In public protection and disaster relief (PPDR), knowing the exact position of the rescue personnel is crucial.
This work discusses the design of a highly accurate local positioning system (LPS) capable of 3D positioning both in indoor and outdoor scenarios. We discuss the consequences of PPDR scenarios on the system design and the chosen ranging principle. The designed LPS achieves a 3D accuracy below 1m in a variety of scenarios at an update rate of 1 s, while the number of locatable targets is unlimited. The range of the system is 245m. Furthermore, an extension of the application of the LPS towards structural health monitoring is described.
