Transformation of the underwater battlespace will result from continued deployment of network-centric sensors that collect and communicate large amounts of data. This data is converted to a common operational “picture" of the underwater battlespace. The ability to generate the intelligence for successful missions hinges on advanced acoustic communication systems that link together undersea combatants and their associated sensor systems.
Our SeaFire® series of acoustics modems uses reconfigurable embedded processors to enable robust, covert wireless communications among ships, submarines, seabed sensor systems and unmanned underwater vehicles.
SeaFire® modems have been designed to provide efficient wireless data transmission in harsh undersea environments.
The software defined architecture is cognitive and adaptive to the active acoustic channel enabling both low and high data rates to meet demanding undersea communication challenges. Advanced DSP techniques overcome the undesirable effects of multipath and Doppler spread. Vertical configurations or channels with reduced multipath complexity can communicate at high speeds using OFDM modulation. For applications requiring long distance transmission range or noisy acoustic channels a very robust MFSK modulation scheme can be used for improved signal-to-noise ratio. We have a recognised track record in underwater acoustic communication systems and can offer a range of services including system design, development, proof-of-concept trials and technology demonstrations.
