摘要
梳理了国内外空间站天基测控通信应用的概况,针对近地载人航天对测控通信系统的高要求,分析提出中继卫星系统的发展建议,以及导航卫星和低轨卫星星座系统的特点优势。调整中继卫星轨位、增加中继激光链路、采用全景波束全时监控模式,以及导航卫星和低轨卫星星座作为必要补充等途径,可为载人航天测控通信提供更好的灵活性、可用性和效费比。为载人航天天基测控通信发展提供了参考依据。
The space-based TT&C and communication application for manned space flight are summed up,both at home and abroad.The development of tracking and data relay satellite system is proposed,and the advantages of navigational satellite and LEO satellite constellation systems are discussed,in response to the high requirements of TT&C for China’s manned space flight.Orbital positions adjustment and deploying laser link on tracking and data relay satellite system,and using S-band multiple access(SMA)panoramic beam to monitor manned spacecraft at anytime and anyplace are needed.Navigational satellite and LEO satellite constellation systems are necessary supplements.These space-based TT&C and communication approaches are more flexible,usable and higher cost-effectiveness for manned space flight.The conclusion can provide reference bases for subsequent development of the space-based TT&C and communication for manned space flight.
