Description	On-orbit demonstration of a space-based VHF Data Exchange System (VDES) for maritime users. The benefits of using VDES in this way are seen as improving safety and communications for ships at sea, with the system a potential long-term replacement for the Automated Identification System (AIS) which ships currently use to broadcast position and status information. NUS’ STAR designed and built the Lumelite-4 microsatellite using the university’s patented modular and scalable satellite’s bus system with fault tolerant features, while ASTAR’s I2R developed the experimental satellite-based communication hardware. This collaboration between NUS and ASTAR signifies the pioneering effort by Singapore researchers to develop a satellite-based high-performance VHF Data Exchange System (VDES), which will significantly improve maritime communications as well as traffic management and analytics. This is also the first demonstration of satellite-based VDES for maritime applications in Southeast Asia.
