Abstract
An integrated method and system for communication, positioning, navigation, and timing of a deep-sea vehicle. The method implements integration and deep fusion of communication, positioning, navigation, and timing, and can achieve uniformity of space references and time references between sensors and systems, can reduce difficulty in information fusion, and can implement convenient underwater acoustic communication, real-time/high-update-rate/low-power-consumption/high-precision positioning, high-precision/fault-tolerant navigation, and precise timing. The present invention implements simultaneous operation of four working modes: communication, positioning, navigation, and timing, to fundamentally resolve problems such as insufficient practicability of underwater acoustic communication, low accuracy of navigation and positioning, and no timing function, so as to improve underwater operation efficiency of a deep-sea vehicle.
