Advanced Communications at Speed and Depth

Since the beginning of Naval Warfare, effective communications with the submarine platform has been a significant challenge. By its very nature, submarine warfare succeeds or fails based upon the stealth abilities of the platform. Covert communications at speed and depth are required to fully engage the platform but providing this capability continues to be challenging. Recent efforts to achieve submarine communications at speed and depth have demonstrated numerous enabling technologies. Through the uses of expendable or tethered communication buoys, RF signals have achieved significant range performance with high reliability. However, such deployments potentially compromise the stealth capabilities of submarine operations under certain situations. Furthermore, tethered communications sensors may not be deployable in certain operational areas. Through the use of spread spectrum signal technology, Progeny Systems will analyze a low probability of intercept (covert) D-ACOMMS solution for A-RCI that can be fielded as both an Advance Process Build (APB) improvement initiative and as a stand-alone transmit / receiver modem solution for use at acoustic ranges or other Navy applications. Capitalizing on digital ACOMMS technologies and solutions already developed for the A-RCI system, our proposal is to analyze and design a Low Frequency (LF) solution for use in long-range communications.
