Processors
Published in Monroe Schlessinger, Infrared Technology Fundamentals, 2019
The on-board computational requirements for satellites both under design and proposed have grown well beyond the capabilities of existing space- qualified computers. The problem is extremely critical for the advanced IR satellites, since they require on-board processing systems that are far beyond the capability of all existing hardware. For such satellites to have acceptable life-cycle costs, they must be produced from highly reliable hardware that will operate in space for up to ten years. In space, processor reliability has to be created largely by error-tolerant design concepts in the hardware. The computer must produce accurate data with little or no ground intervention and must survive man-made threats and operate satisfactorily in the space environment.

Human error probability is the probability that the operator makes mistakes when performing a given task. The correct evaluation of HEP can reveal the weak points of the system and the problems of the human-computer interface design, so as to improve the system design or take some preventive measures. Also, the HEP assessment result can be used to decrease the probability of human error and alleviate the harm of human error through changes to the design, training, safety systems, and procedures, resulting in a more operational and error-tolerant design. At present, a lot of research has been done on the evaluation methods of HEP (Ref. 4). These methods are divided into two generations based on the time sequence.
