This article provides a review on X-ray pulsar-based navigation (XNAV). The review starts
with the basic concept of XNAV, and briefly introduces the past, present and future projects …

For SINS/CNS integrated navigation system, the CKF can perform well for state estimation in
Gaussian noise. However, its performances are likely to degrade significantly under non …

A new adaptive interacting multiple model (IMM)-based unbiased finite impulse response
(UFIR)/Kalman filter (KF) algorithm is proposed to provide accurate and robust mini …

Aims. The accuracy of the pulsar period estimation directly affects the restoration effect of the
signal profile. A more accurate pulsar profile will help improve the accuracy of pulsar delay …

Carbon deposition can significantly reduce the working stability and specific impulse
performance of magnesium/carbon dioxide (Mg/CO 2) powder rocket engines; however, few …

High-precision relative position and attitude measurement is crucial for consensus control
and collision avoidance in multi-CubeSat formation flying. However, the traditional relative …

Deep space exploration missions continue to become more ambitious, driving the need to
investigate autonomous navigation systems that are accurate and timely. The solar Doppler …

In X-ray pulsar-based navigation (XPNAV), the appearance of Doppler effects caused by the
dynamic motion of the spacecraft would severely degrade the navigation accuracy. In this …
