The ultimate goal is development of a subsumed navigation layer providing a straightforward mechanism for distributed autonomous guidance algorithms to quickly detect, share, and adapt to changes in the environment using novel distributed navigation controls. Pulsed-RF UWB supports simultaneous communications, peer-to-peer precision ranging, and multi-static radar. Using this single basis technology will enable more and smaller exploratory agents.

Second, this concept can be extended to multiple aerial vehicles flying in tight formation using UWB peer-to-peer ranging.

Multi-robotic search and rescue systems working together to map and sense people in rubble - Cooperative security robots, continually mapping floor plans looking for out of place items - Autonomous chem/bio/rad hazards: small teams of robots with special sensors quickly measure and map the location of hot spots within storage warehouses - Distributed personnel and high-end asset tracking in GPS-denied industrial factories, warehouses, and construction sites - Vehicle collision avoidance safety systems for construction, mining, forestry, and other heavy industries - Formation control in
