Abstract :
A set of antenna systems is improved and has the following characteristics. The error of angular pointing is reduced up to 6-7 arc seconds. In control mode for space vehicles it operates at receiving wavelengths of 3.5 cm, 5 cm, 6 cm, 32 cm at noise temperature of an antenna in the range 15-24 K, and on transmission with power of radiation of 200 kW in the continuous mode in ranges 6 cm and 39 cm. In experimental modes of astronomical research and VLBI it provides receiving of signals at wavelengths of 6 cm at effective antenna area of 2100 m2. Some recently perfected RT-70 systems and the experience of their maintenance gives the basis for achievement of the characteristics of RT-70, which allow working at "long" millimeter wavelengths
