A Precision 3-m Radiotelescope for Astronomical Observations at Millimeter and Sub-Millimeter Wavelengths

Abstract

A 3-m Radiotelescope with a surface accuracy of 30¿m (r.m.s.) has been constructed that will be used for astronomical observations at millimeter and sub-millimeter wavelengths. At present the telescope is equipped with a tunable receiver for the frequency range from 80 to 90 GHz, a 256-channel filter spectrometer and an acousto-optic high resolution spectrometer. The various telescope and receiver control functions are carried out by micro-processors, controlled by a POP 11/34 computer.
