摘要(Abstract)：

针对Android移动终端定位精度较差的问题,该文对Android框架结构进行了研究,提出了基于Android移动终端实时BDS/GPS双系统精密单点定位(PPP)方法。利用Android studio 2.2.2、Java语言及JNI技术,对终端GNSS驱动进行开发,成功通过串口读取北斗移动终端RTCM MSM4原始卫星观测数据,并在硬件抽象层进行网络实时差分数据解析、文件读取和输出,最终实现增强定位。在移动终端上运行BDS/GPS实时PPP软件,分析定位结果显示双系统单频精密单点定位精度N、E方向0.6m左右,U方向1.5m左右。

关键词(KeyWords)： Android;实时精密单点定位;驱动;精度分析
