PROVISION OF HIGH SPACECRAFT LIFETIMES BY CONTROLLING SPACE IONIZING RADIATION EXPOSURE UPON AVIONICS
The methods of provision and enhancing spacecraft lifetimes by developing an ionizing radiation exposure monitoring system in order to control remaining spacecraft lifetime, to control structural algorithmic methods of enhancing lifetime and to forecast the impact of ionizing radiation are presented in the paper. The structure of the monitoring system, including space-borne and ground-based segments is suggested, main functions of the systems elements are determined. The accumulative dose (based on MOS-transistors) and heavy ion (based on static RAM) sensors are recommended based on the analysis of potentially applicable principles of space-borne ionizing radiation control in the field of dose and SEE effects. Practical significance of the work is in determination of technical requirements in development of the structure and scope of the space ionizing radiation monitoring system as a whole, its ground-based and space-borne segments, and also in formulation of work development directions.
