Artificial intelligence (AI) models developed for Global Navigation Satellite System Reflectometry (GNSS-R) observations have demonstrated competitive performance in estimating geophysical parameters, especially ocean su...

Abstract Active faults release part of the elastic strain energy stored in the crust via aseismic slip, either through slow slip events (SSEs) or steady slowly creep. However, spatial and temporal interactions between th...

La estación permanente UCOR forma parte de la red RAMSAC (Red Argentina de Monitoreo Satelital Continuo) del Instituto Geográfico Nacional (IGN), a nivel transnacional, es integrante de la Red SIRGAS (Sistema de Refere...

This article explores the impact of electromagnetic interference from consumer electronics and common household appliance on the performance of Global Navigation Satellite System (GNSS) receivers in smartphones. As GNSS ...

Measurements from global navigation satellite system reflectometry (GNSS-R) have proven effective for applications in sea surface height (SSH). Deep learning-based methods for spaceborne GNSS-R SSH retrieval can effectiv...

Abstract This paper presents the design of a dual-band and dual-polarized microstrip antenna for global navigation satellite systems reflectometry (GNSS-R) for the L1/E1/B1 and L5/E5a/B2a bands. In order to allow advance...

To fully exploit the advantages of GNSS-R small satellites (large quantity, short revisit cycle) and address key challenges of multisource GNSS-R data—track-wise distribution, uneven spatial coverage, and observat...

Vegetation optical depth (VOD), as a key parameter of vegetation, plays an important role in the process of vegetation growth and change. The spaceborne Global Navigation Satellite System Reflectometry (GNSS-R) technolog...

The use of unmanned aircraft systems to collect data for photogrammetry models has grown significantly in recent years. The accuracy of a photogrammetric model can depend on image georeferencing. The distance from a refe...

The research focuses on the analysis of the accuracy of attitude determination using satellite measurements from a multi-antenna Global Navigation Satellite System (GNSS). Carrier phase satellite measurements are charact...

Abstract This study presents a geodetically derived seismicity-rate model for Kalimantan, Indonesia—a tectonically stable yet geologically diverse region with limited earthquake and fault data. Horizontal GNSS (Global ...

Global Navigation Satellite System Radio Occultation (GNSS-RO) offers a unique means of retrieving vertical atmospheric profiles with high precision and global coverage. This study investigates the spatiotemporal charact...

The present geodetic reference frame in Latin America and the Caribbean is given by a network of about 600 continuously operating GNSS stations. These stations are routinely processed by ten Analysis Centres following th...
