摘要：GPS简称全球定位系统（Global Positioning System）。简而言之，这是由人造卫星系统，该系统由24颗人造卫星构成。这个系统能保证在任意时刻，我们可以在地球上的任意位置同时观察到4颗卫星，也保证四颗卫星能获取该位置的经纬度和高度，以完成我们所说的定位功能。全球定位系统可以用来引导飞机、船舶、车辆按照用户自己选定的路线来到达目的地，避免了时间消耗和其他的繁琐事务。GPS定位技术主要优点是高准确度，成本小，同时应用面非常广泛，使其在工业领域得到极大的应用。同时，全球定位系统GPS是至今为止高新技术快速发展的代表成就之一，它的可靠性，全面性必然会使他在日后的生活中得到更广泛的应用和深入的研究。94433

因此，本设计的主要内容是单片机的GPS定位装置设计，围绕“基于51单片机实现GPS定位功能”这一课题，利用GPS模块NEO-6M和STC89C52单片机，并且使用 C语言，完成GPS的信息提取，配备液晶显示屏，可以显示时间，经度，纬度，日期等信息，同时配有键盘控制该定位装置。本次设计继承了传统的GPS大多数优点，可靠性高，应用面广，定位准确，具有一定的实用价值。

Abstract: GPS referred to as the Global Positioning System (Global Positioning System)。 In short, this is made up of artificial satellite systems, which consist of 24 artificial satellites。 This system ensures that at any given time, we can observe four satellites at any point on Earth, and also ensure that four satellites can obtain the latitude and longitude and height of the position to accomplish what we call the positioning function。 Global positioning system can be used to guide the aircraft, ships, vehicles in accordance with the user's own route to find the destination, to avoid the time consumption and other cumbersome business。 GPS positioning technology is the main advantage of high accuracy, low cost, while the application of a very wide range, so that it has been a great application in the industrial field。 At the same time, global positioning system GPS is by far the rapid development of high-tech representative of one of its achievements, its reliability, comprehensiveness will make him in the future life of a wider range of applications and in-depth study。

Therefore, the main content of this design is the single-chip GPS positioning device design, focusing on "based on 51 single-chip GPS positioning function," the subject, the use of GPS module NEO-6M and STC89C52 microcontroller, and the use of C language to complete the GPS information extraction, Equipped with liquid crystal display, you can display the time, longitude, latitude, date and other information, while equipped with a keyboard to control the positioning device。 This design inherits most of the advantages of traditional GPS, high reliability, wide application, accurate positioning, with a certain practical value。
