Hybrid GPS-GSM Localization of Automobile Tracking System

Understand

An integrated GPS-GSM system is proposed to track vehicles using Google Earth application.

• The remote module has a GPS mounted on the moving vehicle to identify its current position, and to be transferred by GSM with other parameters acquired by the automobile's data port as an SMS to a recipient station.
• The received GPS coordinates are filtered using a Kalman filter to enhance the accuracy of measured position.
• After data processing, Google Earth application is used to view the current location and status of each vehicle.
