摘要
Abstract
Five-hundred-meter Aperture Spherical Telescope ( FAST) is the largest and most sensitive ra-dio astronomical telescope in the world. In order to analyze the data transmission support ability of FAST for deep space exploration mission,the data transmission link budget analysis method is adopted. In the provision of specific engineering allowance,the downlink transmission rate of FAST for inner planet,outer planet and Kuiper belt objects exploration mission is calculated. The result shows that,the telescope which is equivalent to a 300-metre aperture receiving antenna will increase the deep space downlink data trans-mission rate by 70~400 times. In the future it will strongly support China's Mars and Jupiter exploration mission.关键词
