Marport's Software Defined Sonar
Marport Deep Sea Technologies has designed and developed Software Defined Sonar (SDS) a broadband, multimode sonar technology platform that uses programmable digital processors to provide the features needed for next-generation underwater sensing, surveillance and communication applications. As a multimode sonar system, SDS is not restricted to operation on a single frequency or proprietary transducers. As such, it can serve a wide variety of legacy sonar applications and can support rapid development and deployment of novel sonar solutions. The flexibility of the system's software configurable "sonar computer" allows users to dynamically tune the transceiver from 1 kHz to 1.8 MHz. The system is designed to increase underwater tactical capability, improve functionality and enhance signal processing and reduces costs; all while replacing racks of legacy sonar equipment. SDS' software-centric architecture can be dynamically reconfigured for multimode sonar functions. Significant amounts of acoustic signal processing are done in software rather than dedicated hardware. The system includes integrated broadband transceiver modules called sonar "blades" that can be scaled to hundreds of channels. The modular package is designed to reduce the size, weight, power and cost of electronics on both legacy and future sonar platforms for submarines, surface vessels and unmanned maritime vehicles. The electronics are designed with commercial-off-the-shelf (COTS) components and utilizes the latest FPGA and DSP technologies. Marport's SDS transceivers and touch screen displays will be used to upgrade the depth sounders
on the Canadian Navy's Halifax class frigates. A patrol boat program is currently underway to develop an 80 channel transceiver and broadband transducer that dynamically operates in the 20 70 kHz spectrum. Codenamed "Caruso SF7" it will be a multimode sonar that integrates depth sounder, doppler current profiler, speed velocity log, parametric sub-bottom profiler and seabed characterization into a single system. A compact version of the SDS transceiver has been selected by a leading manufacturer of side scan sonars for use in a next-generation AUV sonar currently under development. SDS is designed to be an excellent platform for the development of next-generation sensing and communications applications. In addition, it can serve as an alternative for upgrading sonar electronics used for anti-submarine warfare, mine-countermeasures, telemetry and integrated underwater sensing systems.

Termination Tech
Applied Fiber termination technology is opening doors for new advances in engineered tension member solutions using high modulus fiber cable and rope. The technology is designed to make it more practical to substitute synthetic cable for steel and expands the current synthetic boundaries. Whether going deeper with advanced tethers, lifting more with greater precision and safety, reducing connection down-time, creating longer and more efficient seismic streamers, etc; the technology is designed to create new opportunities for synthetic cables to play a more significant role in advancing the subsea industry. While steel has long has a multitude of termination options, synthetics have been limited to the splice or further limited to a small number of bulky fittings with poor and inconsistent breaking efficiencies. Applied Fiber's is seeking to revolutionize the means by which synthetics are terminated. 32 MTR June 2009
