SYSTEM FOR MITIGATING RADIATION EFFECTS ON COMPONENTRY IN SPACE

摘要

A method for mitigating harmful radiation effects on at least one electrical component are disclosed. In a first preferred embodiment, power drawn by the electrical component, such as a GPS receiver, is monitored and compensated by an offset for expected variations due to temperature. When current drawn by the GPS receiver is higher than expected during operation at a given temperature, power to the electrical component is interrupted. Alternatively, or in addition thereto, a second preferred embodiment includes monitoring communications from the GPS receiver. When communications cease or fall below an acceptable level for a predetermined period of time, power to the electrical component is interrupted.
