基于J2ME平台的GPS导航系统毕业设计论文

摘要

本文系统将在J2ME平台下，利用J2ME的JSR179定位开发包与Google静态地图实现定位、兴趣点添加、路线规划以及离线地图定位等功能。在用户手机硬件支持J2ME和定位功能的情况下，用户只要支付少量的GPRS流量费即可对用户的位置进行定位、路线规划等功能。另外为了节省用户的GPRS流量，设计中也特定开发了离线地图模式，在不联网的情况下，用户依然可以进行GPS定位。

本篇论文将分为七章进行介绍。第一章绪论，介绍课题研究的背景、手机GPS导航发展现状以及课题研究的主要内意和意义；第二章主要对本文系统用的相关技术进行介绍；第三、四、五章为本篇论文的重点，详细阐述了本文系统的需求、详细设计以及存在的问题等；第六章为GPS手机的发展前景展望；第七章则是本篇论文的总结。

Abstract

This paper system will be in J2ME flat, we use the JSR179 positioning and J2ME setups static map realize positioning, Google added interest points, route planning and offline map location etc. Function. In the mobile phone users to locate functional and J2ME hardware support for the case, as long as the users pay a small fee to the GPRS flow can be user location positioning, route planning etc. Function. In order to save the user of GPRS flow, design also developed offline map specific model, not connected to the Internet users can still for the GPS positioning.

This paper will be divided into seven chapter was introduced. The first chapter the introduction, this paper introduces the background of the subject research, mobile GPS navigation development present situation and the main research topic in meaning and significance; The second chapter to the article with the relevant technology of the system are introduced; Chapter 3, 4, 5 in the key for this paper, this paper expounds the system demand, and the detailed design and the existing problem and so on; The sixth chapter for the GPS phone prospect; This paper is the seventh rules summary. 【Key Words】 J2ME，MIDP，GPS，JSR179，Google Static Map
