Abstract
An operational 960-Mc low-noise receiving system for use in deep-space tracking missions is described. A ruby-cavity maser, low-noise antenna, low-loss transmission line connecting the antenna to the maser and associated instrumentation all combine to yield reliable and low-noise performance. Results of tests on this system in preparation for the Ranger RA-3 lunar probe are presented. The system was successfully used during operations with RA-3. A minimum system temperature of 47°K has been achieved.Keywords
