Rapid growth in space missions necessitates the onboard intelligence, which creates autonomous space systems by providing high level decision making, robust execution of decisions, and automatic fault repairing. Mostly, autonomous space systems are implemented as hybrid architectures with a few conceptual layers. Validating the stability and evaluating the performance of an autonomous architecture...
Plug and play satellite (PnPSat) is an Air Force Research Laboratory (AFRL) technology demonstration spacecraft developed to provide flight validation of the viability of AFRL's PnP architecture and technologies. Microcosm and its partner HRP Systems have led the development of the PnP attitude determination and control system (ADCS) as part of the definition and implementation of the flight software...
Owners and operators of air and space vehicles frequently desire to retrofit health management technology onto their platforms. Prognostics and condition based maintenance processes offer the promise of higher availability, reduced operating costs, and improved maintenance efficiency. An effective health management system, judiciously applied, can positively impact these goals, but to be effective...
The purpose of TAFT fault tolerance studies conducted at CNES is to prepare the space community for the significant evolution linked to the usage of COTS components for developing spacecraft supercomputers. CNES has patented the DMT and DT2 fault-tolerant architectures with 'light' features. The development of a DMT/DT2 testbench based on a PowerPC7448 microprocessor from e2v is presented in this...
