Description

technical field

[0001] The invention relates to the technical field of ship equipment, in particular to a method, system and unmanned relay equipment for real-time tracking of an underwater robot. Background technique

[0002] With the development of society and the advancement of science and technology, the scope of application of underwater robots is becoming wider and wider, especially in key areas such as marine scientific research and resource exploration. The existing way to monitor the autonomous underwater robot that is working autonomously underwater is to establish an acoustic communication channel between the mother ship and the underwater robot, and implement information exchange such as status and instructions, so as to achieve the purpose of monitoring. The existing method of positioning and tracking the autonomous underwater robot that is performing autonomous operations underwater is: the mother ship and the underwater robot are equipped with acoustic positio...
