Increasing the reliability of spacecraft is one of the main and still completely unresolved fundamental problems. Redundancy is one of the solutions used in systems, but there are much disadvantages of this method. In the process of many years research, after an attempt to use filter and artificial intelligence and obtaining inconsistent expected results, research was continued and eventually it was revealed that the best solutions for problems are provided by nature, that is, the possibility of solving the problem using biomimetic systems. Fault-tolerance - feature similar to the homeostasis of living objects. To eliminate redundant system, the possibility of integrating self-healing systems were explored. A literature analysis was carried out and the most effective architecture was chosen for solve the redundancy problem - SABRE -architecture, which has sufficient advantages compared to other architectures.
