S2CR USBL Acoustic Modems
S2CR USBL Underwater Acoustic Devices
EvoLogics S2CR USBL is a series of underwater positioning and communication devices for a variety of subsea applications. A single S2CR USBL device, combining a powerful USBL positioning tool with full benefits of an S2C technology communication link, is an efficient choice for application scenarios that demand space-, energy- and cost-saving solutions.
S2CR USBL devices provide USBL tracking and full-duplex digital communication using the EvoLogics patented S2C (Sweep-Spread Carrier) Technology, delivering an excellent all-round performance, resistant to the challenges of a dynamic subsea environment. Self-adaptive algorithms adjust the S2C parameters to maintain the highest bit rate possible in current conditions.
S2CR USBL devices offer accurate and precise USBL tracking of remote targets. Switching between Positioning Mode and Communication Mode is not necessary: positioning data is calculated simultaneously with acoustic transmissions. Both features complement each other in a fully integrated positioning and communication system.
