Mitigating the Scintillation Effect on GNSS Signals Using MP and ROTI

Remote Sensing, 2022
Ionospheric scintillation is one of the main error sources of Global Navigation Satellite System (GNSS) positioning. The presence of scintillation may result in cycle slips, measurement errors or even losses of lock on satellites, eventually leading to ...

The Effects of Dissolved Methane upon Liquid Argon Scintillation Light [PDF]

, 2013
In this paper we report on measurements of the effects of dissolved methane upon argon scintillation light. We monitor the light yield from an alpha source held 20 cm from a cryogenic photomultiplier tube (PMT) assembly as methane is injected into a high-

Features of cyanine dyes aggregation on differently charged TiO2 matrices

Chemical Physics Impact, 2023
Changing the polycondensation reaction route, positively and negatively charged TiO2 nanoparticles have been synthesized. On the base of the synthesized TiO2 nanoparticles, porous TiO2 films have been formed with different surface charges.

Time Series Irradiance Synthesizer for Optical GEO Satellite Downlinks in 5G Networks

Future Internet, 2019
Next generation 5G networks generate a need for broadband, low latency and power efficient backhauling and data-relay services. In this paper, optical satellite communications links, as an integrated component of 5G networks, are studied.

Unseasonal super ionospheric plasma bubble and scintillations seeded by the 2022 Tonga Volcano Eruption related perturbations

Journal of Space Weather and Space Climate, 2022
The Hunga–Tonga volcano eruption at 04:14:45 UT on 15 January 2022 produced various waves propagating globally, disturbing the background atmosphere and ionosphere.

Intra-Day Variability and the Interstellar Medium Towards 0917+624 [PDF]

, 2001
The intra-day variable source 0917+624 displays annual changes in its timescale of variability. This is explained in terms of a scintillation model in which changes in the variability timescale are due to changes in the relative velocity of the ...

A new technique for infrared scintillation measurements [PDF]

, 2016
We propose a new technique to measure the infrared scintillation light yield of rare earth (RE) doped crystals by comparing it to near UV-visible scintillation of a calibrated Pr:(Lu$_{0.75}$Y$_{0.25}$)$_{3}$Al$_5$O$_{12}$ sample. As an example, we apply

Ce3+:Lu3Al5O12–Al2O3 optical nanoceramic scintillators elaborated via a low-temperature glass crystallization route

Journal of Advanced Ceramics, 2023
Transparent Ce:lutetium aluminum garnet (Ce:Lu3Al5O12, Ce:LuAG) ceramics have been regarded as potential scintillator materials due to their relatively high density and atomic number (Zeff).
