Loometöö
New method for using commercially available field programmable gate array (FPGA) onboard low earth orbit satellites
In this work, our team succeeded to develop a new methodology to use commercially available FPGA in reliable on-board spacecraft; the method used the Magnetoresistive memory to run memory scrubbing for the chip; this technique mitigated the commonly occurs single event upsets due to radiation effects.
