Forecasting the occurrence of faults in on-board power systems of spacecraft

The authors consider the on-board systems of spacecrafts, and reveal that the most affected system of all of them is on-board energy system. They analyse the shortcomings of the existing system of information analysis of telecontrol signals from the spacecraft, and the algorithm of specialists ’ actions in the elimination occurring failures on-board spacecrafts is analyzed. On the basis of applied catastrophe theory a methodology for predicting malfunctions in the most susceptible to changes in the instrument on the spacecraft side of the energy system is developed.
