FIELD: data processing.
SUBSTANCE: invention relates to methods for processing digital data using electrical devices for detecting and correcting errors. Method consists in the fact that a functional circuit of the designed on-board electronic device (OED) is developed, then electric circuits of the designed OED are then developed based on it. Developing hardware-software models (HSM) of functional units (FU) of developed OED based on hardware modules that support PXI standard and containing programmable logic integrated circuits (PLIC), which control these modules external input/output channels, simulating the developed OED FU external input/output channels behaviour. On-board systems consisting of OED are recreated on the Earth by means of the developed HSM of FU of OED. Some HSM of FU of the developed OED are replaced with natural FU of the developed OED. A series of experiments is carried out on the Earth in order to detect faults in control objects. Detected faults of the developed OED FU are corrected by their refinement. Control and adjustment iterations are repeated until no faults are detected during the conducted experiments, and the developed OED is then transferred to standard operation by the end user in space.
EFFECT: shorter time for development of OED of LVDS-M of spacecrafts.
