Abstract

The present invention discloses an indoor positioning method and system based on signal multipath propagation measurement, which includes the following steps: step S1, determining an available information source and the coordinates of the available information source among multiple indoor information sources; step S2 1. Obtaining the distance from the mobile terminal to the available information source; step S3, obtaining the current coordinates of the mobile terminal based on the distance; step S4, performing positioning display on the electronic map by the mobile terminal based on the coordinates; step S5 . Perform training of a channel environment fingerprint analysis engine based on the available information source and the coordinates of the mobile terminal. The beneficial effect of the technical solution is that the measurement accuracy of the pseudo-distance between the mobile terminal and the available information source is high, and the public visible base station and publicly visible radio signals, such as LBS, WiFi, WiMAX, FM, ZigBee and other fixed base station signals, are used to achieve positioning , does not require the access authorization of the base station owner, does not increase investment in infrastructure construction and energy consumption, and does not increase the burden of operating costs.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an indoor positioning method and system based on signal multipath propagation measurement. Background technique [0002] Global Navigation Satellite System (GNSS, Global Navigation Satellite System) cannot be applied to indoor positioning and navigation. In order to meet the needs of users for indoor positioning, scholars have developed technologies for indoor positioning based on WiFi, Bluetooth, LBS, ZigBee, and UWB. However, the overall positioning accuracy is not high, and can only reach an accuracy of about 5 meters. The progress that can be achieved by using active RFID technology can reach the centimeter level, but there are many problems in actual use, and the cost of global promotion is very high. The fifth-generation communication technology has a certain positioning capability, but the positioning of 5G relies on its dense base stations, and the positi...
