FIELD: aviation.
SUBSTANCE: measurement of present angular position of solar battery (SB) and determination of the given Sun orientation. In the event of difference between the given direction and SB current angular position the SB rotation instructions are formed and rotational speed of output shaft of SB rotation device is set up. This speed is a sequence higher than rotational speed of spacecraft around the Earth. Before the control has started time and SB deceleration angle is determined from the instruction issue to the full stop. Angle threshold value is determined as angle of less than 180º and exceeding the sum of deceleration angle and angular value of the same discrete sector of SB angle transmitter. The time control threshold value is set as the ratio of angle control threshold value to the SB rotational speed. After rotation cessation instruction has been formed, the current SB position is stored and running control time is measured. The current control time measurement is ceased and its value is set to zero if SB clockwise or anticlockwise instruction has been issued before the current control time gains threshold value. At the moment of gaining the threshold value by current control time the current angular SB position is measured and compared with its stored value. If the current angular SB position differs from the restored one by value exceeding the control angle threshold value, SB control is stopped and a failure signal is initiated.
EFFECT: enhancement of method of controlling by imposing controls without SB reorientation after preset angle attaining.
