摘　　要：随着靶场试验多星测量系统接收机的使用,针对GPS、北斗单一定位系统定位精度不高、定位可靠性不强、可见星不够的问题,文中充分利用北斗和GPS原始测量信息,在对各系统的测量数据进行时空对准提出了一种基于加权几何精度因子选星的双系统融合解算模型,给出了目标位置和速度解算方法。仿真实验证明,该方法科学合理,其研究结果对北斗系统的精度验证和多星测量系统接收机在靶场的应用具有参考意义。Along with the use of multi - constellation receiver, based on the low positioning precision, low positioning reliability and less visible satellites respectively of single BD or single GPS system, the method of positioning calcmlation and velocity solution on two systems was studied in this paper, which is based on selecting satellites of weight GDOP. Two coordinate systems and time systems were uniformed before calcmlation. The simulation results indicate this method is correct and reasonable, the result has reference value on precision of BD system and its application of multi-constellation receiver for range test.
