Description: On the example of radio-telescope of RT-70 a question is examined about possibility of the use spline of approximation for the programmatic conduct of drives of space radio-locators and radio-telescopes. Application of spline-approximation yields the results providing necessary accuracy and smoothness of movement of drives of space radars and radiotelescopes. Thus the number of the staff in a file of the initial data should be not less than 40. Certification of a method of spline-approximation is lead.
Keywords: radio-locator, programmatic conduct, a spline is approximation
