Integrated LEO Constellation and In‐Cabin Distribution System for Continuous Aircraft 5G Connectivity

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency (>$$ > $$ 500 ms) and inadequate coverage at high ...

Satellite-to-satellite system and orbital error estimates [PDF]

open access: yes
Satellite-to-satellite tracking and orbit computation accuracy is evaluated on the basis of data obtained from near earth spacecraft via the geostationary ATS-6. The near earth spacecraft involved are Apollo-Soyuz, GEOS-3, and NIMBUS-6. In addition ATS-6

Global horizontal irradiance forecast for Finland based on geostationary weather satellite data

open access: yes, 2020
Global horizontal irradiance (GHI) estimates and forecasts are necessary for the efficient use of a naturally fluctuating energy source like solar energy. However, few forecasting methods exist for high latitudes. In this study we present the development

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

Hybrid system of communication and radio determination using two geostationary satellites [PDF]

open access: yes
A new hybrid satellite system which can provide both communications and positioning services in one system using two geostationary satellites is discussed. The distinctive feature is that location information can be provided by transmitting and receiving

Evaluating Satellite Monitoring of Vegetation Health With Fauna Habitat Managers in Mind

open access: yesEcological Management &Restoration, Volume 27, Issue 2, May 2026.
ABSTRACT In Australia, pastoralists, not‐for‐profit, and government organisations are managing stands of open woodland to conserve threatened species' habitats. These land areas are usually larger than a cropping field but smaller than many National Parks in Australia.

Emerging NGSO constellations: spectral coexistence with GSO satellite communication systems

open access: yesFrontiers in Communications and Networks
The rapid expansion of Non-Geostationary Satellite Orbit (NGSO) constellations is reshaping satellite communications, creating complex interference scenarios with Geostationary Satellite Orbit (GSO) systems due to shared spectrum usage.

Snow‐Covered Insights From Above and Below: High‐Frequency Measurement of Nitrogen Dioxide From Space and Ground

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite provides hourly air quality measurements over North America. This study evaluates TEMPO NO2 ${\text{NO}}_{2}$ observations over snow‐covered surfaces, highlighting its ability to capture sharp spatial and temporal gradients in NO2 ${\text{NO}}_{2}$ vertical column densities ...

The Source Brightness Distribution of Terrestrial Gamma‐Ray Flashes From the ALOFT Flight Campaign

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Terrestrial Gamma‐ray Flashes (TGFs) are naturally occurring phenomena that consist of bursts of gamma radiation associated with thunderclouds. Measurements of TGFs have been predominantly based on satellite instruments due to the significantly larger observation area compared to ground measurements. Due to atmospheric attenuation of the gamma
