COMPASS地球参考框架的建立和维持

Establishment and Maintenanceof the Compass Terrestrial Reference Frame

    摘要
  • 摘要: 探讨了COMPAAS地球参考框架所对应的地球参考系统的定义、地球参考框架的建立和维持方案,并选取我国现有的COMPASS跟踪站和IGS跟踪站数据进行了一系列的仿真验证。分析了跟踪站分布对地球参考框架的影响以及多分析中心组合对参考框架周解稳定性和可靠性的影响。试验结果表明,全球均匀分布的跟踪站在20个左右时就能基本满足建立地球参考框架的需求,为了保障地球参考框架的长期稳定性和精度,全球均匀分布的跟踪站应为30个左右;引入多个分析中心组合处理生成最终解不但可以探测出单个数据处理中心所引入的粗差,也可进一步增强周解的稳定性和可靠性。

     

    Abstract: The definition of the COMPASS Terrestrial Reference System,and the establishment and maintenance scheme of COMPASS TRF have been discussed in this paper,and simulated evaluations are carried out using IGS GPS stations and COMPASS stations.The effects of station distributions and the impact of intra-technique combination are investigated in details.The results of the simulation study reveals that about 22 globals distributed stations are needed for the COMPASS TRF establishment,and about 30 globals stations are required its long-term maintenance.It is also confirmed that the stability and reliability of the weekly TRF solution will be improved by the intra-technique combination.
