S2CR 7/17 USBL Underwater Acoustic USBL System

S2CR 7/17 USBL is a depth-rated device for long range data transmissions and USBL positioning, providing data transfer rates up to 6.9 kbit/s over a 8000 m range.

Low power consumption makes it ideal for long-term deployment.


  • Long-range operations
  • Transceiver for USBL positioning
  • Reliable communication link
  • Data transmissions and accurate positioning for deep-sea AUVs and ROVs
  • Underwater observatories
  • Underwater acoustic sensor networks

[1] Slant range estimation is based on the measured time delay, slant range accuracy depends on sound velocity profile, refraction and signal-to-noise ratio.

[2] See the S2CR 7/17 USBL Product Information for available standard interface combinations.

[3] User-configurable Listen Mode is only available with a Wake-Up module installed. Power consumption in Listen Mode depends on Listen Mode settings.

[4] Power consumption for the RS-232 interface option. Add 500 mW for the Ethernet interface option.

[5] Contact EvoLogics for more information on power supply options.

[6] Dimensions of a Delrin housing, other builds are slightly larger.
