Classification: CPC G | IPC G

Claim 9:
10. A non-transitory machine-readable medium including instructions that, when executed by a machine, cause the machine to perform operations for determining a probability that operation of an electronic part of a device will be upset by a single event effect (SEE), the operations comprising:
partitioning a trajectory of the device through a region into disjoint time segments;
determining, based on an effective shielding of the device and flux lookup tables (LUTs) for each of the time segments, respective SEE rates experienced by the electronic part for each time segment;
determining, based on the determined respective SEE rates and using a model for determining a value representing a probability that operation of the electronic part of the device will be upset by the SEE, the probability is greater than a specified threshold;
responsive to the determining, adjusting the trajectory or the device until the probability is less than the specified threshold, resulting in a new device or a new trajectory, respectively; and
causing (i) the new device to traverse the trajectory or (ii) the device to traverse the new trajectory.
