摘要

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.
