Problems solved by technology

[0002] At present, during the underwater exploration, detonation, and salvage training of divers or frogmen, for cooperative targets, there are often cases where the target is lost, so that the target cannot be recovered normally. Accurate positioning will greatly affect the smooth progress of actual underwater exploration, detonation, and salvage operations.
