Abstract: The Littoral Combat Ship (LCS) deploys multiple Unmanned Vehicles in support of the interchangeable Mission Packages. The Multiple Vehicle Communications System (MVCS) provides LCS Mission Packages with the capability to simultaneously communicate with multiple Unmanned Surface Vehicles (USVs) and surfaced Unmanned Underwater Vehicles (UUVs) by providing common data link and network communication services. Aeronix proposes the Spread SC-FDMA Anti Jam MIMO (SSAJM) JTRS SCA compliant waveform for the replacement of the RT-1944 (Sea Lancet) radio within the MVCS system. The SSAJM system has immense potential in both military environments and commercial at sea communications. The waveform will make use of Harris and Aeronix intellectual property to provide a jamming and multipath resistant waveform capable of provide broadband data rates in in a contested environment in heavy sea states (6-9). The waveform will also retain the user interface that are already in place with the current RT-1944 radio, this will enable easy integration into the MVCS and accelerated training of current users. Aeronix will also leverage Harris experience and IP, Harris has a legacy of developing solutions for the most severe communications environments including the unique LCS mission as part of the original RT-1944/U radio.
Benefits: Applications for robust communication systems exist in both the DoD and the commercial markets. Communications in contested environments whether intentional or not are common in military scenarios as well as commercial applications, the interference continues to grow as spectrum use grows. Our solution makes use of SC-FDMA, this is the same physical layer used in the uplink of LTE, any interference resistance mechanism will be directly applicable to commercial LTE systems provided the cost benefit is great enough. The target of this research is for LCS, however the technology and the waveform has many applications across the DoD, potential platforms exist in the following areas: the NAVY fleet in general for close proximity broadband communications, air to sea communications, communications in high multipath environments, and communications in highly contested areas (high interference). Similarly in the commercial world markets for this communication waveform include the following as a small subset, as the application space is large: ship,buoy to shore communications, port communications, oil platform communications, and technology insertion into commercial LTE systems.
