FIELD: aviation.
SUBSTANCE: method of monitoring the present status of the solar battery panel (SB) of the spacecraft (SC) includes the orientation of the SB working surface to the Sun, the measurement of the current values from the SB, the monitoring of the present state of the SB based on the comparison of the present measured current values and current values measured in the previous flight stages. In addition, the orbital orientation of the SC is maintained, in which the axis of rotation of the SB is perpendicular to the plane of the orbit and the normal to the working surface of the SB in the given discrete position is directed to the zenith. Sequentially unfold the SB in discrete positions in which the angle value between the normal to the working surface of the SB and the direction to the Sun is less than a fixed value, the values of the angle between the direction to the Sun and the plane of the spacecraft orbit at the moments of passage of the subsolar point of the orbit passes are measured. Measure the current from the SB at the moment of passage of the subsolar point of the orbit pass, where the measured value of the angle reaches a local minimum, determine the present value of the distance from the Earth to the Sun.
EFFECT: improving the efficiency of monitoring the state of the solar battery of the spacecraft.
