 Abstract
With the development of technology, GPS technology has also been applied to various fields quickly, aviation and navigation system, small to personal mobile equipment, all has the figure of it. With the decrease of civilian GPS and cost, has been into people's daily life, many cellphone, PDA and other handheld devices are equipped with GPS functionality. In terms of functionality, GPS is in the Earth's latitude and longitude coordinates of the position of the measured object is measured, and can provide high accuracy and real-time measurement data. For microcontroller-based portable devices, if the holder to acquire location information, the GPS is the best solution.
 Timely control of their own position and the destination of the targeted tracking, monitoring, so as to achieve the defense, for assistance purposes. Meet the motor vehicle's direction, scheduling, managing, monitoring, navigation, communications and other needs. GPS has changed the way people work, improve work efficiency, and has brought enormous social and economic benefits. As people on the transport vehicle monitoring, tracking and improving intelligent management requirements , GPS outbreak in China is about to enter the development stage , tremendous space for development.
This paper shows the principle of main GPS module and technology, programming and microcontroller applications, the LCD screen functionality and its implementation method, the voice system and application functions. Produced a design for the software and hardware combination display and complete the process of broadcasting of the GPS. This subject adopts GPS module VK16U6 ublox, monolithic integrated circuit STC89C52, LCD display screen LCD12864, design a real-time display current location latitude and longitude information , by design, programming , debugging , the positioning system to work properly, to meet the basic requirements of the subject .
