Classification: CPC G | IPC G

Claim 14:
15. A system comprising:
a device;
memory storing data indicating operations for implementing a model for determining a probability that operation of an electronic part of the device will be upset by a single event effect (SEE), flux lookup tables (LUTs), a trajectory of the device, and effective shielding of the device; and
processing circuitry coupled to the memory, the processing circuitry configured to:
partition the trajectory into disjoint time segments;
determine, based on the effective shielding and the flux LUTs for each of the time segments, respective SEE rates experienced by the electronic part for each time segment;
determine, based on the determined respective SEE rates and using the operations of the model, 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.
