The invention provides a maritime emergency communication
system which is used for realizing communication in a maritime emergency state and meeting emergency communication requirements in a highly confronting environment in the emergency state. The maritime emergency communication
system comprises a main communication
system and a mobile access communication system. The main communication systemis composed of at least two buoys, carries a
broadband reconfigurable
radio frequency assembly, a communication gateway, an optical
signal processor, an industrial WIFI subsystem, a short-wave communication subsystem, a Beidou navigation subsystem and a
hybrid energy subsystem, and is in
wireless communication with an overhead
airplane and a ship platform. The mobile access communication system iscomposed of a plurality of water surface robots, carries a multi-system full duplex
underwater acoustic communication
machine, an
underwater optical communication machine, a
broadband software reconfigurable
radio frequency module, a short wave communication subsystem, a Beidou navigation subsystem, an
underwater acoustic communication subsystem and an underwater
optical communication subsystem,communicates with an underwater battle platform through an
underwater acoustic communication machine and an underwater
optical communication machine, and communicates with an overhead aircraft and a ship platform in a
wireless communication mode.
