METHOD FOR CONTROLLING THE ORIENTATION OF THE SPACECRAFT Russian patent published in 2021 - IPC B64G1/24 B64G1/44 B64G1/28 

FIELD: space technology.

SUBSTANCE: invention relates to space technology and can be used on spacecraft to provide orientation to the Sun. The spacecraft orientation method provides spacecraft orientation relative to the direction to the Sun using an additional autonomous control loop. The control of the time shadow interval of the orbit is used using a timer triggered by a pulse signal of the terminator or according to information from the onboard ballistic software of the onboard computer. At the first entry into the shadow interval of the orbit, the terminator pulse signal generator can be started not only by information from the on-board ballistic software of the on-board computer, but also by a signal from the solar sensor or by a signal from the ground control complex (GCC). The use of an additional autonomous control loop in normal mode is carried out in the absence of control signals coming into it from the on-board computer during the set control time. After the on-board computer is revived to working capacity by commands from the GCC, it is included in regular operation and an additional autonomous control loop is excluded from the regular control mode of the spacecraft.

EFFECT: increase in the reliability and survivability of the spacecraft.
