Professor Yeung recently visited the German Aerospace Center (DLR) in Munich, discussing the shift to digital satellite systems and high-speed optical communications enabled by standards like the ESA Specification for Terabit/sec Optical Links (ESTOL). He introduced BATS technology as a promising solution to enhance multi-hop communications, with Dr. Gianluigi Liva planning a drone-based demonstration to explore its potential. This collaboration underscores our efforts to advance innovative aerospace solutions.
