Abstract

The invention discloses an exclusive vehicle-mounted GNSS (Global Navigation Satellite System) signal compensation device and an exclusive vehicle-mounted GNSS signal blind compensation positioning system and method. The exclusive vehicle-mounted GNSS signal compensation device solves the position information of a vehicle through a self-built positioning system and simulates a corresponding GNSS simulation signal. The exclusive vehicle-mounted GNSS signal compensation device comprises an encryption module, wherein the encryption module is used for encrypting one or more of time information forrecording the transmission and / or reception of a positioning signal, position information of the vehicle, the GNSS simulation signal and a GNSS satellite signal, and then radiating the encrypted information to a navigation terminal in the vehicle. According to the scheme disclosed by the invention, the information is encrypted, and only the specified application program can realize decryption processing through pre-stored decryption information, so that malicious use of an unauthorized terminal or application program is avoided, and the practical benefits of positioning system manufacturers and cooperative application program merchants are further guaranteed.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an exclusive vehicle-mounted GNSS signal supplementary positioning device, system and method. Background technique [0002] With the rapid development of urban construction, the continuous improvement of people's living standards, and the increasing number of private vehicles, the scene of driving vehicles to unfamiliar roads and areas in the city is becoming more and more common, which has led to people using navigation equipment for vehicle navigation. The frequency is increasing day by day. Existing navigation equipment, whether it is a vehicle navigation equipment or a terminal navigation equipment such as a mobile phone, is based on GNSS (Global Navigation Satellite System) satellite signals to achieve positioning, such as GPS satellite signals in the United States, GLONASS satellite signals in Russia, GALILEO satellite signals in the European Union, and Chinese satelli...
