摘　　要：针对两大定位系统(GPS或GLONASS)单一定位存在众多不足:定位数据不准确,可靠性不高,易受环境影响等,而GPS/GLONASS一体化定位则在可靠性、定位精度、操作效率、信息安全等方面都得到明显改善;为此,提出一种GPS/GLONASS一体化定位方案,通过优化求解PZ—90坐标与WGS—84坐标转换关系,探讨利用伪距法确定转换参数,以快速求解整周模糊度为突破,研究一体化定位模型;并对系统进行了总体设计;实验表明GPS/GLONASS一体化定位灵敏稳定、安全高效,在定位中将有广泛应用前景。According to the problems of unitary locating of two location systems （GPS or GLONASS） ： Position data is not accurate; reliability is not well; be liable to environment, and so on, however, in aspect of reliability, precision and efficiency, integrated of GPS/ GLONASS positing has improved evidently. Therefore, the paper puts forward a kind of integrated position scheme of GPS/GLONASS. After optimizing conversion relation of PZ-90 coordinate and WGS-84 coordinate, it discusses calculate conversion parameters by pseudo-range. By taking quickly calculating integer ambiguity as breakthrough, it studies the model of integrated locating; as gone on, the system is overall designed. Expcriment shows that the integrated position of GPS/GLONASS is sensitive and steady, credible and efficient, has extensively application prospect in position.
