Advanced Reconfigurable Communications Components
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.
