Latitude and longitude positioning system design

GPS technology in the military, telecommunications, meteorology, surveying, navigation, remote sensing, geodesy, geodynamics, and astronomy, and many other fields to obtain a very wide range of applications, and promote the rapid development of science and technology, but also enrich the human science and culture life. GPS The exterior design has been gradually to the portable development, and gradually into the lives of people in. Therefore, the study of global positioning system has very important significance.This paper studies the principle of GPS positioning, design a microcontroller-based GPS positioning system, a total is divided into four modules, each module is a single-chip system, GPS positioning module, LCD12864 liquid crystal display module, key circuit module. Which is the use of single-chip system module STC89C52 microcontroller core module as an external peripheral circuits, GPS positioning module UBLOX-6M GPS positioning module. The use of MCU and GPS positioning module for data exchange to obtain the current location information and displays it on LCD12864. Eventually made into a portable GPS positioning device.
