航天测控系统中的先进GNSS技术:机遇与挑战
Advanced GNSS Technologies for Space Tracking,Telemetry and Command System:Challenges and Opportunities
摘要
Abstract
With the increasing number of spacecraft,relying solely on traditional ground-based Tracking,Telemetry and Command(TT&C)networks to simultaneously track and measure hundreds or thousands of satellites,rockets,and other spacecraft targets will face the problem of scarce TT&C resources,failing to meet the requirements for high-precision navigation.Additionally,the construction and maintenance costs of expanding ground-based TT&C resources are extremely high.The Global Navigation Satellite System(GNSS)provides high-precision Positioning,Navigation,and Timing(PNT)services,making it an indispensable technical means for space TT&C.As a beneficial supplement to ground-based TT&C networks,GNSS can enhance the reliability and precision of spacecraft navigation without significantly increasing mission costs.The application of GNSS in space TT&C systems is explored,the opportunities and challenges it faces are analyzed,and the progress of GNSS applications in spacecraft TT&C in near-Earth space,Earth-Moon space,deep space,and in ground TT&C stations is also reviewed.Furthermore,key challenges and technologies for GNSS support in space TT&C are proposed,including spatio-temporal reference transfer and unification technology,high-sensitivity receivers and high-gain antenna technology,and elastic adaptive fusion processing technology for massive multi-source heterogeneous data.The corresponding insights and recommendations are also provided,offering references for further development and utilization of GNSS in the field of space TT&C.关键词
