Advanced Mission Critical Communication in Maritime Search and Rescue Actions

Successful maritime search and rescue (SAR) missions and real-time information exchange among first responder organizations (FRs) and command/coordination centers, fully rely on straightforward information flow and accurate communication channels, supported by novel data sharing technologies, advanced network connections, and interoperable platforms. Therefore, SAR actions at sea, as an integral part of the national maritime safety system, are supported with mission-critical communication (MCC) networks and devices. The paper presents the analysis of SAR operational and communication specifics, use cases and technical efficiency increasing in the maritime safety framework, with a focus on specific operational capabilities of MCC, connection networks, devices, and procedures for maritime distress communication. Further to MCC, the paper provides insight into the 5G network applied in maritime SAR and communications. The case study consists of an elaboration of the Mission Critical Communication platform components and X/BELLO tool, a secure 5G application that allows real-time information exchange, deployed under the RESPOND-A project approach. These systems represent the technical part of the SAR pilot of the EU RESPOND-A project showcasing the opportunities to strengthen the operational framework of maritime FRs and improve their joint mission performance.
