Determination of Astrometric Parameters of Millisecond Pulsars via VLBI

  • 摘要: 根据毫秒脉冲星计时测量和深空导航应用的基本原理,分析了对脉冲星位置、自行和视差等天体测量参数的VLBI测量精度需求,讨论了我国VLBI网的现有观测能力和不足及可能的改进途径,包括天线后端配置、时钟同步和数据互相关处理等。

     

    Abstract: The requirement of observation precision of pulsar astrometric parameters including the position, proper motion and parallax by VLBI technique is analyzed based on the fundamental principle of pulse timing observations and the application in deep space navigation of millisecond pulsars. It is also discussed concerning the current technical specifications, the deficiencies as well as the possible ways of improvement in the equipment of electronic backend of antennas, the data cross-correlation processing and the time synchronization of the Chinese VLBI network on the observation of millisecond pulsars for criticism and reference.
