The Hepkie system uses ordinary GSM cell phones as beacons, without modifications or any additional programs needed on the phone. The Base Unit triggers signaling from the cell phones in the coverage area so that the direction to them can be detected with the Search Unit(s). The Base Unit is fully automatic and requires no operator, and it presents a list of all cellular phones in the search area to the Search Unit.
Search Unit prototype in action
The operator of the Search Unit can search for all phones present, but can also choose to search for one or several specific phones. The phones belonging to the rescue team or are identified as not belonging to a victim can easily be excluded from the search.
The system is independent of cellular network coverage and it is independent on the service providers. Field trials have showed that the possible range of detection is very large, over 10 km and that it is possible to locate buried cell phones in snow with an accuracy of around 30 cm at a victim depth of 180 cm. There are also very positive results from search in collapsed buildings.
