Initial Results of RTK/OTF Positioning Using the Ntrip Data Teletransmission Technology

Technical Sciences, 2008
The paper presents the initial results of RTK/OTF satellite measurements made using NTRIP Internet data transmission. Two permanent reference stations belonging to the University of Warmia and Mazury in Olsztyn were used for test measurements. As a result of measurements taken at three measurement points situated 1,5 to 20 kilometers from the reference

Near‐Real‐Time Identification of the Source of Ionospheric Disturbances

Journal of Geophysical Research: Space Physics, Volume 129, Issue 11, November 2024.
Abstract The ionosphere is characterized by a large number of disturbances generated in response to a wide range of phenomena, including natural hazards, space weather and man‐made events. Identification of the origin of ionospheric disturbances (ID), especially in real or near‐real‐time (NRT), is an extremely difficult task, and it is one of the most ...

Ionospheric Nowcasting Over Italy Through Data Assimilation: A Synergy Between IRI UP and IONORING

Space Weather, Volume 22, Issue 5, May 2024.
Abstract An accurate modeling of the ionosphere electron density is pivotal to guarantee the effective operation of communication and navigation systems, particularly during Space Weather events. Despite the crucial contribution of empirical models like the International Reference Ionosphere (IRI), their limitations in predicting ionospheric ...

Three-Point Correlations in Weak Lensing Surveys: Model Predictions and Applications

, 2003
We use the halo model of clustering to compute two- and three-point correlation functions for weak lensing, and apply them in a new statistical technique to measure properties of massive halos. We present analytical results on the eight shear three-point
