Aitech Defense Systems Inc. in Chatsworth, Calif., is offering a radiation-tolerant, single-slot 3U Compact PCI single-board computer, based on the PowerPC 750FX microprocessor, for manned and robotic space vehicles that must operate in radiation environments. The conduction-cooled embedded computer, called the S950, is for redundant mission computers, flight guidance and navigation computers, and command- and data-handling computers. The board also has a silicon-on-insulator processor for reduced power consumption, increased processor speed, and radiation tolerance.
