Description
Non-terrestrial networks (NTNs) can provide ubiquitous coverage and resilient connectivity, but currently only with achievable data rates far from the expectations of 5G networks and 6G forecasts. Terahertz (THz) band technology (0.1-10THz) has recently been envisioned as a potential enabler of high-rate space-based NTNs. This project is aimed at exploring the development of the world’s first community research platform for sub-terahertz satellite communication networks. The platform will consist of two twin small satellites with a software-defined sub-terahertz radio platform that will enable numerous inter-satellite communication experiments, as well as a ground station to investigate the feasibility of ground-to-satellite access links.
This collaborative project brings together interdisciplinary investigators from Northeastern University (NU) and Morehead State University (MSU), including accomplished experts in THz communications, wireless networking, mechanical and aerospace engineering, systems engineering, and satellite development. This two-year effort will focus on developing and testing space-qualified sub-terahertz radios, which will integrate world-record transmit power front-ends at 225 GHz with an ultrabroadband programmable digital signal processing engine. In addition, the satellite bus requirements, including the dimensions and weight of the small satellites, the electrical power system capacity, mechanical interfaces, and deployment procedures, will be analyzed. Moreover, a digital twin simulator will be designed to accurately replicate the entire infrastructure operation and provide extensive inputs to the mission planners.
This project has the potential to revolutionize global connectivity. High-throughput sub-THz NTNs will bridge the Digital Divide by providing reliable high-speed internet to remote and underserved communities. Additionally, the inherent resilience of satellite-based systems offers a reliable communication backbone for critical operations during both natural and human-driven instabilities and catastrophes. Beyond societal impact, the project will contribute to international NTN standardization efforts and spectrum policy development. Furthermore, project findings will be integrated into interdisciplinary courses at both universities, fostering future generations of researchers.
