Onboard Data Prioritization Using Multi-Class Image Segmentation for Nanosatellites

Remote Sensing
Nanosatellites are proliferating as low-cost, dedicated remote sensing opportunities for small nations. However, nanosatellites’ performance as remote sensing platforms is impaired by low downlink speeds, which typically range from 1200 to 9600 bps ...

IDLB: An SDN‐Based Load‐Balancing Routing Protocol for Autonomous Satellite Constellation Networks

International Journal of Satellite Communications and Networking, Volume 44, Issue 2, Page 109-127, March/April 2026.
ABSTRACT Routing in satellite constellation networks with intersatellite links has become an important aspect to enable broadband Internet access and to integrate into terrestrial networks. However, their dynamic characteristics and large physical size require specifically tailored solutions.

Savings on Transmit Power through Designed Horizon Plane for LEO Satellite Ground Stations

Journal of Communications Software and Systems, 2018
Low Earth Orbit (LEO) satellites are used for public networking and for scientific purposes. Established satellite ground stations can communicate with LEO satellites only when the satellite is in their visibility region, since LEO satellites move too ...

Launch support: Managing complementor bottlenecks in the disruptive innovation of small satellites

Strategic Management Journal, Volume 47, Issue 3, Page 758-803, March 2026.
Abstract Research Summary Through both qualitative and quantitative analyses of large‐rocket providers' support for small‐satellite manufacturers before the emergence of small rockets, we examine how disruptors to an incumbent ecosystem gain support from complementors of the incumbent technology.

Fourier Neural Operator for Moonquake Detection

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Moonquakes provide critical observations for probing the lunar interior, yet their analysis is hindered by the limited number of recordings and their inherently low signal‐to‐noise ratio (S/N). Conventional detection methods such as Short‐Term Average/Long‐Term Average (STA/LTA) perform poorly on lunar data, while standard deep learning models

MMS Observations of Whistler‐Mode Waves: Comparison Between the Observed and Theoretically Predicted Electric Field

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Electric field instruments function by electrically coupling to the surrounding plasma, resulting in a response function that varies depending on local conditions. This variable coupling can complicate quantitative interpretation of wave measurements, yet is rarely considered.

Harnessing Satellite Constellations as Signals of Opportunity for an Enhanced Specification of the Satellite Drag Environment in the Critical LEO Regime

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Enhancing the accuracy of orbit predictions for low‐Earth orbit (LEO) satellites and debris is vitally important for satellite owner/operators dedicated to ensuring the safety and sustainability of the LEO environment. Presently, the largest source of error in orbit predictions stems from uncertainties in the estimation of thermospheric mass ...
