Abstract

Abstract

Three quantum ranging positioning schemes against atmospheric interference are proposed based on the analysis of the principle and process of quantum ranging positioning schemes, considering the effects of distance error caused by entangled light passing through the atmospheric ionosphere and troposphere on the accuracy of the system, the relationship among the propagation distance error of the entangled light in the ionosphere, the free electron density in the ionosphere and the frequency of the entangled light, as well as the relationship between the propagation distance error of the entangled light in the troposphere and factors such as pressure, temperature and other factors. Expressions of the three quantum ranging positioning schemes to reduce the ranging error caused by atmospheric interference are derived by performing theoretical analyses.Numerical simulation examples are given to demonstrate that the dual-frequency correction scheme based on three satellites plus one ground station minimizes errors in ranging the atmosphere.
