Fast time-delay measurement for integrated pulsar pulse profiles

摘要

Purpose - The authors proposed a new method of fast time delay measurement for integrated pulsar pulse profiles in X- ray pulsar-based navigation (XNAV). As a basic observation of exact orientation in XNAV, time of arrival (TOA) can be obtained by time delay measurement of integrated pulsar pulse profiles. Therefore, the main purpose of the paper is to establish a method with fast time delay measurement on the condition of limited spacecraft's computing resources.
