Underwater wireless communication system for purposes of unmanned and autonomous marine platforms

Autonomous Underwater Vehicles (AUVs) move through the water in real time, without operator intervention from the surface. Communication with them takes place periodically or continuously through acoustic signals emitted under water. AUV vehicles used by the Polish Navy are equipped with communication systems of a foreign manufacturer, which in difficult propagation conditions do not ensure reliable transmission. The project provides for the construction of a system demonstrator enabling data transmission in particularly difficult propagation conditions for various applications, operating in two frequency ranges. In the low frequency range from 1 kHz to 50 kHz, the system will enable long-distance communication with AUV vehicles as well as communication between the AUV or a water unit and an object buried in bottom sediments. In the high frequency range from 30 kHz to 150 kHz the system will ensure fast data transmission over a short distance between moving objects.

Performance of low-power underwater modem for shallow water communications
Publication
- Vibrations in Physical Systems - Year 2024
The low-power underwater acoustic modem is usually an important component of the Underwater Wireless Sensor Network (UWSN). Network nodes have predetermined energy resources that will not be replenished during the life of the node. In shallow waters, multipath propagation is constantly occurring and for the modem to work effectively, solutions to overcome them must be used, which will also meet the important criterion of energy...

Suitability of acoustic power amplifiers as power amplifiers in underwater communication systems
Publication
- International Journal of Electronics and Telecommunications - Year 2024
The paper presents selected acoustic power amplifiers from among those currently available. The results of a series of measurements characterising the amplifiers are presented. The measured amplitude and phase characteristics as a function of frequency for four selected amplifiers are analysed. The spectra of the output signal in the band from 4 kHz to 30 kHz are presented. The usefulness of the selected amplifiers in an underwater...
