X射线脉冲星导航是航天器自主导航的一种新方法。该系统利用精确的定时方法获得位置信息。在这些定时模型中，为了获得精确的定时，必须考虑高阶相对论效应对传播信号的影响。时间转移模型在这里提供了详细的两个部分：时间框架转换和相对论效应。
X-ray pulsar navigation (XPNAV) is a new approach for spacecraft autonomous navigation. The system gets position information utilizing accurate timing methods. Among the timing models, the high-order relativistic effects on the propagated signal must be incorporated to attain precise timing. The time transfer model is provided in detail here in two parts: the time frame transformation and the relativistic effects.
