Increasing the accuracy of measurements in the long-term accumulation mode
at the RATAN-600
The mode of guidance of radio sources using a large reflection radio telescope
can significantly expand the capabilities of the instrument both for studying
the dynamics of variable objects and for implementing time accumulation in problems
requiring high sensitivity. To implement the tracking modes of the RATAN-600
radio telescope, it is necessary to introduce new automation instruments that
provide a new quality of monitoring and controlling the geometry of the antenna
system [1], [2], [3]. To solve these problems in 2020-2022, an automated control
system for the feed movement of type 3 was created and put into operation. The new
automated control system ensures the normal operating modes of the feed, and also,
due to the new possibilities for synchronous control of the movement of the carriage
and the feed cabin, allows developing new methods of observing with the South+Flat
antenna system. The structure of the automated control system is built using standard
(widely available) instruments that support the most common industrial protocols for
data exchange between the intelligent nodes of the complex, which makes it possible
to expand the functions of the complex with low upgrade costs for fitting the
automated control system with additional components of the distributed peripheral.
