RCAF Introduces CASSAR Technology for Enhanced Search and Rescue Operations

The Royal Canadian Air Force (RCAF) has begun implementing a new technology known as the Cellular Airborne Sensors for Search and Rescue (CASSAR) system. This system is being utilized on select aircraft in collaboration with the Civil Air Search and Rescue Association to enhance search and rescue (SAR) operations.

The CASSAR system is currently operational on specific CC-130H Hercules aircraft, which are stationed at 19 Wing Comox in British Columbia, 17 Wing Winnipeg in Manitoba, and 14 Wing Greenwood in Nova Scotia. The technology allows for the identification and communication with individuals who are reported overdue or believed to be in distress, provided their cellphones are turned on and have sufficient battery power.

The system has already been employed in actual search and rescue missions. Notably, on June 8, 2024, it was used to locate a boat with five people onboard that was reported overdue. Similarly, on June 15, 2024, the CASSAR system assisted in locating two missing hunters. In both instances, the technology enabled communication with the individuals involved, despite challenging weather conditions.

Key features of the CASSAR system include:

• It is strictly used for search and rescue purposes, ensuring compliance with the Privacy Act and the Radiocommunication Act. The system does not intercept personal data or retain information beyond immediate mission requirements.
• Coordination with network service providers is in place to prevent interference with cellular networks in the area of operation.
• Emergency distress beacons remain the most direct means of alerting SAR authorities, although the CASSAR system provides an additional layer of capability.

The RCAF states that this technology is expected to improve the speed and effectiveness of search and rescue operations, ultimately saving lives.
