Abstract

The invention relates to a passive underwater navigation communication positioning system and method. The passive underwater navigation communication positioning system comprises a passive probe unitand a data communication label unit. The passive probe unit comprises a sensitive element, an energy storage element and a power amplifier; the data communication label unit comprises a data processorand a storage element. The sensitive element, the data processor and the power amplifier are connected with one another, and the storage element is connected with the data processor; and the energy storage element is used for providing power for the power amplifier, the data processor and the storage element. The distance between the underwater vehicle and each passive underwater navigation communication positioning system and the position information of each system are combined and thus the actual position of the underwater vehicle can be calculated, so that a problem that the absolute coordinates of the underwater vehicle deviate and cannot be corrected in time after long-time navigation due to accumulated errors, ocean current or crustal movement and other factors can be solved.

Description

technical field [0001] The invention relates to the technical field of underwater communication and navigation, in particular to a passive underwater navigation, communication and positioning system and method. Background technique [0002] At present, the communication, navigation and positioning of underwater systems is a major problem that various countries vigorously develop and solve. Due to the existence of the seawater skin effect, the radio signal enters the water very shallowly, and navigation systems such as GPS are powerless in the water. The energy transmission forms such as sound waves have the characteristics of long-distance underwater transmission, and have become the main means of underwater detection, identification and information transmission. Using underwater acoustic ranging and direction finding as a means, the underwater acoustic positioning system, which determines the coordinates of underwater targets through basic information such as distance / azim...
