Abstract | X射线脉冲星自主导航(XNAV)中,时间测量与转换误差会对导航精度产生不可忽视的影响. 本文在对XNAV算法研究的基础上,进一步研究了利用差分抑制时间测量与转换误差对导航精度的影响. 研究结果表明:双差能有效抑制时间测量误差对导航精度的影响,但是无法抑制时间转换误差对导航精度的影响;三差既能有效抑制时间测量误差对导航精度的影响,也能有效抑制时间转换误差对导航精度的影响. |
Other Abstract | Because the essence of the traditional X-ray pulsar navigation (XNAV) is to measure and convert the time accurately, the errors of time measurement and conversion can affect the navigation precision. In the paper, measurement difference is adopted to reduce the effect of time measurement and conversion errors to navigation precision. Results demonstrate that double differences can reduce the effect of time measurement error to navigation precision, but can not reduce the effect of time conversion error to navigation precision, meanwhile, triple differences can reduce both the effect of time measurement and conversion errors to navigation precision. The research results are referable to the application of XNAV. |
