On 5 March 2014 at 11:36 local time the on-board computer on Masat-1 switched to it’s redundant pair; the switch was probably caused by a Single Event Latch-Up. The taks of the on-board computer are now performed by the secondary unit, which is completly identical to the primary. The sub-system and Masat-1 are operating without problems since then, so the switch was successful, the redundant system performed exceedingly.
