摘要：随着现代电子工业的发展及通讯行业的突飞猛进，消费电子产品的更新换代，应用领域的逐渐广泛，单片机在这样的大时代背景下获得了广泛的应用和推广。本设计就是在这样的应用背景下选题,然后针对系统的硬件设计、软件设计和软硬件联合调试等方面展开论述。本系统硬件设计分为两部分.:第一部分，接收板是以u-blox公司的GPS模块为核心并结合相关的外围电路实现。第二部分，作为导航数据处理，定位控制以及显示部分的设计，对单片机、液晶屏(12864)以及相关串口设计等也做了相应介绍。本系统的软件设计，采用C51语言编程，完成了单片机初始化程序。

Abstract:With the rapid development of the modern electronics industry, and the communications industry, the upgrading of consumer electronic products, the increasingly widespread field of application, the microcontroller in the context of this era to obtain a wide range of application and promotion.The design is applied in the context of this topic, Secondly, three main parts are expanded in detail, including hardware design, software design and debug of both hardware and software.The hardware design is divided into two parts: First of all, the receiver board is based on GPS module of u-blox and some external circuit. Secondly, as the navigation data processing, positioning, showing,the selection of single-chip and LCD screen (12864) including serial design are also elaborated.The system software is designed with the C51 language.
