In this paper the hardware-software complex is presented. It has been developed to teach developers of technical systems to effective fault-tolerant approach, applied to a gyroscopic sensors unit (GSU). The fault-tolerant method used on the complex has the ability to perform a complete diagnosis of the GSU, constantly monitoring its state by means of several comparisons, determining the possible existence of a fault in the unit. Once a fault in the unit has occurred, the method is able to find where the fault is located; allowing us to define what kind of fault has appeared in the unit and this diagnosis can lead us to perform the proper corrective actions to recover the optimal performance of the GSU. Keywords: fault-tolerant system, control system, fault-tolerant, gyroscopic sensors unit.
