基于北斗导航卫星信号的低轨卫星自主定轨（英文） Introduction Theadventofsatellitetechnologyhasrevolutionizedthemannerinwhichhumansnavigatetheirpathontheglobe.Inthisregard,satelliteshaveplayedapivotalroletowardsenhancingthequalityoflifeofindividuals;theyhavetransformedthewaywecommunicate,travel,dobusiness,conductscientificresearch,andprovidevitalservicessuchasweatherandsecurity.Inthepastyears,theGlobalPositioningSystem(GPS)hasbeenthemostwidelyusedsatellitenavigationsystem.However,theChineseBeidouNavigationSatelliteSystem(BDS),aglobalnavigationsatellitesystemofChina,hasrecentlyemergedasanalternativetoGPS.Withthesignificantincreaseinthenumberofsatellitesinorbitglobally,LowEarthOrbitingSatellites(LEOs)haveemergedasanefficientwayofprovidingcommunicationandnavigationservices.ThispaperaimstodiscusstheutilizationofBDS-basedLEOSatelliteAutonomousNavigation.
