摘　　要：在海域或陆地使用的导航设备若出现故障无法导航,通过卫星电话求援价格昂贵。根据大地主题解算原理,利用安卓手机内置的定位系统,基于JAVA编程语言开发的定位计算软件可在海域没有通信讯号及在陆地手机无信号的情况下,实时获取用户所在地的经纬度和方位,无须购买专用的导航设备。本文详细介绍了软件功能、构成及使用方法。使用本软件可自主、快速地完成导航定位。If the navigation equipment used in sea or land is unable to navigate,it is expensive to seek assistance through satellite telephone.According to the geodetic solution principle,using the built-in Android mobile phone positioning system,based on JAVA programming language,the positioning calculation software developed can acquire the longitude and latitude and location of the user's location in real time without any signal in the sea area and no signal on the land mobile phone,so it doesn't need to purchase special navigation equipment.The function,composition and using method of this software are introduced in detail.Using this software,the navigation and positioning can be completed independently and quickly.
