“…In calculating the probability of doze failures in IMC of various types, included in the onboard instrumentation of the Fobos-Grunt spacecraft, the technique was used, which is described in detail in [2,3]. All considered IMCs were subdivided in 10 groups according Abstract -When designing the radio-electronic equipment for long-term operation in a space environment, one of the most important problems is a correct estimation of radiation stability of its electric and radio components (ERC) against radiation-stimulated doze failures and one-particle effects (upsets).…”
