Anti-Jamming Resilient LEO Satellite Swarms

Advancements in wireless communication and electronics in the past decade have propelled the incorporation of non-terrestrial platforms into mainstream communication networks, opening avenues for several new frontier applications. Notably, low earth orbit (LEO) satellite deployments are being proposed for ubiquitous connectivity, both in commercial and military applications, owing to the possibility of rapid prototyping and deployment. This paper introduces an LEO satellite orchestration framework that provides a satellite swarm system with innovative multi-node coordination designs, namely d-MRC and d-LMMSE, to enhance communication capacity while preserving robustness against jamming adversaries. A hardware-in-the-loop testbed has been built with universal software radio peripheral radios and over-the-air transmissions, which closely emulate realworld satellite communications channels. Experimental results with real-time transmissions validate the effectiveness of our designs as compared to single LEO satellite operations.
