The pulse profiles of the Crab pulsar (as well as some other pulsars) vary with time. They can lead to a major source of intrinsic timing noise, which lacks a detailed physical model. The phase separation Δ between the first left peak (P1) and the s

The problem of the global navigation satellite system carrier-phase ambiguity resolution (AR) has drawn a lot of attention and to some extent been well solved in the past. However, the pulse-phase AR in the pulsar-based navigation has not been fully

Pulsar-based navigation for spacecraft is a revolutionary technology that has been researched for several decades. To validate it, China launched a small experimental satellite, the x-ray pulsar navigation-I (XPNAV-1), whose main payload was the firs
