• When Under the current development of mid-to-large size satellites, the high reliability is mandatory to avoid failures and their development cost increases enormously to achieve the high reliability. On the other hand, several universities develop and launch micro-satellites with low cost for the purpose of education from around 2000. To generate new market for satellite utilization, low cost and fast development are key points. The theoretical research toward the balance of cost and reliability is being conducted through the governmental first program "New Space Development and Utilization Paradigm by Micro-satellites Introducing Japan-oriented Reasonable Reliable Systems Engineering". Current reliability is based on the assumption that there is no miss-design and it only depends on the random failure of parts. However, many of real on-orbit failures were caused by design errors. But for the customer to receive service from the satellite system, the number which shows the probability to receive service is more important. In this paper, we propose the method to calculate the new number to show the probability of service and also show the result of the application of this method to the micro-satellite deign to increase the service probability with low development cost.
