Estimation of GNSS tropospheric products and their meteorological exploitation in Slovakia
Contributions to Geophysics and Geodesy, 2020 This paper discusses the in near–real time processing of Global Navigation Satellite System observations at the Department of Theoretical Geodesy at the Slovak University of Technology in Bratislava. Hourly observations from Central Europe are processed with 30 minutes delay to provide tropospheric products.

Investigation on the automatic geo-referencing of archaeological UAV photographs by correlation with pre-existing ortho-photos [PDF]
, 2014 We present a method for the automatic geo-referencing of archaeological photographs captured aboard unmanned aerial vehicles (UAVs), termed UPs. We do so by help of pre-existing ortho-photo maps (OPMs) and digital surface models (DSMs).

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract As global climate change intensifies, hurricane‐induced storm surges are becoming more frequent and severe. While Global Navigation Satellite System‐Interferometric Reflectometry (GNSS‐IR) is widely used to monitor sea level variations, its capability to detect rapid and extreme events remains limited.

GNSS-METEOROLOGY: OPPORTUNITIES AND PROSPECTS FOR DEVELOPMENT IN RUSSIA AND ABROAD
Interexpo GEO-Siberia, 2020 The article considers the possibilities and prospects for the development of GNSS meteorology based on domestic and foreign research. It is noted that the tropospheric delay of the GNSS signal is a valuable source of information about the state of the troposphere.

Automated archiving of archaeological aerial images [PDF]
, 2016 The main purpose of any aerial photo archive is to allow quick access to images based on content and location. Therefore, next to a description of technical parameters and depicted content, georeferencing of every image is of vital importance.

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract The Ross Ice Shelf (RIS) in West Antarctica experienced extensive surface melting in January 2016, driven by warm humid air transported from over the Southern Ocean. Few studies have reported increased atmospheric water vapor and turbulent mixing during this event in this region, where the availability of surface measurements is challenging ...
