From mountain search and rescue to natural disaster relief, see how our system can support your SAR efforts

Case studies

Case 1
Mountain search and rescue

Possible scenario:

Avalanche occurred near to popular hiking trail.

Problem:

Search and rescue team requires fast and safe way to check whether there are people in the area that potentially need help.
Application of ASSA SAR:

STEP 1: After arriving in the area the system can be used in random interception mode to detect phones in range from 10 up to 1000m

STEP 2: System registers every phone in its range and displays their list on the Panasonic Toughbook computer

STEP 3: System operator can send a text message to each cell phone in the area stating that search is currently in progress and provide guide on how to contact the search team via the private GSM network created by the system

STEP 4: Operator may then make a voice call to selected number and activate the transmission process in selected phones

STEP 5: Rescue team can then locate the source of the transmission using directional finders

Case 1
Search and rescue in areas with low GSM network coverage
(for example forests or national parks)

Possible scenario:

Search and rescue agency has received a call about a group of people who went missing in a national park, rescue team only knows approximate area where they are likely to be and GSM coverage is very low.

Problem:

The search area suggested by the carrier is very large and contact with the missing group is impossible due to low GSM coverage.
Application of ASSA SAR:

STEP 1: Phone number (MSISDN) or IMSI/IMEI identification numbers of the people who were reported missing are entered into the system

STEP 2: In order to quickly locate them rescue team decides to use a helicopter

STEP 3: ASSA SAR system, when used in target mode, during the flight around the area will only permit registration of phones from the target list

STEP 4: Once any of the phones from the list registers in the system, transmission process in the phone will be activated

STEP 5: Rescue team can then locate the source of transmission using directional finders

Case 1
Search and Rescue after occurrence of a natural disaster

Possible Scenario:

Natural disaster response team arrives in a terrain where hurricane/ earthquake/ flood has occurred in order to locate anyone who is still in the area

Problem:

Many people who are still in the region where the natural disaster has occurred are conscious, however cannot establish contact with the rescue team due to lack of GSM network. Low visibility limits rescue teams ability to assess the amount of people who remained in the area and to locate them.
Application of ASSA SAR:

STEP 1: Durable construction of the system allows it the rescue team to operate it from any vehicle – boat/car/quad/helicopter

STEP 2: System registers every phone in its range and displays their list on the Panasonic Toughbook computer

STEP 3: System operator can send a text message to each cell phone in the area disclosing that search is currently in progress and provide guide on how to contact the search team via the private GSM network created by the system

STEP 4: Rescue team can attempt to call mobile phones in the area via the network created by the system, and gather information on their location

STEP 5: If the communication fails, operator of the system can activate the transmission process in one of the phones and rescue team can trace the source of the transmission using directional finders
