【Abstract】 The principle of underwater positioning system is represented, and the theory and method of software implementation of communication interface in the system are introduced. The serial communication model based on the multi-threading is proposed. When the GPS positioning is extended to underwater by the acoustics positioning technology, the coordinate switch formulas and the choice of benchmark are presented.更多还原
