daily observation sessions included, a longer data timespan, GLONASS ...

Systematic map of the literature on carbon lock-in induced by long-lived capital

open access: yesEnvironmental Research Letters, 2021
Long-lived capital-stocks (LLCS) such as infrastructure and buildings have significant and long-lasting implications for greenhouse gas emissions. They contribute to carbon lock-in and may hinder a rapid decarbonization of energy systems. Here we provide

Ionospheric Disturbances During the 4 December 2015, Mt. Etna Eruption

open access: yesEarth and Space Science, Volume 12, Issue 10, October 2025.
Abstract This study presents the detection and characterization of co‐volcanic ionospheric disturbances (CVIDs) associated with Mt. Etna's large‐scale lava fountain (Italy). Leveraging a dense and proximal GNSS network, we identify local Total Electron Content (TEC) perturbations extending up to ∼ ${\sim} $200 km south/southwest of the vent.

Exploring Two‐Dimensional and Three‐Dimensional Propagation of Large‐Scale Traveling Ionospheric Disturbances During the May 2024 Geomagnetic Storm Main Phase

open access: yesSpace Weather, Volume 23, Issue 10, October 2025.
Abstract During the main phase of the May 2024 super geomagnetic storm, we investigated large‐scale traveling ionospheric disturbances (LSTID) using data from densely distributed global GNSS receivers. From both two‐dimensional and three‐dimensional (3D) perspectives, we analyzed LSTID propagation characteristics over North America, European, and ...
