The Command and Host Processor (CH) profile defines a microprocessor-based solution suitable to construct nodes for mission data processing, spacecraft interfaces, and other applications requiring software execution on microprocessor platforms. Nodes based on the CH profile work alongside other nodes within the JAS architecture. The SMAC Profile and the Communication Profile implement connectivity and data transfer from CH nodes to other nodes in the system.

A CH node may include the following elements:

  • System Monitor and Configuration (SMAC) port
  • Point-of-Load (POL) power converters
  • Host-specific interface electronics
  • Microprocessor
  • Nonvolatile memory for code storage
  • Local memory
  • Radiation Hardened FPGA to provide processor interface logic and time distribution
