Adaptive Computer System

In Phase 1, a scaleable Plug and Play interface will be developed and demonstratedin a multibus architecture with 4-8 modules. These modules can be added andremoved at will without any reprogramming. Any failure or latch of anymodule will not stop bus communication with the remaining modules. A demonstrationwill be conducted simulating the addition, removal, and failure of various nodesIn Phase 2, a Plug and Play interface will be developed capable of supporting anadaptive network architecture that can be implemented into a future AirProgram spacecraft. This effort will include the fabrication of a simulatedshaped micro-spacecraft with eight Plug and Play panels to demonstrate thecapability of this interface. The micro-spacecraft structure will include adaptivecabling capable of reconfiguring itself to allow different subsystems to be addedto the spacecraft. OEI has already developed the structure, panels and cablinginterfaces for this cube shaped micro-spacecraft through previous research anddevelopment efforts.In Phase 3, this system will be promoted as a means to lower barriers of entry toproviders of spacecraft components and subsystems by providing a common interfacethat eliminates the problem of proprietary bus architectures.The benefits of a Plug and Play interface will enable faster spacecraftintegration thus reducing time and cost. Heritage subsystems can be equippedwith front end Plug and Play modules to interface with any spacecraft reducingdevelopment costs. Dynamic reconfiguration will enable on-orbit assets to beupdated by the addition of Plug and Play orbital replacement units.
