摘　　要：给出北斗卫星导航系统(BDS)、GPS、GLONASS三系统间时空统一的转换模型和转换参数,提出GNSS多模融合导航定位时空统一转换方法,并基于Visual C++平台编写多模融合定位程序,用实测BDS/GPS/GLONASS数据进行定位解算,实验验证了时空统一转换方法的正确性;得出多模融合定位精度高,可靠性好的结论。Time system and coordinate system are the reference datum for navigation and positioning, any form of navigation and positioning are carried out within a certain amount of time and coordinate frame. This paper de tailed study spatio tempora unification among Beidou Satellite Navigation System （BDS）, GPS and GLONASS, in troduces the time frame and coordinate frame of the three navigation systems. Gives spatio tempora unification con version model and parameters. On the basis of the theory, puts forward the spatio tempora unification method in practical application of multimode navigation and positioning. Based on the Visual C platform write multimode combinations positioning program, calculate and analyze BDS/GPS/GLONASS three system receiver data, experi mental results show that, multimode fusion positioning have better accuracy and reliability. Verify the correctness and feasibility of spatio tempora unification transformation thought and method in practical application.
