Details:
The SIS-1625 Seafloor Imaging System has quickly become the industry standard for shallow water (<2000M) seafloor survey operations. This field proven, highly versatile survey tool offers a fully digital platform capable of collecting high resolution chirp side scan/sub-bottom data, as well as a full suite of customer selected sensor data. The high resolution, extended range chirp data and multiple data sensor capability provide the surveyor with a significant savings in instrument cost and survey time.
The TTV-290 is a fully digital platform with standard Chirp side scan/sub-bottom transducer arrays, digital multiplexor, subsea electronics, and RS-232 ports for optional sensors. The hydrodynamically stable tow vehicle includes pitch, roll and heading sensors, optional position responder/ transponder, and other customer selected sensors. The TTV-290 has a 0.5 degrees side scan sonar horizontal radiation pattern, combined with broad band Chirp DSP match filter processing, provides optimal cross-track and along track resolution.
Chirp DSP based side scan sonar, operates at 100/400 kHz simultaneously, and allows a full 1000 meter swath, with resolution equivalent to much higher frequency systems. The Chirp DSP/CW based sub-bottom profiling, operates at 1 to 10 kHz region, and allows maximum sediment penetration with greatly improved resolution.
The communications link was designed through a program to develop a full ocean depth telemetry module for a multi-sensor seafloor mapping system. The two-way communication with the tow vehicle is over a single coax with digital high speed multiplexor, with standard cable lengths up to 10,000 meters. The communication rate for sonar data is up to 5 megabit/sec and for the uplink and downlink status is 9600 bits/sec.
