Abstract

The invention relates to a mixed positioning system of bluetooth beacon and a satellite, which comprises a main controller, a bluetooth beacon positioning module and a satellite positioning module respectively connected with the main controller; the bluetooth beacon positioning module comprises a bluetooth beacon data read device and an arithmetic unit which are sequentially connected; and the main controller controls and manages the bluetooth beacon positioning module and the satellite positioning module. The positioning system uses the bluetooth beacon to support the positioning of a receiving end, can simultaneously make up the defects of the satellite positioning and the mobile base station positioning, and achieve the accurate positioning for covering the inside of building and up to the periphery of the building so as to meet application requirements of different positioning precisions and position service required by a covering area.

Description

technical field [0001] The invention relates to a bluetooth beacon and satellite hybrid positioning system, which belongs to auxiliary positioning products. The invention uses the bluetooth beacon to support the positioning of the receiving end, so as to meet the location service application requirements required by different positioning accuracy and coverage areas. Background technique [0002] The current positioning technology mainly focuses on satellite positioning and mobile base station positioning. Satellite positioning is to convert the received positioning satellite signals into coordinates. This function is usually integrated in satellite positioning chips and related electronic products. Mobile base station positioning converts the mobile phone position by receiving the base station coverage area of ​​the mobile phone signal, and can use the signal arrival time and strength to further improve its positioning accuracy. [0003] However, the above-mentioned satell...
