Abstract The Joint Architecture Standard (JAS) is a joint project between Los Alamos National Laboratory and Sandia National Laboratories to provide a common processing and communication infrastructure upon which to more quickly develop payload sensing and processing capabilities. JAS offers a flexible, scalable, and reliable solution to space-based processing for our customer's applications. This standardized architecture is a modular design that allows for rapid prototyping and provides faster system integration and testing that reduces development and integration time and costs. The adaptable architecture meets a wide range of performance requirements including: throughput speeds; reliability; Size, Weight and Power (SWaP) reduction; and mechanical and electrical interfaces. The architecture also allows for evolving design changes while minimizing impacts to established interfaces. The primary capability enabling technologies in JAS are packet-switched network connectivity and reconfigurable computing. The fundamental technology of packet-switched networks in JAS are serial interconnects. Because JAS has a broad range of data rate requirements and has the added challenge of providing reliable command, control and data handling in a space environment, this architecture has employed two network tiers connected using Consultative Committee for Space Data Systems (CCSDS) and European Cooperation for Space Standardization (ECSS) communication protocol standards. One of these tiers is driven by high performance gigabit-per-second class communication for high bandwidth sensors and data processing. The other tier is driven by reliable command and control that can also support moderate data transfer rates. SpaceWire is an excellent candidate and is the serial interconnect of choice for the latter tier.
