Eunomia: A Multicontroller Domain Partitioning Framework in Hierarchical Satellite Network
Qi Zhang, Kun Qiu, Zhe Chen +4
With the rise of mega-satellite constellations, the integration of hierarchical non-terrestrial and terrestrial networks has become a cornerstone of 6G coverage enhancements. In th…
Tyche: A Hybrid Computation Framework of Illumination Pattern for Satellite Beam Hopping
Ziheng Yang, Kun Qiu, Zhe Chen +2
High-Throughput Satellites (HTS) use beam hopping to handle non-uniform and time-varying ground traffic demand. A significant technical challenge in beam hopping is the computation…
Enabling Near-realtime Remote Sensing via Satellite-Ground Collaboration of Large Vision-Language Models
Zihan Li, Jiahao Yang, Yuxin Zhang +2
Large vision-language models (LVLMs) have recently demonstrated great potential in remote sensing (RS) tasks (e.g., disaster monitoring) conducted by low Earth orbit (LEO) satellit…
A Satellite-Ground Synergistic Large Vision-Language Model System for Earth Observation
Yuxin Zhang, Jiahao Yang, Zhe Chen +3
Recently, large vision-language models (LVLMs) unleash powerful analysis capabilities for low Earth orbit (LEO) satellite Earth observation images in the data center. However, fast…
DualAttWaveNet: Multiscale Attention Networks for Satellite Interference Detection
Chunyu Yang, Boyu Yang, Kun Qiu +2
The escalating overlap between non-geostationary orbit (NGSO) and geostationary orbit (GSO) satellite frequency allocations necessitates accurate interference detection methods tha…
