The objective of this SBIR is to develop a prototype T-SCAN algorithm to be hosted on WAMS to form and manage multiple simultaneous point-to-multipoint sessions over a transponded satellite for non-networking capable Wideband Anti-jam Modern Systems (WAMS) waveforms. To reduce integration and certification risks, the prototype T-SCAN algorithm is intended to be hosted on the General Purpose Processor (GPP) based subsystem of the WAMS modems and operate at a classification no higher than Unclassified/For Official Use Only (FOUO). In Phase 1, DataSoft will address this challenge by leveraging its experience with the PMW/A 170 Advanced TDMA Interface Processor (ATIP) program, modeling and simulation capabilities, Software Defined Radios (SDR), networking and routing expertise to develop and demonstrate key technologies, for ad-hoc routing, subnet management, multi-channel load balancing, and packet aggregation.
Benefit: The space sector has become a more contested environment than ever, requiring new approaches and closer partnerships to better defend against attacks that are increasingly focused on space assets. It is crucial that the U.S. military improve their readiness and overall resilience in satellite communications. Affordable solutions that enable defense forces to establish connected military communication networks whilst seamlessly operating with other networks will be a focus of MILSATCOM spending and innovation. The WAMS is the Navy's next generation software defined wideband modem for both transponded and processed satellites. Among the waveforms that WAMS will host, there is a waveform that is currently only operable in non-networked point-to-point sessions and this causes inefficiencies. The ability to form networks via T-SCAN will remove the need to set aside dedicated satellite resources to sessions that may not be active at all times; thus, significantly increasing effective satellite resource utilization and mission effectiveness.
