With the development of communication technology and the improvement of data processing capabilities,location-based services have become one of the most promising internet services.The need to quickly and accurately obtain location information of mobile terminals and provide location services has become increasingly urgent.Due to the closed undergroundenvironment in coal mines,existing satellite positioning systems such as Beidou and GPS cannot be used and onlyindoor positioning technologycan beused.Accurate positioning of underground personnel in coal mines has become an essential system for coal mining enterprises.However,due to the complex underground environment,using UWB alone cannot optimize the path.The integrated positioning withdominantUWB positioning andauxiliary inertial navigation can achieve more accurate positioning.Therefore,this paper studiesthe integrated positioning technology with UWB + inertial navigation.
