METHOD OF DETERMINING PERIODICITY OF INSPECTING RANDOM ACCESS MEMORY DURING OPERATION IN RADIATION CONDITIONS OF COSMIC SPACE ON SUN-SYNCHRONOUS ORBIT

摘要

FIELD: information technology. ^ SUBSTANCE: method employs an adaptive strategy of inspecting random-access memory (RAM) taking into account additional conditions for performing operations of inspecting RAM of an on-board digital computer, obtained as a result of a full-scale experiment for testing IC chips of static RAM under cosmic space conditions. ^ EFFECT: high efficiency of a backup on-board digital computer of low-orbiting spacecraft, operating on a sun-synchronous orbit owing to lower time expenses on inspecting and restoring RAM of an on-board digital computer in case of intermittent failure of memory cells in the RAM. ^ 2 dwg
