About

The CAVU CDH-FS represents the pinnacle of on-board computer systems, featuring a fully redundant FPGA-based architecture designed to guarantee continuous operation. With a backup processor that seamlessly engages upon primary processor failure, this system is not just reliable; it’s essential for critical missions. Engineered to resist severe space conditions like radiation and cosmic rays, it leverages the efficiency and SEU immunity of Microchip/Microsemi SmartFusion2 and ProASIC3 Flash-based FPGAs.
