CDH-FS Image

The CAVU CDH-FS is a state-of-the-art, fully redundant FPGA-based satellite onboard computer system. It’s designed with a backup processor board that seamlessly takes over in case of a primary processor failure, ensuring uninterrupted operation. This redundancy significantly enhances the system’s reliability and safety, a critical feature for space missions.

It utilizes a Microchip/Microsemi SmartFusion2 and ProASIC3 Flash Based FPGAs, which are not only SEU immune but also more power-efficient than conventional SRAM based FPGA architectures.
