Accuracy of Indoor Navigation with Bluetooth Beacons

The work is devoted to the problem of constructing information-measuring systems for indoor positioning in the failure or limited availability of satellite navigation data. A model is proposed for estimating the position of an object using Bluetooth sensor data, based on the classic representations of rangefinder beacons systems. When designing a measuring system, this makes it possible to determine the specific errors while estimating the coordinates of an object. This paper presents numerical examples of the accuracy of positioning the object in typical navigation situations. It is shown that the achievable accuracy of determining the coordinates of an object is 1-2m, which is enough for traditional tasks of indoor navigation.
