Scientific paper

The pointing performance of large quasi-paraboloidal radio telescopes may be dominated by temperature differences in the structure. Previous work has concentrated on actively controlling these differences. This paper describes investigations into the pointing of the 32-m MERLIN telescope sited at Cambridge, in particular techniques employed to overcome the influence of thermal effects. It has been found that by measuring temperatures at strategic places on the structure and, using an algorithm derived from the finite element analysis, pointing can be controlled by 6" rms through the sunrise period and in direct sunlight, thus improving the pointing performance by a factor of four.
