Abstract :
Some specific features of every radiotelescope design have an effect on the construction of a regular errors pointing model (corrections) as a function of the radio source coordinates observed. This corrections are related to the azimuth-axis tilt, nonorthogonality of the azimuth and elevation axes and to other reasons. For the purpose of spacecraft tracking in deep space it is very important to set up an accurate corrections model. The present contribution presents some a method of analysis to determine the regular errors of the 64-m radiotelescope pointing.
