Coordination is vital to emergency operations during natural, accidental, and man-made disasters.  A key component in such coordination is the ability to robustly detect the location of rescue personnel, victims, and building components.  With such information, future command control centers could visualize a disaster site and direct rescues around hazardous areas and towards exits, as needed.

Unfortunately, existing positioning systems are not able to provide the robust location detection needed in these emergency situations.  Beacon systems are not robust because they rely on a single transmitter for an area.  GPS is not a reliable system for indoor location detection.
