This paper presents a navigation solution tailored for global navigation satellite system (GNSS)-degraded/denied environments, crucial for activities like search and rescue (SAR) operations. The proposed system employs a swarm of unmanned aerial vehicles (UAVs) integrated with reconfigurable intelligent surface (RIS) technology to facilitate position estimation. By redirecting signals from a mobile base station to a ground target via the RIS on the UAVs, the system enables appropiate positioning for SAR tasks. The study investigates various parameters affecting system performance, including swarm formation, ground speed, and flight altitude, providing valuable insights for optimizing navigation solutions in these challenging scenarios.
