Abstract

The invention relates to a vehicle positioning system based on GPS and GSM short messages. The vehicle positioning system includes a satellite group, a vehicle unit, a monitoring unit and a GSM network. The satellite group sends satellite information to the vehicle unit. The vehicle unit sends satellite signals to the monitoring unit through the GSM network after receives the satellite signals. The vehicle positioning system based on the GPS and GSM short messages can provide continuous and real-time three-dimensional positions, three-dimensional speed and accurate time for users, and has the advantages of high positioning accuracy, multi-function and wide application.

Description

technical field [0001] The invention relates to the field of GPS, in particular to a vehicle positioning system based on GPS and GSM short messages. Background technique [0002] Early positioning systems used radio positioning. Set up many small radio stations all over the city, use the receiver of the car to receive the radio signals sent by each station, and perform positioning with cross positioning. This positioning method has poor accuracy and is expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems, a vehicle positioning system based on GPS and GSM short messages is provided. [0004] The technical solution adopted by the present invention to solve its technical problems is: a vehicle positioning system based on GPS and GSM short messages, including satellite groups, vehicle-mounted units, monitoring units and GSM networks, and the satellite groups send satelli...
