Aitech Explores COTS in Space

January 13, 2018

With the recent shift in space electronics using ruggedized commercial components as a cost-efficient alternative to ‘space-grade’ devices, the question of reliability has been asked repeatedly. And rightly so, as there are a number of variables to consider when factoring in the effects of space on non-qualified components.

Space is not only one of the harshest environments that electronics need to operate in, but it’s also one of the hardest to replicate. Testing and validation of mission critical systems used in space exist for a reason, as success is defined by the continued reliability, autonomous operation and unwavering communication of a space system within its network. So, while the answer isn’t simply yes or no, there are certain instances where a more definitive answer can be found. Depending on the program’s mission requirements, some limits may be OK to push, while others may yield catastrophic failures.

This paper looks at reliability requirements today, but as limitations become more clearly defined within specific applications, the logical course of events would lead to a continued increase of COTS components in space.
