The Jet Propulsion Laboratory (JPL) is issuing Request for Information (RFI) No. GO-2672-10292024 to gather insights on developing turn-key products based on the Sensor Open Systems Architecture (SOSA) S3C and High-Performance Spaceflight Computing (HPSC) specifications. This initiative aims to establish a standardized ecosystem of interoperable spacecraft avionics systems, facilitating cost-effective space mission execution and ensuring collaboration among government, industry, and academia.
The request emphasizes the need for technical specifications, including cost estimates and development schedules for an integrated SOSA S3C/HPSC system, which will incorporate elements like single board computers (SBCs), power supply cards (PSCs), and software solutions. NASA seeks feedback from potential developers and users on alternative configurations, market analyses, manufacturing capabilities, and customer support strategies.
This RFI serves as a preliminary exploration to inform potential future Requests for Proposals (RFPs) without committing to procurement. Responses are due by January 31, 2025, enabling NASA to assess industry capabilities and foster partnerships for advancing space-based computing technologies while adhering to industry standards. Calibration of aircraft systems for high-performance computing and fault tolerance is a primary focus to support future space missions.
The SOSA Spacecraft Avionics Standard Content document outlines the specifications and guidelines for developing space avionics systems aligned with the Sensor Open Systems Architecture (SOSA) framework. It focuses on addressing unique space mission challenges, such as radiation, temperature extremes, and vacuum environments, which necessitate high reliability and modularity in avionics systems. Key components include the definition of system requirements, terminology, and specific rules for component configurations (PICs), power supply cards (PSCs), and interface standards to ensure compatibility and interoperability.
The document also presents the structured approach to standardize hardware and promote the use of modular designs, reducing costs and encouraging competition among suppliers. It introduces the SOSA Space Slot Profiles, detailing communication protocols and functionalities required for robust spacecraft operations. By establishing a framework for open standards, the document aims to facilitate technological advancements, allowing for enhanced computing capabilities and reliability in future space applications while adhering to mission constraints. This initiative reflects a shift towards collaborative development of aerospace technologies, leveraging government and industry partnerships to enhance space exploration reliability and capabilities.
