The Leonardo DRS Blackstone Body-Worn DF / TDOA System provides mission-critical intelligence to the warfighter by rapidly detecting and locating a wide range of threat signals, monitoring signals of interest, and supporting real-time analysis of the signal environment. The system’s light weight, low power consumption, field programmability, and multiple deployment configurations make it well suited for a wide range of operational scenarios. This DF sensor can easily be easily integrated into existing MOLLE/PALS webbing chest rigs and with a tactical radio for internode and squad communications.

The Blackstone System utilizes ruggedized Smartphone Technology for configuration, command and control of the system. It also displays parameters of intercepted signals and the positions of team members overlaid on a geo-referenced map, which  provides situational awareness.
