    On the Performance of Energy Harvesting Dual-Hop Free-Space Optical Communication Systems with Secrecy Analysis by Abdulgani A. Ibrahim, Serdar Özgür Ata, Lütfiye Durak-Ata

    Published 2025-01-01
    “…In this study, we present a dual-hop decode-and-forward relaying-based free-space optical (FSO) communication system. We consider utilizing simultaneous lightwave information and power transfer (SLIPT) with a time-splitting technique at the relay, where the direct current component of the received optical signal is harvested as a transmit power for the relay. …”

    Orbit Determination of China’s Space Station Using Real ISL Measurements of the Tianzhou-6 Spacecraft by Haijian Fang, Fan Wang, Xueming Yu, Baohua Wang, Jiasong Wang, Yufan He, Minzhang Han, Dan Wang, Jingqi Huang

    Published 2024-01-01
    “…In this article, we would like to discuss the idea of jointly using the GNSS observations and ISL ranging and orientation measurements of the Tianzhou-6 (TZ-6) spacecraft to generate the orbit solutions of China’s space station (CSS). Motivated by the requirement of mission implementation, the data processing procedure of the ISL orientation measurements is introduced based on the TZ-6 spacecraft attitude. …”
