Abstract
A method includes a device in an area 1 that requests a ultra-wideband (UWB) base station in the areato measure an initial position, and starts inertial measurement unit (IMU) measurement. The device moves to an area, and the device requests to measure distances between each UWB base station in the areaand at least three locations (or obtain, at at least two locations, attitude data of the third electronic device when the device points to each UWB base station in the area). The device A mobile terminal returns to the area, and requests the UWB base station in the areato measure an end point position. The device corrects coordinates of the device in the areacalculated using data obtained through the IMU measurement based on the measured end point position. Calculate the coordinates of each UWB base station in the areabased on the corrected coordinates in the areaand the measured distances between each UWB base station and the device in the area
