针对多于4颗卫星的GPS导航解算及其在嵌入式平台上实现的问题,设计了接收机位置求解算法,在ARM平台上移植嵌入式Linux并实现嵌入式导航软件.首先分析了导航数据提取理论模型,基于最小二乘法设计了接收机位置解算算法.为满足便携性和可移植性,基于ARM9给出了嵌入式GPS导航解算系统平台,并在嵌入Linux系统下设计和开发了GPS导航解算软件.实验结果表明,基于最小二乘法的单点定位精度高,系统可靠性高,可移植性强.%More than four satellites of the GPS navigation solution and its implementation in the embedded platform issues, the receiver position algorithm is designed and an embedded navigation software is achieved to in the ARM embedded Linux platform. The theoretical model of the navigation information extraction is analyzed first,based on least-squares method is used for receiver position solution algorithm. To meet the portability and portability, GPS navigation solution software based on ARM9 embedded Linux system is designed. Experimental results show that single point positioning can get high precision with least-squares method, embedded Linux is reliability, and the software is portability strong.
