X-ray pulsar-based navigation (XPNAV) is a celestial autonomous navigation method based on X-ray pulsar observation. The pulse phase estimation has been the key point of XPNAV because the balance of accuracy and efficiency in pulse phase estimation is difficult to obtain. In response to this problem, a pulse phase estimation method based on improved particle swarm optimization is proposed. Experiments were conducted based on simulation data and real data. The results demonstrate that the proposed method significantly reduces the CPU time cost of pulse estimation on the premise of guaranteeing high reliability and accuracy.
