Abstract
In order to carry out an RF link analysis for a Search and Rescue Satellite System (SARSAT) it is necessary to determine the apparent noise temperature of the earth, as seen by the spacecraft antennas. Such an analysis has been carried out in the United States. The report summarizes work carried out by the Communications Research Centre (CRC) in order, first, to verify the original noise temperature estimates, and second, to extend this work to cover Canadian remote area situation in which urban areas of the U.S.A. do not contribute significantly to the observed noise levels.
