OBC-1

The CAVU OBC-1 is a highly reliable and efficient FPGA-based satellite computing system that is state-of-the-art. It is designed to ensure smooth and uninterrupted operation during critical space missions. The system has flexible architecture that allows it to be easily scaled up with the same module to make a redundant satellite computer.

This powerful computer system offers a host of features and benefits that make it an ideal choice for space operations. It is designed to withstand a wide range of space environments and ensures that your satellite payload runs smoothly with precise timing, high throughput, and low power consumption. The CAVU OBC-1 makes use of flash-based FPGAs, which are inherently immune to Single Event Upsets (SEUs) and consume less power compared to SRAM-based FPGAs, though with a trade-off in processing speed for certain heavy tasks.
