System diagram

The command and data handling system of PROITERES satellite is characterized by these features that

• it has 2 main computers,
• the computers run under Linux operating system and
• the computers make TCP/IP based local area network.

They are all for durability as well as higher performance. 2 computers watch each other work properly and each one can reboot the other when it fails. Some of the most important tasks such as attitude control are executed by both computers for redundancy while other tasks are allocated among them for load balancing.

The architecture described above is bold and innovative for a small satellite. We hope our attempts give some availabilities for the successors.
