A SMART system is a small pack attached to the dog’s back which consists of a GPS (global positioning system) tracker, a camera, a loudspeaker and a beacon drop system. The SMART system has been developed for mine detection dogs by the Geneva International Centre for Humanitarian Demining (GICHD) and Digger DTR with the initial funding for the sets coming from the Swiss foundation World Without Mines. We are currently running operational trials with Technical Survey Dogs in Cambodia in partnership with the Cambodian Mine Action Center (CMAC), supported by the City of Geneva and the GICHD.
