Command and Host Processor Profile

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. The CH profile works alongside the RP Profile and PS Profile to implement 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. The Expansion Profile extends the capability of CH nodes by providing connectivity to non-standard electronics, most often spacecraft bus interfaces.

The processing on CH nodes is performed by software executing on a microprocessor. Connectivity to other resources is accomplished by utilizing the techniques described in the Expansion Profile, and further extends the capabilities of the CH node in supporting many functions as shown below.
