ANALYSING INFLUENCE OF THE BOOM THERMAL DISTORTIONS ON THE POINTING ACCURACY OF SPACE LARGE-SIZE ANTENNA
The research analyses the influence of the thermal distortions of reflector booms with a diameter up to 12m on the accuracy of the antennas. It evaluates the effect of temperature differences during operating the spacecraft for its intended purpose in the calculating cases of the summer solstice and the winter solstice. This shows that specified requirements for antenna accuracy are satisfactory for booms. In the course of research the factors affecting the thermal distortions are analised.
