The goal of this paper is to develop a navigation system that uses secondary inertial variables, such as velocity, to enable long-term precise navigation in the absence of Global Positioning System (GPS) and beacon signals. In this scheme, measured zero-velocity duration from the ground reaction sensors is used to reset the accumulated integration errors from accelerometers and gyroscopes in position calculation. With the described system, an average position error of 4 m is achieved at the end of half-hour walks. © 2010 IEEE.EnglishDead reckoninginertial measurementKalman filter (KF)pedestrian navigation systempressure sensor arrayBeacon signalsDead reckoningGround reactionsHigh resolutionInertial measurement unitInertial measurementsIntegration errorPedestrian navigation systemsPersonal navigationPosition errorsPrecise navigationsKalman filtersNavigationNavigation systemsPressure sensorsSensor arraysUnits of measurementGlobal positioning systemArticle10.1109/TIM.2010.2046595
