Proton‐Radiation‐Tolerant Silicon Photonic Charge Sensor for Spacecraft Applications

Advanced Sensor Research, Volume 5, Issue 9, September 2026.
A photonic charge sensor based on silicon photonic crystal waveguides is evaluated under proton irradiation to clarify radiation‐induced optical absorption during operation. The study quantitatively determines absorption increase at 20 keV and demonstrates retained spacecraft‐potential sensing after high‐fluence exposure, providing a quantitative basis

Using Geostationary Satellite Observations to Improve the Monitoring of Vegetation Phenology

Remote Sensing
Geostationary satellite data enable frequent observations of the Earth’s surface, facilitating the rapid monitoring of land covers and changes. However, optical signals over vegetation, represented by the vegetation index (VI), exhibit an anisotropic ...

Communication Satellite Access in the Pacific: Current Status and Implications for Policy

Asia &the Pacific Policy Studies, Volume 13, Issue 3, September 2026.
ABSTRACT This article focuses on communication satellite access in the Pacific Island countries. While satellites can provide telecommunication and internet access, very little academic literature is available about access to satellite communication technology in the Pacific region or policy responses to it.

The Impacts of Southwest Indian Ocean Tropical Cyclones on Transient Weather in Réunion

International Journal of Climatology, Volume 46, Issue 11, September 2026.
Tropical cyclones which make passage near Réunion can have significant impacts on transient weather relative to long‐term means on the island. In this paper, these impacts were determined by a topological analysis of non‐landfalling tropical cyclones. The relationship between storm intensity, distance, duration, and seasonality plays an equal role in ...

Preprocessing Procedure for Propagation Measurements on MEO Satellite Links

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 560-572, September/October 2026.
ABSTRACT This paper presents a software tool designed for preprocessing data from an experimental campaign aimed at characterizing the tropospheric propagation channel using Medium Earth Orbit (MEO) satellites. The collected data provide critical insights into the channel in scenarios involving continuous variations in azimuth and elevation, along with

Tracing Three Decades of Low Earth Orbit Satellite Communication Development: A Bibliometric and Main Path Analysis of Network Architectures, Protocol Evolution, and Emerging Intelligent Services

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 573-593, September/October 2026.
ABSTRACT Low Earth Orbit (LEO) satellite communication systems have evolved into a critical component of global broadband networks, enabling wide‐area connectivity, IoT services, and intelligent multilayer satellite–terrestrial integration. Despite rapid advancements in constellation deployment, routing mechanisms, resource management, and LEO–5G/6G ...

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

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 594-606, September/October 2026.
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 latitudes,

Conditional Diffusion Models for Global Precipitation Map Inpainting

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Incomplete satellite‐based precipitation presents a significant challenge in global monitoring. For example, the Global Satellite Mapping of Precipitation (GSMaP) from the Japan Aerospace Exploration Agency (JAXA) contains regions without valid microwave observations because Low Earth orbiting (LEO) satellites cannot observe the entire globe ...

Precipitation Estimation: From the RAO to EURAINSAT and Beyond [PDF]

, 2004
The key objective of the project "Use of the MSG SEVIRI channels in a combined SSM/I, TRMM and geostationary IR method for rapid updates of rainfall" is the development of algorithms for rapid-update of satellite rainfall estimations at the geostationary
