主 题:CAPS UWB positioning enhancement pseudolite
摘 要:The positioning precision of the transmitting Chinese Area Positioning System(CAPS) is reduced due to the non-ideal distribution of the satellite *** and navigation enhancement methods are able to improve the reliability and accuracy of the positioning system,especially for users in special regions and special *** this paper,a positioning enhanced scheme based on ultra-wide band(UWB) pseudolite is proposed for *** is demonstrated that the link budget of UWB pseudolite satisfies the FCC s emission mask *** localization algorithm of the enhanced CAPS is *** simulations indicate that the positioning precision of the proposed enhanced scheme is improved greatly,and the feasibility of the enhanced scheme is thus proved.
