| contents | Non-Terrestrial Networks (NTN) are emerging as critical enablers of global connectivity, particularly in remote, unserved, underserved, or maritime regions lacking traditional infrastructure. While much of the existing work on NTN focuses on theoretical or simulated evaluations, practical implementations remain limited. In this paper, we present SpaceNET, a transparent NTN testbed that leverages the Starlink Low Earth Orbit (LEO) satellite constellation in conjunction with Mininet-based emulation to perform end-to-end performance assessments across real-world maritime and terrestrial endpoints that can also be applied to 5th generation (5G). Specifically, we establish a bidirectional link between a ground terminal located in Blacksburg, Virginia, and a maritime terminal aboard a cruise ship near Key West, Florida. We report detailed transmission control protocol (TCP) throughput, user datagram protocol (UDP) throughput, and latency measurements using two different user terminals - a) Smartphone, and b) very small aperture terminal (VSAT), emphasizing the transparent nature of the NTN payload, where the satellite acts solely as a relay node. Our results provide new insights into the performance limits and reliability of commercial LEO-based NTN applications. The SpaceNET testbed offers a reproducible and extensible platform for future research in NTN routing, mobility support, and cross-layer optimization. |
