The two-temperature standard of noise radio emission consisted of two identical "black" disks with different temperatures is used to increase the accuracy of absolute measurements of cosmic source radio emission flux densities. A brief description is given to the construction of the measuring facility at the RAO NIRFI "Staraya Pustyn'", the measurement procedures and data processing with taking into account apparatus and methodical factors. The results are given of the absolute measurements made in 2003 of the radio emission flux densities of SNRs Cassiopeia A and Taurus A and the radio galaxy Cygnus A at frequencies 2829 and 8834 MHz.
