GPS / GLONASS Combination Positioning in LBS
GPS/GLONASS 组合定位在LBS 系统中的应用

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 wil...
