Product Concept

Cost-saving vs Reliability

Our products reduce your total budget for developing a space product. It is often the case that a project uses cheap single board computers because of the limited budget. But the decision may affect whether your mission succeed or not. Or even using radiation hardened parts doesn't solve all of your mission problems nor prevents any crashes of your space product, either. Don't you want to increase reliability with low cost? 

Fault tolerance

In general, almost all of high-reliability products do not have failure tolerant function. Even if a space-graded high-reliability product is used, it's often the case that the computer is failed by single events in space. If the system will be freezed, you can not fix it from the Earth. On the other hand, our product is built on the idea of recovery from failures and has many failure tolerant functions. For instance, it will handle TMR (Triple modular redundancy) and hot/cold standby replication. The failure tolerant functions detect malfunction caused by radiation effects or software bugs in real-time, then it is recovered to normal state.   

Easy of use

Best thing about our product is that all you have to do is to write your mission software and decide your command set, then just forget about everything else. In addition to the failure tolerant function, our products have other useful functions, such as ISS compatible network protocol, TTEthernet and popular middle-ware ROS or cFS. Furthermore, we can custom-design software/CPU board/FPGA as you would like to change.

Space Cubics supports the success of your mission.
