Abstract

The invention provides a base station calibration method and device based on a satellite positioning system, and relates to the technical field of positioning. In the base station calibration method,the time service signal provided by the satellite positioning system can be used as the time reference for the positioning base station to send the calibration signal, and the time synchronization ofthe positioning base station is realized by calculating the parameters such as the calibration duration and the delay duration in an outdoor environment or a positioning scene where line arrangement is inconvenient, so that complex wired line arrangement is not needed. Besides, the time service signals provided by the satellite positioning system are wide in coverage range and high in time serviceprecision, so that the calibration efficiency of the plurality of positioning base stations can be remarkably improved, the workload of line arrangement is reduced, and the time synchronization efficiency of the UWB positioning system is improved. The positioning base stations are calibrated based on the time service signals of the satellite positioning system, so that the plurality of positioning base stations can realize accurate time synchronization by adopting a wireless communication mode.

Description

technical field [0001] The present application relates to the technical field of positioning, in particular, to a base station calibration method and device based on a satellite positioning system. Background technique [0002] UWB (Ultra Wideband, ultra-wideband) is a wireless carrier communication technology that uses nanosecond to microsecond non-sine wave narrow pulses to transmit data. In the prior art, the positioning of the terminal can be performed based on the UWB signal. In a UWB positioning system including multiple positioning base stations, each positioning base station in the system needs to work under the same time reference. When performing time synchronization on the positioning base stations, the positioning base stations are usually connected in a wired or wireless manner. In such a system, it is necessary to configure a dedicated synchronization control terminal for the system, and if it is located outdoors or in a large space, it is difficult to arrange...
