Abstract： With theacceleration ofsmart city construction and urbanization，large indoor scenes increaseday by day， andthe demand forhigh-precision indoor positioning becomes increasinglyurgent.However，thecomplex indoor environment easilyleads to signalatenuationand sensor noiseinterference.Traditional single-source positioning methodsand traditional fusiontechnologieshavelimitationsinpositioningaccuracyobustess，andreal-timepformance.Asaportableteinal， thesmartphone possesses the hardware advantageof integrating multi-sensors andcommunicationmodules.Therefore，aiming at keyissuessuchasstepcounting，steplengthestimation，andheadingestimationiPedestrianDeadReckoning（PDR），this paper proposes a fusion positioning algorithm based on smartphone PDR andaray antenna.Experimental results show that comparedwithtraditioalemes，tisalgoithignantlymproesoitiongauacycheesherabilitydealtime performance in complex indoor environments，and provides anew directionforthe developmentof high-precision indoor positioning technology.
