The Jet Propulsion Laboratory (JPL) in Pasadena, CA, is issuing a Request for Information (RFI) to gather requirements from spacecraft operators and system integrators for Remote Data Concentrators (RDC) used in modern avionics platforms. The goal is to inform the development of a flexible RDC architecture that bridges legacy interfaces (e.g., UART, MIL-STD-1553) with modern high-speed buses like TSN Ethernet, supporting a range of mission-critical and human safety applications. Responses may influence a future procurement decision, including a potential Small Business Set-Aside. The requested information must be provided by July 23, 2026. No specific budget amount is mentioned in the description.
