DOI: 10.1038/s41598-025-25591-3

Abstract: In the surrounding orbits, the position error of the spacecraft causes the distortion of the accumulative pulsar profile. Through theoretical analysis, a non-sensitive direction exists in three-dimensional space. Specifically, the initial position error in the… read more here.
