As a result, the CPPA is considered the main focal point for EEE parts. ESA, Prime contractors and Users have at their disposal one single interface which controls the overall project procurement. This concept enables a wide range of advantages divided into three different temporary stages: pre-procurement, procurement and post-procurement.

Electromagnetic interference (EMI), or electrical noise, is generated by everything from cellphones to solar flares and can make accurate signal transmission as difficult as trying to have a clear conversation in a noisy room. To improve signal clarity in electronic circuits, device designers turn to EMI suppression filters.
