The offset values of the antenna of the radio telescopes complex "Quasar VLBI"

Transactions of IAA RAS, issue 47, 117–123 (2018)

Keywords: the offset of the radio telescope (RT), the height of the elevation axis RT, the ambient temperature.

Abstract

This article presents the results of measurements of offset antennas of radio telescopes (RT) complex "Quasar VLBI ", as well as the results of the analysis of the dependence of the offset on the influence of the environment. In order to correctly analyze the offset of the displacement value on the influence of the environment, the value of the offset value is considered together with the height of the elevation axis of the radio telescope. In this case, both of these values characterize the spatial position of the elevation axis of the radio telescope. The offset value determines the position of the elevation axis in the horizontal plane, and the height determines the position of the elevation axis in the vertical plane. As a result of the analysis, it was determined that the design of the radio telescope is strongly influenced by the ambient temperature. The dependence of the height of the elevation axis on the temperature is an order of magnitude greater than the analogous parameter associated with the the offset value of the radio telescope. Thus, the calculation of the position of the elevation axis in space is possible with high accuracy.

AB  - This article presents the results of measurements of offset antennas
of radio telescopes (RT) complex "Quasar VLBI ", as well as the
results of the analysis of the dependence of the offset on the
influence of the environment.  In order to correctly analyze the
offset of the displacement value on the influence of the environment,
the value of the offset value is considered together with the height
of the elevation axis of the radio telescope.   In this case, both of
these values characterize the spatial position of the elevation axis
of the radio telescope. The offset value determines the position of
the elevation axis in the horizontal plane, and the height determines
the position of the elevation axis in the vertical plane.  As a
result of the analysis, it was determined that the design of the
radio telescope is strongly influenced by the ambient temperature.
The dependence of the height of the elevation axis on the temperature
is an order of magnitude greater than the analogous parameter
associated with the the offset value of the radio telescope.  Thus,
the calculation of the position of the elevation axis in space is
possible with high accuracy.
