Maritime rescue terminal based on BDS short message and emergency position indicating radio beacon

Traditional maritime rescue terminals suffer from insufficient positioning accuracy and real-time performance. A maritime rescue terminal is designed for combines the functions of BDS short message and Emergency Position Indicating Radio Beacons (EPIRB). Combined with the command center and related software systems, it can achieve rapid reporting and precise positioning of distress. BeiDou Navigation Satellite System (BDS) short message communication can send messages between terminals and satellites. The COSPAS-SARSAT is an important component of the maritime distress search and rescue system implemented by the International Maritime Satellite Organization. It uses signals sent by EPIRB to locate accident locations and information. Combine the BDS short message with EPIRB, and assemble positioning modules and temperature, heart rate, and other sensors. When the holder is in danger, the terminal will immediately continuously send distress information to the command center, which can provide support for the rescue mission through analysis by the command center. After testing, its dynamic and static positioning accuracy has reached the level of 10 meters; BDS short message, EPIRB working well.
