(responder mode) through the main port. The Responder trigger can come either from the auxiliary port on a Tritech Micron Sonar, or directly from the MicronNav 200 interface hub. Both the USBL Dunking Transducer and the Micron Modem/Micron Battery Modem can be commanded to switch from positioning mode to data transfer mode, allowing the same hardware to be used to establish an underwater acoustic communications link. -

In addition, conventional systems have poor immunity to the continuously varying background sea noise (such as wave noise). Tritech’s Spread Spectrum technology however does not concentrate the acoustic energy in one waveband but produces a transmission which is linearly varied between 20 kHz and 28 kHz (known as a CHIRP waveform). -
