Abstract
GPS is the abbreviation of the English term Global Positioning System global positioning system. The system is the United States laid the second generation satellite radio navigation system. It can provide users with continuous, real-time, global, round-the-clock, high precision three dimensional coordinates, three velocity and time information. Aimed at targets on the ground and in the air around the world an accurate positioning and monitoring. Now, as an advanced GPS receiver navigation and positioning equipment, has a wide range of applications in military and civilian areas.
Thesis mainly research of GPS positioning principle and technology, special magnetic field sensor combination of high-speed microcontroller(MCU) electronic compass and its implementation method.Make a set of design proposal, with soft to link hardware accomplish whole GPS information acceptance and evincive process. Accomplish one handheld GPS position receiving machine with Liquid crystal display, and display real time period and the location of latitude and longitude one by one. By using magnetic resistance(GMR) sensors to collect a certain direction magnetic field intensity, sent to the MCU controller to deal with the data and to assess the results of the corresponding Angle, at last, through the LCD screen display.With the position system complete, the position precision can reach fifteen meters, so the system in measurement an control field application development have some practical worth and reference worth.
Key words:GPS positioning system; Electronic compass;LCD display
