To minimize the risks inherent in the construction of a new mission computer and reduce the "time to market", so the cost of programs, we see appear in recent years has increasingly consistent hardened systems or platforms available on shelves, designated by the acronym COTS (Commercial Off The Shelf). Thus qu'ECRIN Systems developed ONYX, a range of multi-mission computers SWaP-C (Size, Weight and Power and Cost) ruggedized, modular, scalable and qualified MIL-STD-810, DO-160, ready to be used for very different missions across land environment, air, sea. Our GE-IP partner offers in the range CRS calculators VPX 3U and 6U.
