Keywords: onboard control complex, majority reservation, reconfigurable computing field

In this article we examine the procedure of low level reservation of the basic hardware architecture of the earlier offered reconfigurable complex functional monitoring and diagnostics system of the onboard spacecraft control. We offer to use this procedure as a part of a uniform reconfigurable computing field for reliability improvement of the monitoring and diagnostics system without resorting to use of external additional hardware. In case ofusing the majority reservation procedures, it is also offered to realize majority organs by means of hardware method on the basis of selected fragments of the reconfigurable computing field. Consequently, we deal with two options of localization of the basic hardware architecture of the functional areas and the majority organs corresponding to them, as a part of a uniform reconfigurable computing field in monitoring and diagnostics system. As a result, we obtain an expression for calculating the probability of trouble-free operation of the hardware architecture of functional areas realized according to the triple majority reservation diagram.
