We have noticed that some of the SRAM devices in use on the satellite are sensitive to Single Event Effects (due to radiation). This typically manifests as increased current.
All our electronics are protected by latch-up circuitry, but some of the increases in currents observed are below the set thresholds of the built-in trip functionality of these circuits.
We have now implemented a further protection mechanism in software which necessitated code uploads to the main on-board computer, some of the power distribution units, as well as the attitude computer.
In parallel we continue to perform minor commissioning activities and regular health checks. We plan to resume commissioning of the attitude control systems this week.
