Abstract:

This article introduces the general conditions about Jet Propulsion Laboratory(JPL), and its important status in deep-space exploration activities. The geographical distribution, components and equipments of American Deep Space Network(DSN) are presented; the technical characteristics in signal coverage, telecommand ability, telemetry ability and track measurement of American Deep Space Network are analyzed. The development trends of deep space networks are summarized and prospected. A vision about constructing laser unified Telemetry, Tracking And Command(TT&C) system is conceived, which would be a feasible development direction.
