Today, rapid business and technology innovations are producing an array of advanced commercial satellite communications (COMSATCOM) systems that can deliver massive amounts of SATCOM capacity at a fraction of current cost and offer communications diversity that is critical for achieving resilience in a military contested environment. Recognizing the alignment of commercial capabilities with the Department of Defense (DoD) requirements for high capacity, global coverage, lower cost, and resilience, the department is proactively engaging the industry to formulate strategies leading towards a DoD Wideband SATCOM Enterprise that efficiently acquires and effectively manages advanced commercial capabilities in its architecture. To fully leverage the expanded space resources, the DoD must also address the integration of commercial waveforms into the DoD tactical terminals. The terminal flexibility for operating across multiple operator networks, in multiple frequency bands, and support different waveforms/modems is not only a pre-requisite for accessing advanced services but also key in providing resilience against threats. The purpose of this paper is to provide an architectural overview of the flexible terminal and Flexible Modem Interface (FMI) concepts. The FMI enables managed terminal flexibility and should be considered as an important step in converging DoD tactical terminal segment capabilities for various types of satellite networks and managed services. |
