Abstract
With the launch of a large number of low-orbit satellites at home and abroad,the number of low-orbit giant constellations at home and abroad has gradually increased,and how to tracking,telemetry and command(TT&C)a large number of low-orbit satellites is a major problem encountered at present.This paper comprehensively analyzes the problems and challenges encountered in giant constellations tracking,telemetry and command,and introduces the common tracking,telemetry and command methods of low-orbit giant constellations at home and abroad,including ground-based tracking,telemetry and command,space-ground integrated tracking,telemetry and command,inter-satellite link tracking,telemetry and command,random tracking,telemetry and command,multi-object tracking,telemetry and command,etc.,and systematically sorts out the advantages and disadvantages and research status of various tracking,telemetry and command methods.The new methods of future giant constellation tracking,telemetry and command has been studied,and the integration of V-band tracking,telemetry and command and artificial intelligence and tracking,telemetry and command method is the future development trend.关键词
