Embodiment

[0041] Such as figure 1 As shown, a security location method applicable to IPV6 network comprises the following steps:

[0042] Use the base station signal transceiver, the WIFI signal transceiver and the GPS signal transceiver to receive the base station signal, the WIFI signal and the GPS signal 101 .

[0043] Send the collected base station signal, WIFI signal and GPS signal to the remote server 102 .

[0044] The remote server analyzes the base station signal, the WIFI signal and the GPS signal respectively and performs cross-comparison 103 .

[0045] If there is a significant difference in the positions provided by the three signals in 103 , it indicates that the GPS signal may be spoofed 104 .

[0046] According to the analysis results of 103 and 104, the GPS positioning information is confirmed or a GPS signal fraud alarm 105 is issued.

[0047] The method of base station assisted positioning to verify GPS positioning is as follows: figure 2 shown, including:

Abstract

The invention discloses a safety positioning method suitable for an IPV6 network. Mobile equipment and a far-end server are included; the base station signal receiver sends a connection request to theplurality of adjacent communication base stations, obtains base station information and sends the base station information to the far-end server, and the far-end server calculates first position information of the mobile equipment according to the base station information and coordinates; WIFI access point information is acquired the WIFI access point information is sent to a remote server, and the remote server calculates and obtains second position information of the mobile device according to the WIFI access point information; the remote server carries out cross comparison on the first position information, the second position information and the acquired GPS signal and judges whether positioning deviation exists or not; and if the positioning deviation is greater than a certain threshold, it is judged that GPS interference exists, otherwise, it is judged that the GPS positioning is accurate. The GPS positioning accuracy can be verified, GPS interference can be discovered and eliminated, and auxiliary positioning can be provided under the condition of interference.

Description

technical field [0001] The invention relates to the technical field of GPS positioning security, in particular to a secure positioning method and system applicable to an IPV6 network. Background technique [0002] GPS is currently the most important positioning system, widely used in mobile devices such as mobile phones, vehicles and drones. However, due to the existence of GPS fraudulent interference devices, the reliability of positioning is challenged, resulting in immeasurable economic losses. GPS obtains GPS satellite signals through the GPS signal receiver on the mobile device, thereby calculating the position of the device. The GPS fraudulent device interferes with the positioning of mobile devices by forging GPS broadcast signals, causing device users to misjudge their own location and deviate from the correct route. [0003] Patent document CN 104914455 discloses a method for solving inaccurate GPS positioning of mobile devices, which uses WIFI and trusted positio...
