| The Army has fielded multiple access modems such as iDirect’s Net Modem II and Viasat’s Linkway to make more efficient use of expensive, commercial leased SATCOM capacity to provide a convergence of services utilizing IP over Satellite (IPoS). DoD is working to develop a single standard for such shared access IP modems for use over existing satellites and the soon to be launched Wideband Gapfiller Satellite. DoD Teleport and other DoD Gateways are rolling out the same suite of modems to enable reachback interoperability. These “IP-modems” enable similar capabilities as envisioned for the Transformational Satellite (TSAT) program, including demand assigned multiple access, QoS-based allocation of resources and constellation wide improvements in utilization, through integrated network management. The Army development of unique multiple access waveforms will further enable communications on the move. In order to ensure an integrated approach to the use of Wideband MILSATCOM, the Army has developed a concept of operations for TIPSOTS. This paper provides an architectural view for TIPSOTS, including the various components that makeup the Wideband network. These include tactical terminals, Teleports, STEP sites/Regional hubs, satellites and operations centers. Enhancements are considered that will increase the level of integration between the architecture components to realize a Wideband MILSATCOM segment of the Global Information Grid (GIG). Further information is provided on the use of commercial tools to help DoD create an integrated network operations infrastructure while minimizing new-start development efforts. |
