Access-controllable indoor positioning method and system

Abstract

The invention relates to the field of radio navigation, and discloses an access-controllable indoor positioning method, which comprises the following steps: N positions Pi in an area which cannot be effectively covered by a known satellite navigation signal being known, performing a scrambling algorithm on position information according to an access control requirement to form a position P'i, anda mapping relationship existing between the Pi and the P'i; transmitting a satellite navigation signal corresponding to the position P'i at each position through satellite navigation signal simulationequipment; and the satellite navigation receiving terminal receiving the navigation signal to obtain positioning information, an authorized user obtaining a real position Pi according to the positioning information and a descrambling algorithm to realize position service, and an unauthorized user has no authorization information, can only obtain disturbed position information, is different from the real position and cannot provide normal service. According to the invention, the problem of positioning of an area which cannot be covered by satellite navigation signals can be effectively solved,and accurate position information acquired by a user can be controlled.

Description

Technical field [0001] The invention relates to the field of radio navigation, in particular to an indoor positioning method and system with controllable access. Background technique [0002] Location services have penetrated into all aspects of people's lives and become an indispensable part of people's lives. However, indoor navigation is still under continuous development and popularization, including WiFi, Bluetooth, UWB, pseudolites, etc. All methods require the construction of a large number of indoor transmission stations to provide users with reference information, and the infrastructure investment is huge, and in general The download cannot restrict users' access to data, and thus cannot establish an effective business model. [0003] In addition, the aforementioned indoor navigation technologies all require users to allocate new user equipment or users to operate the original equipment, and need to change the user's usage habits, which brings difficulties in promotion. ...

Problems solved by technology

However, indoor navigation is still in the process of continuous development and popularization, including WiFi, Bluetooth, UWB, pseudolite, etc. All methods require the construction of a large number of transmitting stations indoors to provide users with reference information, and the infrastructure investment is huge. Under the circumstances, it is impossible to restrict users' access to data, so that it is impossible to establish an effective business model

[0003] In addition, the above-mentioned indoor navigation technologies all require the user to assign new user equipment or the user to operate the original equipment, which requires changing the user's usage habits, which brings difficulties in promotion.
