中文摘要: 研究了GPS 和GLONASS 之间坐标系统和时间系统的转换关系，结合单系统伪距定位观测方程，推导出组合定位下的伪距观测方程及其求解方法，并编程实现。实验分析表明，GPS/GLONASS 组合定位在观测条件不好的情况下，定位精度明显优于单定位系统。应用于LBS 系统，将提高LBS 的服务质量，推动LBS 的发展。
Abstract:This paper studies the coordinate systems and the time conversion relationship between GPS and GLONASS, combined with the observation equation of a single Pseudo-range positioning system. It deduces Pseudo-range observation equation under integrated positioning and its solution, then programming it. Experimental analysis shows that positioning accuracy of GPS / GLONASS integrated system is much better than a single positioning system in the case of poor observing conditions. Applied to LBS System, this system will improve the quality of LBS and promote the development of LBS.
