Advanced Reconfigurable Communications Components Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-189 Topic Title: Advanced Reconfigurable Communications Components Proposal No.: N102-189-0650 Firm: Trident Systems Inc. 10201 Fairfax Boulevard Suite 300 Fairfax, Virginia 22030-2222 Contact: Jim Faist Phone: (703) 691-7769 Web Site: www.tridsys.com Abstract: Future fielded Naval space communication payloads require a reconfigurable sampling Intermediate Frequency (SIF) filter capability to easily adapt to rapidly changing Navy space communications needs. Our approach for the SIF leverages Trident's extensive embedded programmable DSP processor heritage using FPGAs to meet these requirements and utilizes our proven avionics digital technology and strong space environmental experience to design a SIF that will support a broad range of legacy narrow and future wide bandwidth space communications systems such as the Mobile User Objective System (MUOS) in addition to having extensibility to other payload systems. Our approach includes immunity to destructive single event latch up (SEL), and total ionizing dose tolerance in the 100 krad (Si) and includes SEU mitigation to allow autonomous recovery from SEU induced bit flips. Furthermore, our approach considers the reliability required for the longer-term space geosynchronous missions and entails a full hardware reliability prediction for our system to support single or multiple string spacecraft implementations. The Phase I effort will complete our SIF design with modeling and simulation used to verify unit and system level performance against Navy space applications with the Phase I option proposed to solidify the SIF Phase II unit build and test approach. Benefits: The proposed sampling Intermediate Frequency (SIF) filter offers a number of benefits as a component of the Software Reconfigurable Payloads (SRP) concept for the next generation satellite systems. The reprogrammable nature of the SIF can support a wide range of space communication payloads, thus enabling a much more flexible approach to the design of future Navy space communication platforms than current capabilities. This flexibility will allow for in-space reconfiguration and re-tasking of satellites and ground stations. By utilizing recent advancements in radiation-hardened FPGAs, coupled with the commercially available DSP development tools, the reconfigurable SIF will be have reduced development and testing costs, and reduced on-orbit maintenance costs. This adaptive, reconfigurable implementation also enables the introduction of new capabilities when needed after the system is on-orbit and support sensor applications such as EW and radar. Return
